摘要： A rotation angle detecting device is rotated by a rotating object via a gear mechanism to detect a rotation angle of the rotating object. The rotation angle detecting device includes a housing, a magnet rotor unit having a permanent magnet and a central hole, a magnetic sensor unit including a pair of magnetic sensor elements each of which detects magnetic flux density of a magnetic field generated by the permanent magnet in a direction different from the other, and a signal processor that calculates a rotation angle of the rotating object from the magnetic flux density. The magnetic rotor unit includes a mechanism for changing the magnetic flux density as the number of turns of the magnet rotor unit changes.

摘要： A rotation angle detecting device includes a columnar permanent magnet that has a generally ring-shaped cross-section and a pair of magnetic poles, a pair of semi-cylindrical yokes disposed in a circumferential direction opposite the permanent magnet, a rotary shaft fixed to the permanent magnet at a shifted rotation axis and a magnetic sensor disposed in one of circumferential gaps between the yokes. The rotation axis and the magnetic poles are arranged so that the magnetic flux density becomes maximum at portions of the yoke less than 90 degrees angled from the circumferential gap in which the magnetic sensor is disposed.

摘要： A rotation angle detecting device includes a signal generator, a magnetic rotor and a rotation angle calculating unit that calculates a rotation angle θ of the rotor based on the output signals of the signal generator. The signal generator includes a magnetic rotor that has a permanent magnet and a shaft connectable with the rotating object and at least three magnetic sensor elements disposed in the magnetic field to generate a plurality of output signals when the rotor rotates. The rotation angle calculating unit calculates a first candidate of the rotation angle θ from a first pair of the three output signals, examines whether the first candidate of the rotation angle θ is normal or not and calculates a next candidate of the rotation angle θ from another pair of the three output signals if the first candidate of the rotation angle θ is not normal, examines whether the next candidate of the rotation angle θ is normal or not, repeats the above two steps until a next candidate of the rotation angle θ is judged normal, and outputs one of the first and next candidates of the rotation angle θ as a formal rotation angle if it is judged normal.
