A motor control apparatus that controls rotation of a rotor of an electric motor powered from an electric power source includes a learning portion that executes an initial drive learning process, and a controller that executes a normal drive operation to sequentially change an exciting phase of the electric motor based on a count value of a counter which is corrected by a correcting portion such that the rotor is rotated to a target position after an initial drive operation is finished. The learning portion re-executes the initial drive learning process after a predetermined condition is satisfied, when the initial drive learning process is failed.
