Abstract
A motor control apparatus includes a detection unit configured to detect an actual rotation position of a motor, a control unit configured to provide position feedback control on the motor so that the detected actual rotation position sequentially approaches a plurality of target rotation positions, and a processing unit configured to perform, before the position feedback control starts, processing to make an initial position deviation fall within a predetermined range, the initial position deviation being a difference between the actual rotation position and a first target rotation position of the plurality of target rotation positions.
