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

The ACIM is comprised of a simple 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 doesn’t have any moving contacts, which eliminates sparking
