Given that brushed DC motors are being gradually replaced by brushless motors, why do brushed DC motors still maintain a market presence?

Who Is Still Using Brushed DC Motors These Days?

Brushed DC motors in small appliances

Despite the growing adoption of brushless motor technology, small appliances remain a major consumer of brushed DC motors. Devices such as handheld fans, electric shavers, hair dryers, and kitchen gadgets continue to rely on brushed motors due to their simplicity, low cost, and compact design. Brushed motors provide adequate torque and speed for these applications without requiring complex electronic controls or additional driver circuitry.

Manufacturers in this sector prioritize cost-effectiveness and ease of assembly. The simplicity of a brushed motor allows production lines to operate efficiently and with minimal specialized training. Additionally, the small size and low power requirements of many appliances make the efficiency gains of brushless motors less impactful, reducing the incentive to switch.

Automotive accessories and peripheral devices

The automotive sector continues to use brushed DC motors extensively in 2025, particularly for accessories and peripheral systems. Examples include power seat adjustments, window regulators, ventilation fans, and small pumps. In these applications, reliability, predictable torque characteristics, and the availability of standardized parts outweigh the benefits of higher efficiency or longer lifespan offered by brushless alternatives.

Brushed motors also integrate well with existing vehicle electrical systems. Automotive manufacturers and suppliers often rely on proven motor designs to meet strict regulatory and durability requirements. Switching to brushless solutions may introduce additional development complexity, cost, or compatibility concerns, making brushed motors the practical choice for many accessory functions.

Medical consumable and low-power devices

Medical consumable equipment, such as small pumps, portable diagnostic devices, and sample handling tools, still makes frequent use of brushed DC motors. These motors are compact, easy to control, and readily available from established suppliers. The moderate performance requirements of disposable or semi-disposable medical devices reduce the need for brushless alternatives.

In addition, regulatory approval processes for medical devices can be lengthy and costly. Using a familiar brushed motor allows manufacturers to leverage existing designs and documentation, avoiding delays in product certification. Reliability, safety, and predictable maintenance schedules often outweigh incremental efficiency gains in these contexts.

Low-end automation and consumer electronics

Low-end automation systems, such as entry-level conveyors, vending machines, small robotic kits, and motorized toys, remain reliant on brushed DC motors. The primary reasons are cost constraints, simplicity, and the maturity of the supply chain. Brushed motors can be sourced inexpensively, assembled with minimal electronic support, and replaced easily when needed.

Consumer electronics, including portable devices, battery-operated toys, and audio/video peripherals, continue to use brushed motors where noise, weight, and compactness requirements are moderate. Brushless motors could improve efficiency and reduce wear, but the added electronics and driver costs often exceed the budget allocated for mass-market consumer products.

Reasons for maintaining brushed motor designs

Several factors explain why these sectors continue to rely on brushed DC motors even when brushless alternatives exist. First, the initial cost of brushless motors and their controllers is higher, which can significantly affect high-volume, low-margin products. Second, brushed motors are simple to implement, requiring minimal electronic control and allowing straightforward assembly and replacement. Third, the performance of brushed motors is sufficient for the specific torque, speed, and duty cycle requirements of many applications. Finally, maintenance and repair in existing supply chains are easier because the components are widely understood and supported.

The role of mature supply chains

Mature supply chains play a central role in the continued use of brushed motors. Many manufacturers have established sourcing, logistics, and assembly processes built around standard brushed motor models. Suppliers offer consistent quality, predictable delivery times, and extensive technical support, which reduces risk for production planners.

Switching to brushless solutions would often require requalification of suppliers, redesign of motor mounts, adjustments to electronic drivers, and staff retraining.

In 2025, sectors ranging from small appliances to automotive accessories, medical consumables, low-end automation, and consumer electronics demonstrate that brushed motors remain relevant where proven performance, availability, and predictable production processes outweigh the incremental benefits of brushless alternatives.

Are Brushed DC Motors Being Used in Applications Where They Shouldn't Be?

