Power Steering Assist Motor
The Power Steering Assist Motor is a part of your car's electric power steering system. This system uses an electric motor instead of a hydraulic pump. The assist motor is controlled by the ECU which determines the assistive torque to be exerted on the wheels. The motor is connected to the steering column or gear.
When the steering wheel turns, it turns the input shaft which, in turn, twists the torsion bar. The torque sensor senses the torque on the torsion bar. The ECU uses the data from the torque sensor to determine the speed of the assist motor. The assist motor turns a worm gear to transmit the motion to the steering column. This steering system is more efficient than the hydraulic steering as the assist motor does not derive any power directly from the engine.
If your assist motor is defective, it will cause your power steering to fail. If you find that the steering is rougher than usual, it is likely that the power steering assist motor is at fault. You should replace the motor at the earliest to prevent your steering system from sustaining further damage.
