[0002] The electric power steering system is a mechatronic product, consisting of a steering column, a torque sensor, a servo motor and a control module. The system starts working after the vehicle is started. When the vehicle speed is lower than a certain speed, these signals are sent to the control module. The control module sends control instructions to the servo motor based on the steering wheel torque, rotation direction, vehicle speed and other data, so that the servo motor outputs torque of corresponding size and direction to generate auxiliary force. When the vehicle is not turning, the electronic control unit does not send torque signals to the servo motor, and the servo motor current tends to zero. The servo motor housing, as a protective component for the installation of the servo motor, provides important safety guarantees for the operation of the motor body.
