Abstract
To provide a motor control circuit that variably controls the speed of a motor, in which an appropriate advance angle value corresponding to the speed of the motor that is set can be automatically set. The motor control circuit according to the present invention includes an advance angle setting means that adds a reference advance angle value to an advance angle correction value obtained by multiplying a proportional coefficient by a correction amount and outputs an advance angle setting signal, and an advance angle setting correction means that uses a ratio of a correction reference period relative to a period of a reference signal input from the outside as a correction amount and corrects the reference advance angle value by an advance angle correction value obtained by multiplying the correction amount by a predetermined proportional coefficient of the advance angle setting means.
