摘要： A scooter motor includes a stator unit, a rotor unit and a brake unit. The stator unit is fixedly mounted on the fixed shaft of the motor, and the rotor unit is rotatably mounted on the fixed shaft. The brake unit includes a friction plate component and an electromagnetic clutch component. The electromagnetic clutch component is configured to drive the friction plate component to press to brake. According to the embodiment of the present invention, the scooter motor drives the rotor unit to rotate by the cooperation between the stator unit and the rotor unit to drive the scooter, additionally, the stator unit controls the rotation of the rotor unit by using the friction plate component and the electromagnetic clutch component to realize the braking of the scooter.
