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

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

The changing field made 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 doesn’t have any moving contacts, which eliminates sparking
