자동차용 비접촉식 조향 토크 센서에 관한 연구

We have studied the automotive non-contacted torque sensor of magnetic shielding type for MDPS or EPS, which includes Hall IC, circular permanent magnets and apparatus of magnetic shield using soft ferromagnetic material. This sensor is mounted to torsion bar connected steering column ? shaft assembly. Some samples were made by the magnetic shield concept design and performance tests were carried out.
