Motors is a device that converts electrical energy into mechanical energy. The principle ofmotor is to generate the rotating magnetic field by using the electrified coil (that is, the stator winding) and act on the rotor squirrel-cage closed aluminum frame to form the magneto electric rotating torque.
The motor is divided into DC motor and AC motor according to the power supply. Most of the motors in the power system are AC motors. Can be synchronous motor or asynchronous motor (motor stator magnetic speed and rotor rotation speed do not maintain synchronous speed.
The motor is mainly composed of the stator and the rotor. The direction of the force motion of the electric wire in the magnetic field is related to the direction of the current and the direction of the magnetic sense (the direction of the magnetic field). The working principle of the motor is the effect of magnetic field on the current force, which makes the motor rotate.
Electric bikes motor power is different, such as the general assembly of 12AH battery four blocks of motor power is 350 W, this refers to the internal gear of the high speed motor. In the case of a brushless toothless motor, the actual power is 250 W.
