摘要： A magnetic disc drive motor comprises a hub for carrying magnetic discs on its outer periphery, a drive magnet rigidly fitted to the inner periphery of the hub, a stator core having a coil wound around it and juxtaposed with the drive magnet and a motor frame having a substantially cylindrical holder for rigidly holding the stator core, wherein the space between the stator core and the motor frame is filled with a resin material. A compact and simply configured magnetic disc drive motor can thus be realized, which is capable of rotating magnetic discs in a very stabilized manner.

摘要： A motor control circuit provides reduced stopping time. The circuit utilizes n rotational signals whose relative phase differences are proportional to the rotational speed of the motor. Inverted logic signals are formed of these n signals. Circuitry for discriminating the direction of the motor and for determining from the n signals n-1 and/or n inverted signals, the initial change of any of the signals following a reversal of the motor. Upon determining the initial change, a signal is supplied to the motor drive circuit to cause the motor to de-energized. A specific circuit for holding the motor in a stopped condition is disclosed.
