Ac Induction Motor

The AC Ac Induction Motora china 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 much the largest group of all industrial electrical machines, converting around 70-80% of all electrical energy into mechanical form. The have a very robust rotor construction, making them suitable for high-speed applications. With proper design, they have good overloading and field weakening characteristics.

The ACIM is made up of a simple 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
