Original Abstract Submitted

a motor control apparatus includes a current supply unit and a control unit. the current supply unit supplies a coil current to a plurality of coils of a motor by controlling a voltage applied to the plurality of coils based on a target value of an excitation current and a target value of a torque current. the control unit sets the target value of the excitation current to a first target value in a first period within a period in which a rotation speed of the motor is controlled to be a target speed, and sets the target value of the excitation current to a second target value larger than the first target value in a second period different from the first period.
