AC Motor Working Principle

The basic working principle of an AC Motor mainly depends on magnetism. The basic AC Motor includes a wire coil & two permanent magnets nearby a shaft. Once an alternating current is supplied to the wire coil, then it turns into an electromagnet that produces a magnetic field. This motor includes two essential parts like stator and rotor. This stator includes a wire loop, a solid metal axle, freely moving metal parts that conduct electricity, a coil, a squirrel cage, etc.

 

In the stator of an AC motor, we can transmit the power toward the external coils to make up the stationary part like the stator. The coils of wire can be activated in pairs, in series to generate a magnetic field that turns approximately the exterior of the ac motor.

 

The rotor is balanced within the magnetic field which is changing constantly because of the rotation thus, based on the electromagnetism law; the magnetic field can generate an electric current within the rotor.

 

If the conductor used in this is a wire or a ring, then current supplies in a loop around it, or if the conductor is a solid metal piece simply, then eddy current will flow around it. The current induced can generate its magnetic field & based on another electromagnetism law, the rotary magnetic field will rotate also. Once the magnets interact, then the coil of wires & shaft will start to turn the motor.
