  • Disk storage drive
    Patent number: 4599664
    Abstract: A motor for direct or coaxial drive of a disc storage, mounted in a center hole formed in a storage disc includes a rotor and a stator which form together with an air gap separating the rotor from the stator a magnetic circuit. The stator has a single-phase winding. The motor produces an auxiliary reluctance moment complementing the electromagnetic torque produced by the winding and being offset in time relative to the electromagnetic torque. Due to the positioning of the motor within the center hole of the disc a very compact construction is obtained.
    Type: Grant
