る回転数検出器。A multi-magnetized ring-shaped magnet is attached to a non-magnetic rotating body fixed to a rotating shaft, and a magneto-electric transducer is placed close to and facing the ring-shaped magnet on the fixed side, with the magneto-electric transducer being sandwiched between the rings. A rotation speed detector comprising a unipolar magnet on the opposite side of the shaped magnet, and a distance from the magnetoelectric conversion element to the magnetoelectric conversion element can be adjusted.
