The AC Induction Engine (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and industrial applications. Induction machines are by much the Ac Induction Motora china largest group of all industrial electrical machines, converting around 70-80% of all electricity into mechanical form. The employ a robust rotor construction, making them ideal 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 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
