An under-the-hub spin motor (7) for a disk drive includes a stabilizer (60) for supporting the outer diameter of the stator (16) to stiffen the base of the spin motor (7). Stiffening the base in the region surrounding the shaft (12) of the motor (7) increases the resonant frequency of the spin motor (7), increasing the tolerance of the spin motor to applied vibrations. The stabilizer (60) may be a ring formed integrally with the base plate (10) of the disk drive or the mounting flange (10) of the motor. |
