Summary: | The invention provides a control device, capable of performing sine wave driving through less calculated amount. A control device that is a control device for a three-phase brushless motor includes: an externally applied voltage acquisition unit that acquires externally applied voltage applied to the three-phase brushless motor; a rotation speed calculation unit that calculates rotation speed of the three-phase brushless motor; a storage unit that stores a voltage advance angle map in which the externally applied voltage and the rotation speed and a voltage advance angle are associated with each other under a condition that a magnetic flux component Id of the magnetic flux component and a torque component of phase current is constant; and a voltage advance angle calculation unit that calculates the voltage advance angle based on the externally applied voltage acquired by the externally applied voltage acquisition unit, the rotation speed calculated by the rotation speed calculation unit, and the voltage advan |
