  • How to choose electric wheelchair between brush motor and brushless motor?
    Apr 03, 2018

    Most of the current electric wheelchairs on the market are DC brushed motor control systems. Compared with DC brushless motor control systems, the disadvantages of DC brushed motor control systems are as follows:

    1, friction, loss

    Some friends often encounter this problem when using a brush motor, that is, after using the motor for a period of time, it is necessary to open the motor to clean the brush of the motor, which is time-consuming and labor-intensive. The maintenance strength is no less than a home cleaning. The

    2. Big heat, short life

    Due to the structure of the brush motor, the contact resistance between the brush and the commutator is large, resulting in a large overall resistance of the motor and easy to generate heat. The permanent magnet is a thermal element. If the temperature is too high, the magnetic steel will demagnetize. The performance of the motor is degraded and the life of the brushed motor is affected.

    3. Low efficiency, low output power

    The above mentioned problems with the heating of the brush motor are largely due to the fact that the current does work on the internal resistance of the motor, so the electrical energy is converted into heat energy to a great extent, so the output power of the brush motor is not large and the efficiency is not high.
