Abstract
An electric power steering apparatus includes an rotating AC machine which generates an auxiliary torque for assisting a steering torque of a steering system; and a controller which performs control so that the allowed electric current amplitude of the rotating AC machine becomes large if a rotational speed of the rotating AC machine is increased. Accordingly, it is possible to release or lessen the limit on the number of repetitions or continuous time of the 'stationary steering' or the 'end contact'.
