摘要： First to fourth magnetic detection units (22-25) are arranged in opposition to a multipole magnetized surface (21a) of a multipole magnet (21) of a magnetic encoder (17). The first and second magnetic detection units (22, 23) are placed on positions separated from each other by 180 degrees on the periphery of the center of the multipole magnet and output an A-phase signal and a B-phase signal. The third and fourth magnetic detection units (24, 25) are placed on positions separated from each other by nearly 180 degrees on the periphery of the center of the multipole magnet and output an A-phase reverse signal and a B-phase reverse signal. Detection signals of the same phase are synthesized and averaged, and consequently a detection error generated by an outer magnetic flux extending in the diameter direction of the multipole magnet can be removed. The signal obtained by synthesizing the detection signals of the same phase and averaging the same and the reverse signal of a signal obtained by synthesizing reverse signals of the reverse phase and averaging the same are synthesized and averaged, and consequently the detection error generated by the outer magnetic flux radially extending in one direction along the radius direction of the multipole magnet can be removed.

摘要： In an actuator (1) in which an angle detector (13) of a magnetic encoder for detecting the rotational position of a motor (3) is incorporated inside a wave reduction gear (5), detection signals from Hall elements (11a, 11b) of the angle detector (13) are transmitted via sensor lead wires (17) that have been brought out through wiring holes (36a, 33a, 35a, 37a) formed inside the motor (3) to a sensor signal converter board (14) disposed on the rear end side of the motor. Since the wiring is not required to be brought out to the exterior, indirectly routed along the exterior of the motor (3), and brought out to the rear side thereof, the wiring is not mechanically damaged and can be brought out with the shortest possible wiring distance, and the effect of electromagnetic noise can be reduced.

摘要： In the magnetic absolute encoder, an ordinary operating circuit and an ordinary/backup operating circuit are actuated during ordinary operation in which power is supplied from the ordinary operating power supply; the single-rotation absolute value (1) and single-rotation absolute value (2) detected by these circuits are compared by the abnormality diagnosis circuit, and the presence or absence of an abnormality is automatically judged During backup in which the ordinary operating power supply is interrupted, only the low-power-consumption ordinary/backup operating circuit is actuated, and the multiple-rotation value (2) is detected At the point in time at which the system is returned to ordinary operation, the multiple-rotation value setting circuit sets the multiple-rotation value (2) as the multiple-rotation value (1) of the ordinary operating circuit. As a result, the calculation operation of the multiple-rotation value (1) can be restarted.
