The AC Induction Motor (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and commercial applications. Induction devices are by significantly the biggest group of all industrial electrical machines, converting around 70-80% of all electricity into mechanical form. The have a very 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 simple 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 Ac Induction Motora china causes the rotor to rotate
The rotor doesn’t have any moving contacts, which eliminates sparking
