Background

An electric Motor (Motor) is a device that converts electrical energy into mechanical energy. The electromagnetic power generator utilizes an electrified coil (namely a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form magnetoelectric power rotating torque. The motors are divided into direct current motors and alternating current motors according to different power supplies, most of the motors in the power system are alternating current motors, and can be synchronous motors or asynchronous motors (the rotating speed of a stator magnetic field of the motor is different from the rotating speed of a rotor to keep synchronous speed). The motor mainly comprises a stator and a rotor, and the direction of the forced movement of the electrified conducting wire in a magnetic field is related to the current direction and the direction of a magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field exerts force on current to rotate the motor.

An Engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including, for example, internal combustion engines (reciprocating piston engines), external combustion engines (stirling engines, steam engines, etc.), jet engines, electric motors, etc. Such as internal combustion engines, typically convert chemical energy into mechanical energy. The engine is suitable for a power generation device, and can also refer to the whole machine (such as a gasoline engine and an aircraft engine) comprising the power device.
