Abstract
A driver supplies driving power to a motor including an extractor that extracts a part of externally supplied power and a supply unit that supplies the power extracted by the extractor to an external device. The driver includes an output unit that outputs, to the motor, driving power for the motor on which first power to be supplied to the external device is superimposed. The output unit adjusts the first power to be superimposed by controlling a d-axis current value in a driving current for the motor. This structure allows stable power supply to the external device associated with the motor.
Claims11
A driver for supplying driving power to a motor including an extractor to extract a part of externally supplied power and a supply unit to supply the power extracted by the extractor to an external device, the driver comprising:
- an output unit configured to output, to the motor, driving power for the motor on which first power to be supplied to the external device is superimposed,
- wherein the output unit adjusts the first power to be superimposed by controlling a d-axis current value in a driving current for the motor.
