摘要： An improved rotation angle detecting device that detects a rotation angle of a first member relative to a second member is proposed. The rotation angle detecting device includes a magnet unit fixed to the first member and a pair of magnetic sensors fixed to the second member to provide output signals whose phase is different from each other at 90 degrees in angle. The magnet unit includes a pair of disk plates that has the same magnetic poles at the same circumferential positions and is disposed at a prescribed axial distance and a shaft that is made of magnetic material to support the disk plates at the center thereof. The magnetic unit provides a uniform magnetic field in a space around the shaft between the pair of disk plates, and a pair of magnetic sensors is disposed in the space.

摘要： A rotation angle detecting device that detects a rotation angle of a rotating object includes a permanent magnet that generates magnetic fields in response to rotation of the rotating object, a magnetic sensor, a first yoke and a second yoke. The magnetic sensor includes a pair of close integrated magnetic sensing elements, such as hall elements, disposed at a position around the permanent magnet so that one of the sensing elements senses magnetic field at a phase different from the other. The first yoke and the second yoke forms two magnetic paths crossing each other at the magnetic sensor.

摘要： External magnetic members are provided outside the outer periphery of a rotor. When the rotor is positioned around its turning angle of 70 degrees, part of the magnetic fluxes generated by magnets pass through the external magnetic members. This makes it possible to reduce the magnetic fluxes passing through Hall ICs around the turning angle of 70 degrees, thereby linearizing the change characteristic of the magnetic flux density. Thus, it is possible to generally linearize the change characteristic of the density of the magnetic fluxes through the Hall ICs 7, with the detectable angle range kept wide.

摘要： An electromechanical conversion device includes an electromechanical conversion unit and a cable, which has a signal wire and a ground wire for grounding the electromechanical conversion unit. The electromechanical conversion unit performs a conversion between a relative movement with respect to a magnetic field generation unit and electrical signals, based on a magnetic field generated by the magnetic field generation unit. The signal wire is connected with the electromechanical conversion unit to transfer the electrical signals, and has a first branch portion and a second branch portion which extend substantially parallel to the ground wire and are respectively arranged at two opposite sides of the ground wire. A distance between the first branch portion and the ground wire is substantially equal to that between the second branch portion and the ground wire.
