  • Patent number: 4484114
    Abstract: A self-starting DC motor includes first and second main windings and a rotor. A starting winding is angularly offset from the first and second main windings for aligning the rotor offset from the main windings to start the motor from a noncogged position. A timing device is employed to energize the angularly offset windings when the motor is first turned on. After a time sufficient for the rotor to come to rest in its starting position, the starting winding is deenergized. A position sensing device generates signals indicative of the position of the rotor. A switch is responsive to the position indicating signals and alternately energizes the first and second main windings to operate the motor.
