Ac Induction Motor

The AC Induction Motor (ACIM), sometimes called a squirrel cage motor, is one of the most popular motors used in consumer and industrial applications. Induction devices are by much the biggest group of all commercial electrical machines, converting around 70-80% of all electricity into mechanical form. The have a very robust rotor Ac Induction Motora china construction, making them ideal for high-speed applications. With correct design, they have good 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 produced 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