Instances of outdated or inappropriate motor selection

In some industries, brushed DC motors are still used in applications where performance expectations have evolved beyond their capabilities. Common examples include high-speed machinery, precision automation systems, and noise-sensitive environments. In these cases, the continued reliance on brushed motors often stems from legacy designs, cost considerations, or lack of awareness about alternative solutions. As technology advances, maintaining older motor choices without reevaluation can create limitations in efficiency, reliability, and long-term maintainability.

In particular, industries that prioritize high throughput or continuous operation, such as conveyor systems, automated inspection equipment, or laboratory instrumentation, sometimes continue using brushed motors out of habit. These applications benefit more from brushless motors that offer lower wear, longer life, and consistent performance under demanding conditions.

Performance boundaries in high-speed and long-lifetime scenarios

Brushed DC motors have inherent mechanical limitations due to their commutator and brush system. At high speeds, friction, arcing, and brush wear increase significantly, which can lead to premature failure, heat buildup, and inconsistent performance. Similarly, in applications requiring extended continuous operation, brushes and commutators degrade over time, limiting motor lifespan and increasing maintenance needs.

Applications such as high-speed pumps, industrial mixers, robotic actuators, or medical devices that operate continuously or require precise control often exceed the optimal operational envelope of brushed motors. In these contexts, brushless motors provide higher efficiency, lower thermal stress, quieter operation, and extended service life. Continuing to use brushed motors in such applications can introduce hidden costs related to maintenance, downtime, and eventual equipment replacement.

Noise-sensitive and precision applications

Another area where brushed motors face limitations is in noise-sensitive or precision-driven environments. The mechanical contact of brushes produces audible noise and electrical ripple, which can be problematic in laboratory instruments, medical diagnostic equipment, or compact consumer electronics requiring quiet operation. Additionally, variations in brush wear or contact can introduce speed fluctuations that compromise accuracy in positioning, timing, or assembly operations.

For applications where low vibration, minimal acoustic output, and precise control are critical, brushed motors may not be suitable. Despite this, legacy designs and conservative procurement practices sometimes result in their continued deployment, leading to performance compromises that could have been avoided with brushless alternatives.

Technical debt from continued use of old designs

Procurement decisions that default to established brushed motor solutions contribute to what can be described as technical debt. Companies may opt for familiar motors to minimize short-term costs or avoid redesign efforts, but this strategy accumulates hidden costs over time. These costs manifest in more frequent maintenance, higher energy consumption, performance variability, and eventual redesign needs.

Technical debt is particularly evident in automated manufacturing or service operations where high reliability, repeatability, and low downtime are required. While brushed motors might function adequately initially, over time the limitations in lifespan, thermal tolerance, and noise control create pressure to upgrade. This delayed transition often ends up costing more than selecting the appropriate motor technology from the outset.

Application Type	Brushed Motor Limitation	Impact	Alternative Recommendation
High-speed pumps	Brush wear at high RPM	Reduced life, overheating	Brushless DC motor with electronic control
Continuous conveyor systems	Limited duty cycle	Frequent maintenance, downtime	Brushless motor or AC servo
Medical diagnostic devices	Electrical noise, vibration	Interference with measurement, patient discomfort	Brushless motor or stepper motor
Laboratory automation	Torque fluctuation under load	Reduced precision, calibration issues	Brushless or precision servo motor
Noise-sensitive consumer electronics	Audible brush noise	User dissatisfaction, perceived low quality	Brushless motor

Legacy designs driving persistent use

One reason brushed motors continue to appear in borderline applications is the persistence of legacy designs. Product families developed years ago relied on brushed technology for simplicity and cost reasons. Updating the design to brushless technology may require changes in electronics, mechanical interfaces, or thermal management, which some organizations defer to reduce short-term expenses.

While this approach mitigates immediate risk and capital outlay, it locks the product into older performance characteristics. As regulatory standards, user expectations, and competitive offerings evolve, the consequences of sticking with outdated motor technology become more pronounced, potentially affecting product competitiveness and lifecycle costs.

