The difference between the tooth and the toothless in the electric bicycle hub motor
Dec 01, 2018

Electric bicycle hub motor, as its name implies, integrates the motor motor into the inside of the flower drum. After the power is turned on, the motor converts the electric energy into mechanical energy, which drives the wheel to rotate, thus driving the vehicle forward. It is widely used by electric vehicles with its mature design and low price. .

There are two types of electric bicycle hub motors, namely a gear hub motor and a gearless hub motor. Geared hub motors were limited in accuracy and material in the early stages, and frictional forces were generated due to insufficient precision, causing problems such as noise and wear. With the development of industrial technology, most of the gear hub motors are now produced very well, so you don't have to worry about this.

Moreover, when the electric vehicle is turned off or the battery is de-energized, the clutch device designed inside the single-wheel hub motor of the electric tooth assists the resistance of the vehicle to slide or the human pedaling to be smaller than that of the non-gear hub motor under the same condition. Therefore, it is widely used by electric vehicle manufacturers.

The internal structure of the gearless electric assist single wheel hub motor is relatively traditional. There is no replica planetary reduction gear, which directly relies on electromagnetic conversion to generate mechanical energy to drive the electric vehicle. Therefore, it is necessary to overcome the electromagnetic resistance when the power is off, but also because of this, the hub motor of this structure can convert kinetic energy into electrical energy and store it in the battery when going downhill.
