摘要： The invention relates to a magnetic rotary position sensor that detects the absolute position of a rotation angle as an electric output in a non-contact state with magneto-electric transducers for converting a magnetic flux variation into a voltage. The magnetic rotary position sensor of the invention includes a cylindrical yoke, semi-cylindrical first and second magnets, and magneto-electric transducers. Here, the first and second magnets are disposed on the inside of the yoke to face to each other, and are magnetized in a manner that the N-pole and S-pole face to each other. The magneto-electric transducers are placed in the magnetic field generated by the first and second magnets, rotate against the first and second magnets, and are disposed at a position to detect the magnetic field in the tangential direction of a circle in which the center of the circle coincides with the center of the yoke and the radius of the circle is equal to or larger than half the outline width of the magneto-electric transducers.

摘要： The magnetic pole position detector for an electric motor comprises a detection rotor, a detection stator, and magnetic flux concentration tips and magneto electro transducers. The detection rotor is fixed to an axis of rotation of the motor and comprised of disc-like rotors having first toothlike protrusions and a permanent magnet. The disc-like rotors are assembled so as to make the first toothlike protrusions coincide in the axial direction and the permanent magnet is fixed between the disc-like rotors. The detection stator is comprised of stator cores comprised of an annular yoke and stator teeth formed at regular intervals on the former. Second toothlike protrusions are formed on the inner end of the stator teeth. The stator cores are assembled with a gap in the axial direction so as to make respective second toothlike protrusions coincide in the axial direction. The magnetic flux concentration tips and the magneto electro transducers are placed in the gaps in the axial direction. The detection rotor and the detection stator are assembled with a gap in the radial direction. The magnetic pole position is obtained by detecting the magnetic flux flowing through the stator teeth that varies in accordance the rotation of the detection rotor.
