The rotor has a 3phase winding, with the three terminals connected to separate slip rings, which are normally connected to a liquid rheostat or resistor bank. The rheostat is used for starting, and can be disconnected once the motor is up to speed. By changing rotor resistance with the rheostat, the motor speed can be changed.
