摘要： In a motor drive apparatus, the brushless motor (11) has a three-phase motor structure, the Hall sensor (12) detects a magnetic flux change signal in an operation of the brushless motor (11), the control unit (13) obtains a rotor rotation number of the brushless motor (11) based on the magnetic flux change signal, calculates a predetermined electric angle even when the rotor rotation number is changed, and causes the gate driver (14) to output a PWM signal by which a power distribution timing to each phase of the brushless motor (11) is switched at the predetermined electric angle, and the inverter (15) sinusoidally changes and supplies a voltage supply to a stator coil of the brushless motor (11) based on the PWM signal.
