摘要： A rotation angle sensing device for detecting a relative rotation angle between a rotor and a stator includes main magnets, fixed in the rotor, and hole ICs, fixed in the stator. The hole ICs detect magnetic flux of the main magnets , and the relative rotation angle therebetween is detected. A supportive magnet is disposed between the hole ICs so as to offset the magnetic flux of the main magnets. Accordingly, a rotation angle in which the magnetic flux density detected in the hole ICs becomes 0 [mT] can be changed by the supportive magnet. Therefore, a 0° position of the rotation angle can be set to the rotation angle in which the magnetic flux density is detected as 0 [mT], and moreover the detectable range of the rotation angle can be enlarged to be more than 90°.

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： Non-contact type Hall ICs detecting an rotation angle of a throttle valve, a stator core strengthening a magnetic field around the Hall ICs, a lead frame connecting the Hall ICs to an outside ECU are integrated in a sensor cover by resin molding. Thus, the Hall ICs, the stator core, and the lead frame are accurately positioned in the sensor cover. As a result, the Hall ICs are accurately positioned with respect to a permanent magnet disposed in a shaft side of the throttle valve, thereby improving an accuracy of detecting the rotation angle of the throttle valve.

摘要： A stator core has a detecting portion located on a center of a gap penetrating the stator core in a diametric direction and a Hall IC arranged in the detecting portion. Large gap portions each having a distance G3 wider than a distance G2 of the detecting portion are formed on both sides of the detecting portion. Therefore, a magnetic flux passing through the stator core is concentrated into the detecting portion, and the magnetic flux density passing through the Hall IC is increased. As a result, an output of the Hall IC is increased. The large gap portion is formed to narrower a distance G4 on an outer side of the stator core, and the distance G4 is wider than an air gap G1 between the permanent magnet and the stator core.

摘要： A compact and high-accuracy angular position measuring device is provided which has magnets installed in a rotor core and a magnetic sensor installed in a stator core. The magnetic sensor produces an output indicative of an angular position of the rotor core as a function of a change in density of magnetic flux produced by the magnets. The magnets are so arranged in the rotor core that the same poles are opposed magnetically to produce a repellent force in magnetic fields of the magnets, thereby causing the magnetic flux to go to the magnetic sensor through the rotor core. This eliminates the need for an air gap between the stator core and the poles of the magnets which is formed in a conventional device, thus allowing the device to be reduced in size and an error in output of the device to be decreased.
