Abstract
An electric power steering apparatus includes a motor condition detector for detecting a stationary, i.e., zero-rotating-speed condition of an electric motor, and a motor resistance calculating section for, when the motor is at the zero rotating speed, executing a division of a voltage supplied to the motor and a current flowing through the motor to thereby calculate a winding resistance value of the motor. Thus, the apparatus can determine an actual winding resistance value of the motor at the zero rotating speed.
