Abstract

PURPOSE:To conduct transfer between one-two phase excitation and two phase excitation easily without stopping a motor by excellently taking timing at the time of the changeover of one-two phase excitation and two phase excitation. CONSTITUTION:A timing generating circuit 1 generates timing signals displaying timing when the phase of a motor is changed over and the timing of transfer between one-two phase excitation and two phase excitation. A motor control circuit 2 controlling the phase of the motor, a motor drive circuit 3 and the motor 4 are driven by the timing signals. The timing signal is outputted at the time of the changeover of phase is a changeover to one-two phase excitation from two phase excitation in the timing. The timing signal is not outputted until one phase excitation reaches two phase excitation even when a changeover signal is outputted on one phase excitation in a changeover to two phase excitation from one-two phase excitation.
