    摘要: A magnetic shield made of magnetic material in the shape of a thin cylinder is externally fitted and fixed on a cylindrical mold member holding magnetic flux collecting rings so that it has extended sections with appropriate length on both sides in the axial direction, and therefore magnetic noise from outside in the radial direction is shielded directly by the outer surface of the magnetic shield, magnetic noise from both sides in the axial direction is shielded by concentrating the magnetic noise on the end faces of the magnetic shield, and the influence on the magnetic flux collecting rings held in the mold member is eliminated.

    摘要: A torque detecting apparatus having a permanent magnet fixed to an input shaft, magnetic yokes fixed to an output shaft coaxially connected to the input shaft via a torsion bar and disposed within a magnetic field of the permanent magnet to form a magnetic circuit, and a Hall IC for detecting a magnetic flux induced by the magnetic yokes. The permanent magnet is of a truncated conical shape, and the bevel circumference surface thereof is magnetized by magnetic poles alternately in a reverse polarities along circumference direction, so as to oppose the magnetic yokes. A torque applied to the input shaft or the output shaft can be detected through detection by the Hall IC of the magnetic flux generated between the magnetic yokes. The configuration allows reducing the length in an axial direction of the input shaft.

    摘要: An electric power steering system of a vehicle has a plurality of Hall ICs for sensing torque applied to a steering wheel, and an electric motor for power-assisting the steering wheel. A supply voltage for the Hall ICs is varied temporarily to check the electric output signals of the Hall ICs. A non-failing device of the plurality of Hall ICs, which generates the electric output signal varying in response to the variation of the supply voltage, is selected. The electric motor is controlled based on only the electric output signal of the non-failing device.
