Sensorless Position Detection for a Brushless Direct Current Motor During Inverter Standby |
摘要 |
A method of controlling a brushless direct current motor without a position sensor. The motor includes a plurality phase windings adapted to be energized by an active inverter circuit that synchronously applies drive voltages through a plurality of phases to produce drive currents in the phase windings. Back electromotive force voltages are detected when the inverter circuit is inactive for sensorless detection of motor position.
