Description:

An AC motor is a device that converts electrical energy from alternating current into mechanical energy. The AC motor is mainly composed of an electromagnet winding or distributed stator winding to generate a magnetic field and a rotating armature or rotor. The electric motor is made by using the phenomenon that the energized coil rotates under the force of a magnetic field. AC motors are classified into synchronous AC motors and induction motors.
The stator winding of a three-phase AC motor is basically three coils separated by 120 degrees from each other for triangle or star connection. When three-phase current is applied, a magnetic field is generated in each coil, and these three magnetic fields are combined to obtain a rotating magnetic field.
