  • Alternating current motor with directional rotation reliability
    Patent number: 4728832
    Abstract: A bi-directional alternating current permanent magnet motor is disclosed that is operated with a rotational restraint that insures proper directional rotation of a load. The motor output shaft is loosly coupled to a pinion gear. In the event that the motor is unable to start in the correct direction, and inadvertently reverses itself, it is immediately unloaded. This unloading causes the motor to stop and start again in the correct direction with a momentum that typically is sufficient to run the motor and its gear train in the correct direction.
