Spindle motor with soundproofing
The Journal of the Acoustical Society of America, 1998A spindle motor comprises a soundproof wall formed on a stator outside a peripheral surface of a rotor. Noise generated inside the motor during the operation is cut off by the wall to be reduced remarkably. Since the soundproof wall has no influence on the volume of the motor, a slim-type motor can be realized.
