Motor drive control device, motor unit, and motor drive control method

A motor drive control method, comprising:

• a first step of calculating an operation amount of a motor such that the motor rotates at a target rotation speed;
• a second step of setting an advance angle value such that the advance angle value increases as a rotation speed of the motor increases;
• and
• a third step of generating a drive control signal for controlling driving of the motor according to the operation amount, and outputting the drive control signal at a timing determined based on the advance angle value and a rotational position of a rotor of the motor,
• wherein the second step includes
• a fourth step of setting a reference value each corresponding to the rotation speed as the advance angle value, and
• a fifth step of setting a value corrected to be greater than the reference value set in the fourth step as the advance angle value when a degree of increase in the rotation speed satisfies a predetermined condition.
