Abstract
A magnetic torquer sensor for a steering system includes a magnetic unit, a magnetism-collecting unit, and a magnetic sensing element. The magnetic unit has a magnet ring. The magnetism-collecting unit has an inner magnetism-collecting ring and an outer magnetism-collecting ring. The inner magnetism-collecting ring has inner magnetism-collecting portions. The outer magnetism-collecting ring has outer magnetism-collecting portions. The outer magnetism-collecting portions and the inner magnetism-collecting portions are arranged alternately. The inner magnetism-collecting portions have their inner surfaces spaced from the magnet ring by a predetermined interval and level with inner surfaces of the outer magnetism-collecting portions. The magnetic sensing element is arranged at outer surfaces of the inner and outer magnetism-collecting rings for sensing magnetic-field variation between the inner and outer magnetism-collecting rings when they rotate with respect to the magnet ring. Thereby, the steering system provides good linearity.
