The rotor winding is not wound by insulated wires, but by aluminum or copper strips welded or cast by short-circuit rings, and the three-phase asynchronous motor is called a squirrel cage motor. Squirrel cage motor is one of the three-phase asynchronous motors, and three-phase asynchronous motors are divided into squirrel cage motors and winding motors.
Small three-phase squirrel cage asynchronous motors have the advantages of small size, light weight, and good quality, so they are widely used in agricultural production and township enterprises.
