The AC Induction Engine (ACIM), sometimes called a squirrel cage motor, is one of the most Ac Induction Motora china popular motors used in consumer and commercial applications. Induction devices are by far the largest group of all industrial electrical machines, converting around 70-80% of all electricity into mechanical type. The employ a robust rotor construction, making them suitable for high-speed applications. With appropriate 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 doesn’t have any moving contacts, which eliminates sparking
