摘要： An improved motor apparatus includes five motor coils which are connected with a stator and are sequentially energizeable to cause a rotor to nutate and rotate relative to the stator. Control circuitry includes an upper transistor and a lower transistor which are connected with opposite ends of a motor coil. The upper transistor is rendered nonconducting and current is conducted from one end of the motor coil through the lower transistor back to the motor coil to maintain the motor coil energized. A holding circuit is effective to energize one of the coils to maintain gear teeth on the stator and rotor in meshing engagement to hold the rotor against movement to relative to the stator. Annular rim surface areas on the stator and rotor are maintained in abutting engagement during nutation and rotation of the rotor relative to the stator and during holding of the rotor stationary with the gear teeth in meshing engagement. Upon de-energization of all of the motor coils, a biasing spring is effective to rotate the rotor relative to the stator to move the rotor back toward an initial position relative to the stator.
