  • Disk drive motor
    Patent number: 5124604
    Abstract: An axial gap motor for use in a disk drive includes a rotatable magnet rotor and fixed first and second windings closely spaced from the rotor. The rotor and windings are disposed coaxially about a rotatable spindle to which the rotor is mounted. Current supplied to one winding actuates the rotor to rotate in a run mode. Current supplied to the other winding positions the rotor for maximum torque for starting the motor, and enables the sensing of the speed of the rotating rotor.
