Baichen's Analysis of Electric Wheelchair Motor Technology: The Scientific Choice Between Brushed and Brushless Motors

Precise Matching of Performance Characteristics and Usage Scenarios

In the core power system of electric wheelchairs, the debate over the technical routes of brushed and brushless motors has always been a focus of industry attention. These two distinct power solutions offer diverse choices for users with different needs.

Technical Principles: A Collision of Traditional Classics and Modern Innovation

Brushed motors utilize the classic principle of electromagnetic induction, achieving current commutation through the physical contact between carbon brushes and the commutator. This century-old proven technology is simple and reliable, delivering peak torque instantly upon startup. Real-world testing data shows that brushed motors deliver approximately 15% higher torque during startup than brushless motors of the same power, making them superior when starting on inclines.

Brushless motors represent the latest advancements in electronic technology, achieving precise current commutation through an electronic controller. The elimination of physical contact points eliminates mechanical wear, increasing energy conversion efficiency to over 85%.

Performance Analysis: Advantages and Disadvantages in Different Scenarios

In terms of range, brushless motors demonstrate a clear advantage. Thanks to higher energy conversion efficiency, brushless motor systems can offer up to 20% more range than brushed motors with the same battery capacity. This difference is significant for users who need to travel long distances.

Regarding maintenance, brushed motors require carbon brush replacement every 2000-3000 hours of use, and the dust generated by brush wear needs regular cleaning. Brushless motors, with no easily damaged parts, only require regular cleaning, significantly reducing maintenance frequency and costs.

Noise control is also a crucial factor. The mechanical commutation of brushed motors produces continuous friction noise, typically around 55 decibels. The electronic commutation of brushless motors is virtually silent, with operating noise levels below 40 decibels, making them particularly suitable for quiet environments such as libraries and hospitals.

convenient maintenance networks.

High-end individual users tend to prefer brushless motors. Although the initial investment is higher, the low maintenance costs and superior quiet operation over the long term offer significant value for users who value quality of life. Consumers in Europe and North America particularly appreciate this long-term value proposition.

Users in special environments need to consider specific factors. Users in hilly areas may value the high torque characteristics of brushed motors; while in scenarios requiring long-term continuous use, the stability and low heat generation of brushless motors are more advantageous.

Purchase Recommendations: Make an informed decision based on comprehensive considerations

For elderly users, it is recommended to prioritize models with easy-to-operate brushed motors. Their gentle acceleration characteristics and mature maintenance system are more suitable for elderly users with lower technical literacy. Choosing a model with a soft-start function can further enhance safety.

Active young and middle-aged users are more suited to brushless motor products. The longer driving range and precise speed control can meet their diverse travel needs. Models with multi-speed adjustment are recommended to adapt to different usage scenarios.

Institutional purchasers need to make choices based on usage intensity. For locations with low usage frequency, brushed motors can be chosen to control costs; while hospitals or rental service providers with high usage intensity should invest in brushless motors to reduce long-term operation and maintenance costs.
