Tips: Brushless motor application in electric system bicycle

Electric bicycles are generally welcomed by consumers because they are light, fast and adapt to the modern demand for environmental protection, efficiency and safety. As a kind of green transportation, electric bicycle requires high efficiency and adaptability of motor. Motor is the key of electric bicycle technology, and the progress of motor technology is closely related to the development of power electronics technology. In the case of limited energy, the efficiency of the motor directly affects the main whole vehicle index of the electric bicycle, its volume, weight and appearance also directly affect the shape of the whole electric bicycle, while the reliability of the motor also directly affects whether the electric bicycle can be accepted by the majority of consumers.

In the application of electric bicycle, if the service life of brush motor is 80,000 km, then the service life of brushless DC motor is more than 200,000 km. Compared with brush motors, the controller of brushless motors is relatively complex, and the control part adds electronic commutation, which makes the reliability and economy of the controller greatly improved. Brushless DC motors are widely used in electric bicycles because of their advantages such as no brushes and mechanical commutator, no reduction device and low noise.
