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

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
