Proximity switches and circumferentially movable stator windings allow a motor-generator to simultaneously sense and switch from a synchronous motor position to a synchronous generator position. This mechanism replaces the conventional separate sensing and switching of motor-generator functions. Automatic rotational repositioning of the stator maintains constant voltage and prevents the generation of transient voltages or harmonics. The stator flux leads the rotor magnetic flux slightly in an import power or motor position, creating a torque on the rotor and a counter torque on the stator reacted by the fixed casing of the apparatus. As the stator field weakens due to a failure of the normal power supply, the counter torque also weakens and the stator windings are biased to begin to turn with the rotor until the rotor and stator fields are in step, i.e., when virtually no current is generated or consumed or until a full export power or generator position is reached. The dynamic stator may also be used in electric motors or generators to filter or cushion variations in the power supply or in the load.
