Advantages and classification of motors

The hub motor is built into the hub and directly drives the wheels. Its biggest feature is the integration of power and transmission devices into the wheel hub, greatly simplifying the mechanical part of the electric bicycle, making it more beautiful, lightweight, and efficient. In the early days, due to limitations in precision and materials, friction often occurred due to insufficient precision, resulting in noise and wear issues. With the continuous development of industrial technology, the production of motors has become very sophisticated, overcoming various early problems.

There are two types of hub motors: gear hub motors and gearless hub motors.

The advantage of a gear hub motor (commonly known as a high-speed motor) is the internal design of a clutch device, which makes the resistance of the vehicle sliding or manually stepping on the pedal when the electric vehicle is turned off or the battery is dead more than that of a gearless hub motor under the same conditions. Low resistance. Therefore, it is widely used by electric vehicle manufacturers.

The internal structure of gearless hub motors (commonly known as low-speed motors) is relatively traditional. There are no duplicate planetary reduction gears. It adopts a direct drive type, relying directly on electromagnetic conversion to generate mechanical energy to drive electric vehicles. The disadvantage is that without a clutch device, it is necessary to overcome electromagnetic resistance when riding without power. Generally speaking, the cost of a gearless motor is lower than that of a geared motor.
