This motor control device comprises: a PWM demodulation processing unit for demodulating a PWM command signal (Si) into a speed command value (Vr); a rotation control unit for generating a motor driving value (Dd) according to the speed command value (Vr); an energization driving unit for generating driving voltages (Uo, Vo, Wo) for driving coils according to the driving value (Dd) so that currents flow through the coils; a rotational speed calculation unit for generating a speed detection value (Vd) as a notification signal to be notified outside; and a PWM modulation processing unit for generating a PWM notification signal (Fp) that is pulse-width-modulated by the speed detection value (Vd). The PWM modulation processing unit generates and sends out the PWM notification signal (Fp) synchronized with the PWM command signal (Si). |
