Tips: Brushed hub motor vs. Brushless hub motor
The energization principles of brushed hub motors and brushless hub motors are different, and their internal structure is also different. For the hub motor, the output mode of the motor torque (whether it is decelerated by a gear reduction mechanism) is different, and its mechanical structure is also different.
- The internal mechanical structure of a common high-speed brush motor. This kind of in wheel motor consists of a built-in high-speed brushed motor core, reduction gear set, overrunning clutch, hub end cover and other components. High-speed brushed and gear hub motors are internal rotor motors.
- The internal mechanical structure of a common low-speed brush motor. This type of hub motor is composed of carbon brushes, phase converters, motor rotors, motor stators, motor shafts, motor end covers, bearings and other components. Low-speed brushless gearless hub motors are external rotor motors.
- The internal mechanical structure of common high-speed brushless motors. This kind of in wheel motor consists of a built-in high-speed brushless motor core, planetary friction roller, overload clutch, output flange, end cover, hub shell and other components. High-speed brushless gear hub motors are internal rotor motors.
- The internal mechanical structure of common low-speed brushless motors. This kind of hub motor is composed of motor rotor, motor stator, motor shaft, motor end cover, bearing and other components. Low-speed brushless gear hub motors are external rotor motors.
