Spindle motor magnet diameter increase above head plane |
| 摘要 |
A spindle motor for a disk drive including a hub defining a longitudinal axis having a hub flange defining a mounting surface extending substantially normal to the longitudinal axis, wherein the hub flange of the hub extends longitudinally relative to the mounting surface to define a vertical surface; and a motor base coupled to the hub proximate to the hub flange of the hub, the motor base having a central axis substantially aligned with the longitudinal axis, wherein the motor base extends longitudinally, wherein a radius of the motor base is greater than a radius of the hub flange of the hub. |

1. A spindle motor for a disk drive comprising:
a hub defining a longitudinal axis, said hub comprising:
a hub flange defining a mounting surface extending substantially normal to the longitudinal axis,wherein the hub flange of the hub extends longitudinally relative to the mounting surface to define a vertical surface; and a motor base rotor coupled to the hub proximate to the hub flange of the hub, the motor base rotor having a central axis substantially aligned with the longitudinal axis, wherein the motor base rotor extends longitudinally, and wherein a radius of the motor base rotor is greater than a radius of the hub flange of the hub. |
