The AC Induction Motor (ACIM), sometimes called a squirrel cage motor, is one of the most Ac Induction Motora china popular motors used in consumer and industrial applications. Induction machines are by significantly the biggest group of all industrial electrical machines, converting around 70-80% of all electricity into mechanical form. The employ a robust rotor construction, making them suitable for high-speed applications. With correct design, they have good overloading and field weakening features.
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
