The motor control apparatus includes a power supply function of supplying electric power from a power supply to a motor, a rotational position detecting function of performing detection of a rotational position of a rotor of the motor for respective phases of the motor, and outputting first rotational position data indicative of result of the detection, a control function of controlling a power supply operation of the power supply function in accordance with the first rotational position data, and an induced voltage detecting function of performing detection of induced voltages of the respective phases of the motor. The control function controls the power supply operation of the power supply function in accordance with result of the detection performed by the induced voltage detecting function when the first rotational position data are abnormal.
