Motor driving control device and motor driving control method

Abstract

There is provided a motor driving control device and a motor driving control method capable of quickly activating a motor. The motor driving control device comprises a motor driving unit, a control circuit unit and a position detector. The motor driving unit selectively energizes coils Lu, Lv, Lw of a plurality of phases of the motor. The control circuit unit outputs a driving control signal C1 to the motor driving unit to switch, in a predetermined order, an energization phase of the coils Lu, Lv, Lw of the plurality of phases to be energized by the motor driving unit. The position detector outputs a position signal corresponding to a position of a rotor of the motor. The control circuit unit adjusts the energization phase based on the position signal when the motor is activated, thereby matching variation timing of a phase of the position signal and the energization phase with each other, and outputs the driving control signal C1 according to a period of the position signal after the activation of the motor.
