Abstract
An under-the-hub spin motor for a disk drive includes a stabilizer for supporting the outer diameter of the stator to stiffen the base of the spin motor. Stiffening the base in the region surrounding the shaft of the motor increases the resonant frequency of the spin motor, increasing the tolerance of the spin motor to applied vibrations. The stabilizer may be a ring formed integrally with the base plate of the disk drive or the mounting flange of the motor.
