    • [Problem] An object of the present invention is to provide a motor control apparatus that, with a high reliability, protects the motor release-switch comprising the semiconductor switching elements in small size and an electric power steering apparatus provided the same. [Means for solving the problem] An electric power steering apparatus that drive-controls a motor by an inverter, and a motor release-switch is connected between the inverter and the motor, comprising: a control section to detect an assist state on a driving control system and to ON/OFF-switch a control of the inverter based on a detection result; a motor rotational number detecting section to detect a rotational number of the motor; an energy calculating section to calculate an energy of a motor back-EMF and a regenerative current based on the rotational number; and a judging section to compare the energy with an area of safety operation of the motor release-switch and to OFF-switch the d motor release-switch when the energy becomes within the area of safety operation. As occasion demands, the area of safety operation is calculated with the temperature.
