  • Speed sensitive field ground detection mode for a generator field winding
    Patent number: 6798210
    Abstract: A method for locating a speed sensitive ground condition in a field winding of an electromagnetic synchronous machine having a rotor and an excitation circuit, the method including: sensing a magnetic flux generated by the field winding, while accelerating the rotor and activating the excitation circuit; detecting a cyclical aberration in the magnetic flux occurring during revolution of the rotor, and determining a position in the field winding corresponding to the cyclical aberration and identifying that position as a location of the speed sensitive ground condition.
    Type: Grant
