摘要： A rotation number detector according to an embodiment is a rotation number detector that detects the number of rotations of a magnet attached to a rotating body by using a power generation unit. The power generation unit includes N (N is a natural number equal to or larger than 1) power generation elements, each including a magnetic wire in which magnetization reversal occurs due to a large Barkhausen effect and a pickup coil that is wound around the magnetic wire. The magnetic wire is longer than a wound portion of the pickup coil in an extension direction of the magnetic wire of the power generation elements. The magnetic wire is set above a rotation center of the magnet.

摘要： An encoder includes a first multiple rotation counter that generates first multiple rotation data using a rotation signal indicating one rotation of a rotational shaft of a motor, a second multiple rotation counter that generates second multiple rotation data using the rotation signal, a first cumulative-number calculation unit that calculates first accumulated multiple rotation data using an angle signal indicating a rotational angle of the rotational shaft, a second cumulative-number calculation unit that calculates second accumulated multiple rotation data using the angle signal, and a first comparative diagnosis unit that diagnoses whether the encoder has a fault by performing a comparison to determine whether the first multiple rotation data, the second multiple rotation data, the first accumulated multiple rotation data, and the second accumulated multiple rotation data are a same value.

摘要： In an elevator car position detection device, a magnetic field generator generates an eddy current magnetic field on an identification member, and a magnetic field detector detects the eddy current magnetic field generated on the identification member. The identification member includes a plurality of conductors which are continuously arranged along an ascending and descending direction of a car, and are relatively different in a plate thickness with respect to a skin depth of an eddy current generated by the magnetic field generator on the identification member. A shape of at least a part of a boundary between the adjacent conductors is a straight line or a curve tilted with respect to a direction orthogonal to the ascending and descending direction of the car.
