摘要： PROBLEM TO BE SOLVED: To provide a rotation angle detecting device which determines any abnormality in a computed rotation angle with simple configuration. SOLUTION: This rotation angle detecting device 1 is provided with: a signal output device 13; and a rotation angle operational equipment 14. The signal output device 13 outputs two sine wave signals different in phase by 90 degrees each other depending on rotation of a rotary shaft 10. The rotation angle operational equipment 14 computes the rotation angle from these two sine wave signals. There is a correspondence relation between the two sine wave signals and the rotation angle, and therefore, the rotation angle is determined to be normal or not by previously-setting this relationship as an expected value to compare those two sine wave signals and the rotation angle with this expected value. Thus the rotation angle is computed, while detecting any abnormality in the computed rotation angle is detected in a simple configuration. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a torque sensor that reduces output variation to be generated due to a magnetic flux that directly reaches from a multipolar magnet to a magnetic sensing part when the multipolar magnet and a yoke are integrally rotated.SOLUTION: A torque sensor 103 including a multipolar magnet 14 is formed by mounting two magnetic sensors 41, 42 adjacent to each other in a circumferential direction, on a magnetism collecting part 52 of a pair of magnetism collecting ring 502 that collects magnetic fluxes from the yokes 31, 32. The magnetic sensors 41,42 are arranged so that the magnetic sensing parts 410, 420 are symmetric with respect to an axial center surface V that passes through a central position in a thickness direction of the magnetic sensors 41, 42, in an axial direction of a torsion bar 13. When the multipolar magnet 14 and the yokes 31, 32 are integrally rotated, output variations of the magnetic sensors are increased/decreased in the same direction with respect to the rotation angle. An ECU 91 calculates an output of the magnetic sensor 41 and an output of the magnetic sensor 42, to cancel the output variation.

摘要： PROBLEM TO BE SOLVED: To detect a rotating state of a direct-current motor with a brush with high accuracy independently of a rotational speed while controlling a torque fluctuation without providing a sensor of an encoder or the like. SOLUTION: A power supply unit 5 applies an alternating-current voltage superposed upon a direct-current voltage to a motor 2. A current including an alternating-current component flows when the motor 2 rotates. In the motor 2, a first phase coil L1 among phase coils L1, L2 and L3 for 3 phases is connected in parallel to a capacitor C1, impedance of a motor circuit between each of brushes 16 and 17 changes by the capacitor C1 according to rotation of the motor 2, and the change appears as an amplitude change of the alternating-current component of a motor current. A signal processor 22 extracts the alternating-current component from the motor current detected by a current detector 21, and generates a rotation pulse corresponding to the amplitude change. A rotation angle detector 7 detects a rotation angle of the motor 2 based on the rotation pulse. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a rotation angle detector that is less likely to be affected by external magnetic field, and that is capable of increasing the magnetic field density, imparted from a magnet to the first and second magnetic sensors.
SOLUTION: The first and second magnetic sensors 3, 4 are arranged along an axial direction of the magnet 2, and the magnet 2 is magnetically attracted axially to direct a magnetic force line along the axial direction, and generates a sine curve magnetic field, in response to a rotation angle of the magnet 2, with respect to the first and second magnetic sensors 3, 4. The underface of the magnet 2 is covered with a yoke 5, comprising a disk made of a magnetic substance. Since the yoke 5 effects the magnetic shielding function on the underface of the magnet 2, the external magnetic field will not reach the first and second magnetic sensors 3, 4, even if the external magnetic field is supplied from the underface of the magnet 2. A magnetic efficiency is enhanced in the underface side of the magnet 2 by the yoke 5, the magnetic density imparted from the magnet 2 to the first and second magnetic sensors 3, 4 is also enhanced as a result thereof, angle detection errors are thereby restrained to be small, and robustness is thereby enhanced also.

摘要： PROBLEM TO BE SOLVED: To provide a rotation angle detector capable of preventing a rotation detection error from being generated, even if relative positional shifts are generated between a magnet and the first and second magnetic sensors.
SOLUTION: The two disk-shaped magnets 2, having the same direction of magnetic flux and the same performance, are fixed onto a shaft 1 made of a magnetic substance with a prescribed space. A closed magnetic field with magnetic flux lines aligned radially is formed, in a space in a z-axis direction central part of the two magnets 2 and in the center of an outer circumferential end of the shaft 1 and an outer circumferential end in the magnets 2. The first and second magnetic sensors 3, 4 are arranged in the space formed with the closed magnetic field. The first and second magnetic sensors 3, 4 are arranged in the vicinity of a circumference of the one magnet 2 in conventional rotation angle detectors, the rotation detection errors thereby become large, because of the positional shift between the first and second magnetic sensors 3, 4; but the rotation detection errors are prevented from being generated in the constitution of the present invention, since changes in the directions of the magnetic flux lines imparted to the first and second magnetic sensors 3, 4 are restrained, even if the attachment positions for the first and second magnetic sensors 3, 4 are slightly shifted.
