The E-bike crank motor kit is an integral part of the electric assist bicycle. The main function is to convert electrical energy into mechanical energy. It uses a coiled coil, that is, a stator winding to generate a rotating magnetic field and acts on the rotor squirrel-cage closed aluminum. The frame forms a magnetoelectric rotational torque.
The E-bike crank motor kit is divided into a DC motor and an AC motor according to the use of the power source. Most of the motors in the power system are AC motors, which may be synchronous motors or asynchronous motors. Regardless of the type of motor, it consists of a stator and a rotor. The direction in which the energized conductor is forced to move in the magnetic field is related to the direction of the current and the direction of the magnetic induction line.
The working principle of the electric assist bicycle crank motor kit is that the magnetic field acts on the current to force the motor to rotate. It is therefore also a rotary electric machine that converts electrical energy into mechanical energy. It mainly consists of an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, it has a current passing through the armature squirrel cage aluminum frame and is rotated by the action of the magnetic field.
