ABSTRACT:
A first current supplier supplies a first current to a first phase coil of a motor. A second current supplier supplies a second current to a second phase coil of the motor. A current selector selects a value of the first current and a value of the second current, so as to make constant at least one of a magnitude of a synthetic vector obtained by the selected value of the first current and the selected value of the second current at every microstep driving step of the motor, and an angular interval between synthetic vectors corresponding to adjacent microstep driving steps of the motor.
