Method and apparatus for driving a brushless motor using feedback control |
摘要 |
A brushless dc motor has polyphase stator windings and a rotor. The polyphase stator windings have first ends and second ends. The first ends are connected in common at a common junction. Two of the second ends are sequentially selected and a drive current is supplied between the selected two second ends to rotate the rotor. The rotor has magnetic poles arranged in a predetermined configuration. A voltage at the common junction is measured. A rotation of the rotor is controlled in response to the measured common-junction voltage.