Cost versus long-term performance considerations

Cost remains a central factor in motor selection. Brushed motors are cheaper upfront, easy to source, and well-understood by assembly and maintenance teams. This financial advantage explains why some organizations continue to specify them even when higher efficiency, lower noise, or longer lifetime would be more beneficial in the long term.

However, the total cost of ownership, including maintenance, downtime, energy consumption, and eventual replacement, often favors a brushless solution. Decision-makers who focus only on immediate procurement costs may underestimate the cumulative impact of choosing brushed motors in marginally suitable applications.

Guidelines for avoiding inappropriate use

To prevent misapplication, organizations should define performance envelopes for brushed motors, including maximum speed, duty cycle, torque consistency, noise thresholds, and operational lifespan. Any application exceeding these parameters should prompt evaluation of brushless alternatives or other motor types. Procurement teams should also periodically review legacy designs to identify opportunities for modernization, reducing accumulated technical debt and improving product reliability.

Awareness of limitations and proactive motor evaluation

Brushed DC motors continue to serve industries effectively in applications where simplicity, cost, and supply chain maturity are paramount. However, they are sometimes deployed in scenarios where high speed, long life, low noise, or precise control are critical. In these cases, continued use reflects a combination of legacy design inertia, short-term cost focus, and technical debt. Understanding these limitations and periodically evaluating alternative motor technologies helps align performance, efficiency, and long-term operational goals, reducing risks associated with outdated choices.

How Does It Work? — What Technical Details Are the Industry Focusing On?

Brushes, commutators, and the real service life

Brushed DC motors operate on the principle of electrical current passing through stationary brushes to a rotating commutator, which energizes the rotor windings. The physical contact between the brushes and the commutator enables torque generation but also introduces wear. Over time, brush degradation and commutator surface erosion reduce performance and can lead to failure. Manufacturers and users are increasingly attentive to the expected service life under realistic operating conditions, considering factors such as duty cycle, load, speed, and ambient environment. Service life is often shorter than theoretical ratings due to these cumulative mechanical effects.

Understanding wear patterns is critical for applications requiring high reliability. Factors such as brush hardness, spring tension, commutator finish, and operating temperature all influence the rate of wear. Continuous monitoring or preventive maintenance can extend operational lifespan, but these approaches increase complexity and operational overhead. Industry discussions focus on quantifying realistic life cycles rather than relying solely on nominal specifications.

The influence of materials, coatings, and structural design

Material selection and structural design have a significant effect on brushed motor performance. Copper, graphite, or composite brushes each offer different trade-offs in conductivity, friction, and wear resistance. Commutators may feature coatings such as silver or tin to improve electrical contact and reduce arcing. Similarly, rotor windings, laminations, and insulation materials impact efficiency, heat dissipation, and torque characteristics.

Manufacturers experiment with structural refinements, such as optimized brush angles, commutator segmentation, and improved ventilation, to enhance operational stability. Even minor changes in component geometry can affect torque ripple, vibration, and thermal behavior. In addition, housing and bearing selection influence durability and noise levels. These factors are essential in industrial, consumer, and medical devices where predictable performance over time is critical.

Common industry "upgrade strategies"

To extend the relevance of brushed motors, manufacturers adopt several technical strategies aimed at improving efficiency, reducing sparking, and minimizing noise. Reducing friction at the brush-commutator interface is a primary approach, often achieved through optimized brush material, shape, and spring pressure. Arcing is mitigated by adjusting commutator segment design or applying surface coatings that improve conductivity.

Noise reduction is another focus. Vibrations caused by torque ripple, brush chatter, or mechanical resonance can be addressed through precision assembly, rotor balancing, or structural damping. In some cases, electronic circuits are added to limit peak currents or smooth voltage supply, which indirectly reduces acoustic and electrical noise.

Efficiency improvements are also pursued by reducing internal losses, optimizing winding resistance, and improving magnetic flux density. These changes help maintain torque output while reducing energy consumption and heat buildup, especially important for battery-powered devices where efficiency directly affects runtime and thermal performance.

