The AC Induction Motor (ACIM), sometimes called a squirrel cage motor, is one of the most popular motors used in consumer and commercial Ac Induction Motora china applications. Induction devices are by far the largest group of all commercial electrical machines, converting approximately 70-80% of all electricity into mechanical form. The have a very robust rotor construction, making them ideal for high-speed applications. With correct design, they have great overloading and field weakening characteristics.
The ACIM is made up 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
