The AC Induction Motor (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and commercial applications. Induction machines are by significantly the biggest group of all commercial electrical machines, converting approximately 70-80% of all electrical energy into mechanical type. The have a very robust rotor construction, making them ideal for high-speed applications. With proper 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 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 Ac Induction Motora china sparking
