AC induction motors are the most common electric motors in the world. These simple, reliable and economical motors are found in refrigerators, washing machines and furnaces, as well as conveyors, pumps, winders, wind tunnels and other industrial equipment.
What is the difference between AC motor and induction motor?
Difference between Three Phase Induction Motor and Synchronous Motor. … The stator winding of Induction Motor is energized from an AC source. Synchronous Motor always runs at synchronous speed, and the speed of the motor is independent of load, but an induction motor always runs less than the synchronous speed.
How does a 3 phase AC induction motor work?
How it works. To actually achieve torque at the motor shaft, a current is applied across the stator. This creates a rotating magnetic field which in turn induces a current in the rotor. Because of this induced current, the rotor also creates a magnetic field and starts to follow the stator due to magnetic attraction.
What is the principle of an induction motor?
The motor which works on the principle of electromagnetic induction is known as the induction motor. The electromagnetic induction is the phenomenon in which the electromotive force induces across the electrical conductor when it is placed in a rotating magnetic field.
