WebAugust 20, 2007 What Causes Inductive Imbalance in Wound Rotor Motors? Although shorted turns in the stator windings can be a source of a high imbalance, inductive imbalance seen on the stator windings of a wound rotor motor can often be the result of a fault in the rotor field or resistor bank. WebThis will adversely affect the Standard Test results, possibly creating higher than normal resistive and inductive imbalances. Wound Rotor Electric Motor Testing Wound rotor motors have a three-phase winding wound on the rotor which is connected to three phases of start-up resistors in order to provide current and speed control on start-up.