Technical Focus	Implementation	Performance Impact
Brush material and shape	Graphite, copper-graphite, composite	Wear rate, friction, torque stability
Commutator coatings	Silver, tin, surface polishing	Reduced arcing, improved efficiency
Rotor and lamination design	Optimized winding patterns, laminated cores	Reduced eddy current loss, lower vibration
Spring tension and brush angle	Adjustable or optimized per design	Consistent contact, lower noise, reduced wear
Ventilation and housing	Open frames, fan integration, bearing placement	Improved thermal management, quieter operation

Comparison with brushless DC motor control systems

One of the key contrasts between brushed and brushless DC motors lies in control system complexity. Brushed motors operate with simple voltage input, relying on mechanical commutation to generate motion. Brushless motors, by contrast, require electronic controllers, sensors, or sensorless algorithms to manage rotor position, commutation timing, and speed. This adds cost, design complexity, and software considerations, but it enables higher efficiency, precise torque control, and longer service life.

For industries evaluating motor choice, this distinction affects both performance expectations and total system design. Brushed motors excel in simplicity, predictable behavior without external controllers, and lower upfront cost. Brushless alternatives allow more sophisticated performance but require additional components and integration effort. Decisions often weigh immediate cost, required operational parameters, and maintenance considerations against these trade-offs.

Industry focus on maintenance and reliability metrics

Technical discussions increasingly emphasize measurable reliability indicators such as brush life, commutator wear, noise levels, and torque stability under load. For applications in small appliances, automotive accessories, medical consumable devices, and consumer electronics, these metrics are critical. Standardizing how these characteristics are tested and reported is a growing concern, particularly when comparing brushed and brushless solutions.

Manufacturers often conduct accelerated life testing, thermal cycling, and vibration analysis to evaluate motor endurance. Data from these tests informs design adjustments and helps users anticipate maintenance schedules. Attention to these technical details ensures that brushed motors continue to function effectively where they remain suitable, while also identifying scenarios where alternative motor technologies might be preferable.

Balancing simplicity, cost, and performance

Ultimately, the technical details highlight the balance between simplicity and performance that brushed DC motors offer. Optimizing brush material, commutator design, and rotor structure can deliver adequate performance for many consumer and light industrial applications without requiring complex electronic controllers. At the same time, awareness of limitations such as wear, noise, and efficiency ensures that these motors are deployed appropriately and maintained effectively.

The industry’s ongoing focus on these technical details reflects a pragmatic approach: maintaining the relevance of brushed motors where their characteristics align with application needs while clearly understanding the boundaries where brushless alternatives are more suitable. This balance guides both design evolution and informed procurement decisions.

Pros and Cons – What Can Brushed DC Motors Do, and What Can't They Do?

Advantages of brushed DC motors

Brushed DC motors remain widely used in many industries because of their simplicity, low initial cost, and ease of maintenance. Their mechanical commutation allows operation with minimal electronic control, making them compatible with basic voltage sources and straightforward driver circuits. This makes them suitable for cost-sensitive applications where rapid integration and reliability under moderate conditions are prioritized. Repairs are relatively simple; brushes and commutators are accessible and can be replaced without specialized tools or programming knowledge.

The straightforward design of brushed motors also contributes to predictable behavior. Users can anticipate torque output and performance without complex calibration or software configuration. This reliability is particularly valuable in low-to-medium performance applications such as small home appliances, automotive accessories, consumer electronics, and low-end automation systems. The motors deliver adequate performance while keeping system design and operational overhead minimal.

Another advantage is flexibility in control. Brushed DC motors can operate directly from simple voltage sources or basic PWM controllers, making them compatible with a wide range of existing systems. This reduces design complexity and ensures that legacy products can be maintained or upgraded without extensive redesign. In addition, the mechanical design allows a certain level of overload tolerance, which can be important in applications where occasional torque spikes occur.

