The AC Induction Electric motor (ACIM), sometimes called a squirrel cage motor, is one of the most popular motors found in consumer and commercial Ac Induction Motora china applications. Induction machines are by significantly the biggest group of all commercial 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 proper design, they have great 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
