PROBLEM TO BE SOLVED: To provide a motor control circuit excellent in advance-angle control.SOLUTION: A motor control circuit 100 compares a target frequency inputted to a first signal input terminal 152 of an FLL circuit 150 with a feedback frequency of an FG signal inputted to a second signal input terminal 154 of the FLL circuit 150, and controls a drive-waveform generating circuit 160 and an advance-angle control circuit 170 on the basis of the frequency difference. The drive-waveform generating circuit 160 includes a sinusoidal-signal generating circuit 164, and a sinusoidal signal generated by the sinusoidal-signal generating circuit 164 is phase-controlled by a digital signal outputted from the advance-angle control circuit 170. |
