    Abstract: The present invention relates to a method of manufacturing a sensor rotor with a minimum waste of material. The sensor rotor is manufactured by forming a plurality of ring pieces having outer and inner edges that are identical in curvature to each other, arranging the ring pieces in the shape of a ring, magnetizing the ring pieces to create opposite magnetic poles alternately in the circumferential direction of the ring pieces to form a magnetized ring, and fixing the magnetized ring to the inside of a press-in ring. Since the outer edge of each ring piece substantially coincides with the inner edge of the adjacent ring piece, it is possible to eliminate the waste of material between the adjacent ring pieces.

    Abstract: An angular displacement sensor for limited angle applications (e.g., for sensing automotive throttle positions) comprising first (14) and second (16) relatively rotatable components arranged to confront each other axially. The first component (14) provides a plurality of poles (14A, B, C) which are angularly disposed about the rotation axis and extend towards the second component. These poles (14A, B, C) have axes which extend in the same direction as the rotation axis. Some poles have windings (14A, B), while others (14B) provide flux return paths. The second component comprises an inductance affecting component (16) which overlies only some of the wound poles at any given time, the relative rotation varying the poles which are overlaid. The sensor includes an output unit (17) for providing output signal data related to the inductances of the excitation poles and thus related to the rotary configuration of the components.

    Abstract: The variable-reluctance servocontrolled linear motor comprises an electromagnet formed by a shell and by a winding around a displacement path, a magnetic portion mobile in the direction of displacement, guided mechanically so as to have a single degree of freedom with respect to the shell, under the effect of the force exerted by the electromagnet. A detector circuit is formed by an inductive or capacitive measurement sensor for the instantaneous value of the air gap and delivers a signal sd representative of the displacement of the mobile magnetic portion. A subtracter circuit receives a displacement control signal e and the signal sd representative of the displacement in order to deliver a displacement error signal .epsilon. for the mobile magnetic portion. A current amplifier circuit receives the error signal .epsilon. and delivers a supply current to the winding. A restoring element for the mobile magnetic portion exerts on the latter a restoring force opposed to the force exerted by the electromagnet. The restoring element can be mechanical or constituted by a counter-electromagnet.

    Abstract: A rotation angle sensor has a cylindrical rotating member attached to a cam shaft of an internal combustion engine for rotation therewith, and a pickup. The rotating member has a portion formed on its inner peripheral surface for detection of a crank angle. The pickup has a column-shaped support portion and is attached coaxially with the rotating member with the support portion rotatably inserted into a hole which is formed in a casing of the internal combustion engine. A detecting portion provided at a distal end of the support portion is positioned inside the rotating member to detect a position of the crank angle detection portion during rotation of the rotating member and output a signal. The pickup further has an arc-shaped elongate hole which is formed to extend about a central axis of the support portion, so that the pickup is fixed to the casing of the internal combustion engine with a bolt inserted through the elongate hole. The pickup, by loosening the bolt, is easily turned to change its angular position with respect to the rotating member. Thus, ignition timing of the internal combustion engine, which is controlled based on the signal from the rotation angle sensor, can be easily adjusted and the structure for the adjustment is simple and inexpensive.
