vfd on slip ring "wound rotor" motors - Variable Speed ...

2008-2-7 · Rotor resistors alter the slip of the motor and produce high slip losses. At half speed, the power dissipated in the rotor resistors is equal to the power produced to the load. For normal applications, you can apply a VFDto a slip ring motor by shorting out the rotor (no resistors) and applying the VFD to the stator as per a normal induction motor.
