Abstract
Methods and systems for controlling an electric motor are provided. The electric motor includes at least one winding. A winding current flowing through the at least one winding is monitored. The winding current has an oscillating component and an offset component. The offset component of the winding current is isolated from the oscillating component of the winding current. The electric motor is controlled based on the offset component of the winding current.
