The AC Induction Motor (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and Ac Induction Motora china industrial applications. Induction machines are by significantly 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 ideal for high-speed applications. With appropriate 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 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