Limitations and challenges of brushed DC motors

Despite their advantages, brushed DC motors have inherent limitations. The most significant is the wear of brushes and the commutator, which restricts overall service life and requires periodic maintenance. In high-duty-cycle applications, such as continuous small appliance operation or industrial conveyor systems, this wear becomes a critical factor affecting reliability and operational cost.

High-speed and high-precision applications highlight other limitations. Brushed motors struggle to maintain consistent torque at elevated speeds, and mechanical commutation introduces torque ripple. These characteristics make them less suitable for tasks requiring fine motion control, precise positioning, or rapid dynamic response. Noise, sparking, and electromagnetic interference generated at the brush-commutator interface further limit their use in sensitive or safety-critical environments such as medical devices or laboratory equipment.

Environmental factors also influence performance. Dust, humidity, and contamination can accelerate brush and commutator wear, reducing efficiency and creating maintenance challenges. In applications such as automotive ventilation fans or consumer electronics, these environmental considerations can limit the lifespan and reliability of brushed motors compared to brushless alternatives.

Applications increasingly replaced by brushless alternatives

Trends in the industry indicate that high-performance applications are shifting toward brushless DC motors. High-speed fans, precision medical devices, robotics, and battery-powered tools that demand efficiency, longevity, and low maintenance increasingly favor brushless designs. Brushless motors offer higher energy efficiency, more precise speed and torque control, minimal maintenance, and reduced noise and electromagnetic interference.

The adoption of brushless designs is accelerated by technological advances. Compact controllers, integrated sensors, and more affordable power electronics make it feasible to implement precise closed-loop control even in small motors. This allows brushless designs to outperform brushed motors in applications where continuous operation, consistent torque, or long life is critical. The higher initial cost is offset by reduced lifecycle costs, lower maintenance, and higher reliability.

Examples of applications migrating to brushless technology include high-speed centrifuges in medical equipment, precision cooling fans in electronics, and industrial servo motors for automated assembly lines. In these cases, the combination of efficiency, precise control, and long operational life outweighs the simplicity advantages of brushed motors.

Applications still relying on brushed designs

Despite the shift toward brushless solutions, many applications continue to rely on brushed motors effectively. Small household appliances such as vacuum cleaners, electric toothbrushes, and kitchen gadgets, automotive accessories like window regulators and seat adjusters, consumer electronics, and low-end automation systems often prioritize cost, simplicity, and serviceability. In these applications, the benefits of brushed motors align closely with practical requirements.

The maturity of the supply chain plays a significant role. Brushed motors benefit from established manufacturing processes, widespread component availability, and experienced repair infrastructure. For high-volume, cost-sensitive products, these factors outweigh potential performance gains from switching to brushless designs, particularly when reliability expectations can be satisfied with routine maintenance. Long-standing supplier relationships, bulk procurement of brush materials, and standard commutator sizes reduce risk and cost for manufacturers.

In addition, many industries use tried-and-tested designs that have been validated over years or decades. Consumer electronics and small appliance manufacturers often standardize on a specific motor model for multiple products. Changing to brushless designs would require system redesigns, new controllers, and testing, creating a "technical debt" that slows adoption.

Upgrading strategies within brushed motors

Industries continue to optimize brushed motors through incremental upgrades. Brush material, commutator finish, and rotor structure modifications can improve efficiency, reduce noise, and extend service life. Techniques such as carbon-graphite brushes, multi-segment commutators, and low-resistance windings allow brushed motors to perform closer to lower-end brushless alternatives in targeted applications.

Additional strategies include improving heat dissipation, adding spark suppression components, or fine-tuning gear ratios to reduce load on the brushes. These approaches allow manufacturers to extract more performance from established designs while minimizing redesign costs. In some cases, hybrid approaches are used, combining brushed motors with basic electronic controllers to manage speed, torque, or soft-start functions.

