ABSTRACT:
A motor is equipped with a magnetic-flux detector, which detects magnetic fluxes from magnets of the motor. A position signal converter finds a position of the motor using a value detected by magnetic-flux detector. A speed controller throws the motor in sine wave drive using the detected motor position.
