This research investigates how the design variables of ball bearing change the bearing stiffness and the natural frequencies of a HDD spindle system in elevated temperature. It shows that large contact angle reduces the variation of the bearing stiffness and the natural frequencies in elevated temperature. It also proposes a robust design of the spindle motor, in which the wave spring maintains the constant preload even in elevated temperature. The theoretical investigation shows that the reduction of natural frequencies due to temperature rise is almost negligible in the proposed HDD spindle system.
