Current sensing in a disk-drive spindle motor |
摘要 |
One embodiment of the invention includes a disk-drive spindle motor power regulator system. The system includes a switching system comprising at least one power transistor for each of a plurality of phases of a disk-drive spindle motor. The system also includes a switching controller configured to generate a plurality of switching signals configured to control the at least one power transistor for each of the plurality of phases of the disk-drive spindle motor. The system further includes a current monitor configured to measure a magnitude of an individual phase current through at least one of the plurality of phases of the disk-drive spindle motor. |
