Abstract

An motor hub design is disclosed that will be used spindle motor in HDD. If a spindle motor cylindrical hub contacts with a disk inner surface, after thermal stress cycles, disk shift might occur due to the thermal expansion mismatch. To avoid this, to have circumferential air gap between a spindle motor cylindrical hub and a disk inner surface