Decision factors for continued use

Choosing between brushed and brushless motors requires balancing cost, performance, maintenance, and system complexity. For cost-sensitive applications, the simplicity and serviceability of brushed motors remain compelling. For high-speed, long-life, or low-noise requirements, brushless motors are increasingly preferred. Procurement decisions consider initial cost, lifecycle maintenance, operational demands, and supply chain reliability to determine the most suitable solution.

Balancing tradition and innovation

The motor industry is characterized by a balance between legacy brushed designs and modern brushless alternatives. Brushless motors dominate high-performance, precision, and long-lifetime domains, while brushed motors maintain relevance in cost-sensitive, high-volume, and well-understood applications. By understanding trade-offs, manufacturers, engineers, and buyers can select motor technologies aligned with application requirements, supply chain capabilities, and product life cycle expectations.

What Should Be Considered During Procurement and Design?

Key performance specifications for brushed DC motors

When selecting brushed DC motors for a particular application, several performance specifications must be carefully evaluated. Rated voltage determines compatibility with the power supply and affects overall motor efficiency. Rated speed is important for applications where rotational velocity must match system requirements. Torque output, both starting and continuous, influences the motor's ability to handle load variations and overcome mechanical resistance. Expected lifetime, often dictated by brush and commutator wear, guides maintenance schedules and replacement intervals. Heat management is another critical factor, as excessive temperature can accelerate brush degradation, affect winding insulation, and reduce overall reliability.

Each of these specifications interacts with the others. For example, increasing torque typically increases current draw, which in turn raises heat generation. Designers must consider these interactions to ensure the motor can sustain expected operating conditions without premature failure. Establishing acceptable margins for voltage, speed, torque, and thermal limits is a key step in matching a motor to an application.

Supply chain considerations

Beyond technical specifications, the supply chain plays a central role in procurement decisions. Brush material selection affects wear rate, conductivity, and spark generation. Common materials include carbon, graphite, or copper-graphite blends, each offering different performance and cost trade-offs. Consistency in brush quality across production batches ensures predictable motor behavior and reduces variation in service life. Manufacturing processes, such as rotor balancing, commutator finishing, and insulation application, also influence performance and reliability. Long-standing supplier relationships can provide access to proven materials and process standards, which can reduce risk during large-scale procurement.

After-sales service availability is another critical consideration. Replacement brushes, commutators, and other service components must be accessible. Technical support from suppliers can aid in troubleshooting, design adjustments, and preventive maintenance recommendations. A robust supply chain ensures that both initial procurement and long-term maintenance requirements are met efficiently.

Industry risks and regulatory factors

Brushed DC motors are not isolated from broader market and regulatory influences. Material cost volatility, particularly for copper and specialized brush materials, can affect procurement budgets and production planning. Shortages in high-quality carbon or copper-graphite brushes may force substitutions, potentially impacting motor performance and lifespan. Regulatory constraints related to environmental standards, such as limits on heavy metals or hazardous substances, also influence material selection and manufacturing processes. Compliance with these regulations may require sourcing from certified suppliers, adopting alternative materials, or redesigning motor components.

Market risks can extend to international trade considerations, logistics delays, or sudden shifts in demand. These factors emphasize the importance of building flexibility into procurement strategies, maintaining multiple supply sources, and monitoring price trends to mitigate cost or delivery disruptions.

Emerging trends and hybrid approaches

Recent trends in brushed motor applications include hybrid solutions that combine traditional brush structures with electronic controls. For instance, adding pulse-width modulation (PWM) speed control or current sensing can reduce brush wear, limit sparking, and improve efficiency without fully converting to brushless designs. These hybrid strategies allow existing supply chains and mechanical designs to remain in place while addressing some performance limitations. Manufacturers can achieve longer service intervals, smoother operation, and improved energy efficiency by integrating simple electronics with established brushed motor systems.

These approaches are particularly useful in cost-sensitive applications where a complete transition to brushless technology would be economically prohibitive. Hybrid solutions may also extend the operational envelope of brushed motors in moderate-speed or moderate-torque applications, delaying the need for redesign while improving overall system reliability.
