摘要:
A hard disk drive with a spindle motor that rotates a disk. When the disk drive is exposed to low temperatures a current can be provided to the spindle motor to heat the motor. For example, a DC current can be provided to the spindle motor. The current flowing through the spindle motor coil generates heat. The current can be provided for a predetermined time interval to sufficiently heat the spindle motor so that the fluid bearings of the motor can operate. The current is terminated and then an AC current is provided to the spindle motor to cause motor rotation.
