摘要： Magnetic members are arranged along a straight line and can be placed face-to-face with spin-valve magnetoresistive elements. The magnetic pole faces of the magnetic members which can be face-to-face with the spin-valve magnetoresistive elements have different magnetic polarities from the magnetic pole faces of neighboring magnetic members. The magnetic members are arranged at a uniform pitch. Each magnetic member is spaced from neighboring magnetic members. X/P is from 40% to 60%, where X is length of each magnetic member along an arrangement direction of the magnetic members, and P is pitch of the magnetic members along the arrangement direction.

摘要： A magnetostrictive torque sensor comprises a rotary shaft rotating around its center axis and having a magnetostrictive characteristic and a cylindrical ferrite magnetic core disposed at a predetermined distance from the outer periphery of the rotary shaft and coaxially with the rotary shaft and having on its inner peripheral surface a coil serving to detect the strain of the rotary shaft and having an insulating cover. The cylindrical ferrite magnetic core has a pair of opposed coil-forming inner peripheral surfaces defined by dividing the inner peripheral surface into two parts along a plane including the center axis. The coil has, on the respective opposed paired inner peripheral surfaces, a first coil including a going-current coil and a returning-current coil disposed in the same position at an angle of +45° to the center axis, adapted to flow a going current and a returning current in the same direction, and connected in series and a second coil including a going-current coil and a returning-current coil disposed in the same position at an angle of −45° to the center axis, crossing the first coil at right angles, adapted to flow a going current and a returning current in the same direction, and connected in series.

摘要： A magnetostriction-type torque sensor has a rotating shaft having magnetostrictive properties and first and second coils which each constitute three or more closed loops. For each coil, the closed loop is disposed in a concentric relationship (a concentric circle located on a plane perpendicular to the rotating shaft) with the rotating shaft. Further, the direction of magnetostrictive properties of the rotating shaft detected by the first coil is made different from the direction of magnetostrictive properties of the rotating shaft detected by the second coil.
