Abstract
Methods and systems for demagnetizing a rotor. The method includes, in one example, adjusting a position of magnetic poles mounted on a frame in a demagnetization system in relation to a first electric machine rotor, and decreasing the magnetization of the first electric machine rotor via operation of the demagnetization system to generate an electromagnetic field.
