The AC Induction Electric motor (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and industrial applications. Induction machines are by much the biggest group of all commercial electrical machines, converting around 70-80% of all electrical energy into mechanical type. The employ a robust rotor construction, making them ideal for high-speed applications. With Ac Induction Motora china appropriate design, they have great overloading and field weakening characteristics.
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 does not have any moving contacts, which eliminates sparking
