The AC Induction Engine (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and industrial applications. Induction Ac Induction Motora china devices are by significantly the biggest group of all industrial electrical machines, converting around 70-80% of all electrical energy into mechanical type. 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 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 does not have any moving contacts, which eliminates sparking
