Abstract: An electric power steering system includes a housing, a ball screw, a motor, an angular position sensor and a computing unit. The ball screw includes a nut and a threaded shaft. The motor is disposed in the housing and connected to the nut and includes a bushing and a metal component. The metal component is fixed on the bushing and includes a central portion, a first wing portion and a second wing portion. The first wing portion and the second wing portion are disposed on an outer circumferential surface of the central portion. The angular position sensor is disposed in the housing and fixed relative to the housing. The angular position sensor includes a first sensing unit and a second sensing unit. The computing unit is electrically connected to the first sensing unit and the second sensing unit.
