Abstract
An electric power steering system according to the present invention comprises: a sensor module including a steering torque sensor and a control circuit housed therein; and a motor module including an electric motor and a motor driving circuit housed therein. The sensor module and the motor module are physically separately mounted in the electric power steering system. Since the sensor module and the motor module are physically separated, these modules can separately be produced, and the steering torque sensor and the electric motor can independently be adjusted.
