The motor control apparatus controlling rotation of a brushless motor includes a controller to control an angular velocity of the motor, and a load torque calculator to calculate a load torque at which the motor drives a driven member, by using a detection signal output from a rotation detector to output the detection signal in response to the rotation of the motor. When the motor drives the driven member toward a target stop position, the controller calculates a deceleration rotation amount, which is a remaining rotation amount of the motor at start of deceleration of the motor from its drive state that is one of an acceleration state and a constant velocity state, and controls the angular velocity of the motor on a basis of the deceleration rotation amount. The controller calculates the deceleration rotation amount by using the load torque calculated in the drive state. |
