Ac Induction Motor

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

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 does not have any moving contacts, which eliminates sparking
