The AC Induction Electric motor (ACIM), sometimes called a squirrel cage motor, is among the most popular motors found in consumer and commercial applications. Induction Ac Induction Motora china machines are by significantly the biggest group of all industrial electrical machines, converting approximately 70-80% of all electricity into mechanical form. The have a very robust rotor construction, making them suitable for high-speed applications. With correct design, they have good overloading and field weakening features.
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
