  • Patent number: 10944351
    Abstract: A motor drive control device capable of reducing the occurrence of vibration in a simple circuit configuration is provided. The motor drive control device (1) includes a motor drive unit (2) that selectively energizes coils with a plurality of phases (Lu, Lv and Lw) of a motor (20) and a control circuit (4) that outputs a drive control signal (Sd) which is a PWM signal to the motor drive unit (2) and thereby controls driving of the motor (20) while switching energization phases of the coils with the plurality of phases (Lu, Lv and Lw) energized by the motor drive unit (2) in predetermined order. The control circuit (4) executes reduction control to temporarily reduce a duty ratio of the drive control signal (Sd) every time a period of 1/m (m is an integer of 2 or more) of a switching cycle of the energization phases elapses after switching the energization phases.
