Electric bicycle hub motor mechanical structures:

Brush motor and brushless motor have different energization principles, and their internal structures are not the same. For the electric bicycle hub motor, the motor torque output (whether through the reduction gear body) is not the same, then they will have different mechanical structures.

1, Common high-speed brush motor internal mechanical structure. This wheel hub motor from the built-in high-speed brush motors heart, reduction gears, clutch, wheel cover and other components. Brush with high-speed hub gear motor is within the rotor.

2, common low-speed brush motor internal mechanical structure. This wheel motor from the carbon brushes, commutator, rotor, stator, motor shaft, motor end caps, bearings and other components. Brush speed gearless hub motor is external rotor motor.

3, common high-speed brushless motor of the internal mechanical structure. This wheel motor from the built-in high-speed brushless motors heart, planetary roller friction, overload clutch, output flanges, end caps, wheel housings and other components. High-speed brushless geared hub motor is within the rotor.

4, common low-speed brushless motor of the internal mechanical structure. This wheel motor from the rotor, stator, motor shaft, motor end caps, bearings and other components. Low-speed brushless gearless hub motor is external rotor motor.
