Ac Induction Motor

The AC Ac Induction Motora china Induction Motor (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and industrial applications. Induction machines are by significantly the largest group of all commercial electrical machines, converting approximately 70-80% of all electrical energy into mechanical form. The employ a robust rotor construction, which makes them suitable for high-speed applications. With appropriate design, they have good overloading and field weakening features.

The ACIM is comprised of a straightforward cage-like rotor and a stator containing three windings

The changing field produced by the AC line current in the stator induces a current in the rotor which interacts with the field and causes the rotor to rotate

The rotor does not have any moving contacts, which eliminates sparking
