Abstract
Disclosed is a system and method for mounting disk drive motors. The motor spindle and the drive shaft are rotatably supported by the disk drive chassis. The drive shaft of the motor extends through the printed circuit board of the disk drive and into a central aperture in the motor stator. Between the motor stator and the printed circuit board is a stator-spacer which positions and aligns the stator. The stator is mechanically mounted and electronically connected to the printed circuit board by means of stator retaining pins. The rotor bell of the motor is coaxially mounted to the drive shaft and inductively disposed about the stator.
