摘要： PROBLEM TO BE SOLVED: To provide a magnetic induction type rotary position detector capable of reducing the detection error caused by the leak of magnetic flux to perform high accurate detection.
SOLUTION: In the magnetic induction type rotary position detector 10, secondary side induction coils 17As-17Hs and primary side exciting coils 18A-18H are arranged to a stator 11. Compensation coils 19As-19Hs are arranged at the positions corresponding to the secondary side induction coils 17As-17Hs of a sine phase and these secondary side induction coils and the compensation coils are connected in series. The secondary side induction coils and the compensation coils are connected in series even on the side of a cosine phase in the same way. By appropriately setting the winding direction and winding number of the compensation coils, the error component caused by the leaked magnetic flux or the like contained in the detection signals obtained from the secondary side induction coils of respective phases can be reduced and, by this constitution, the absolute accuracy of the magnetic induction type rotary position detector 10 is improved.

摘要： PROBLEM TO BE SOLVED: To propose a reliable magnetic absolute encoder for implementing a detection operation at a high speed and high precision during a normal operation, and for continuing the detection operation at a low power consumption during a backup operation.
SOLUTION: In the magnetic absolute encoder 1, power is supplied from a normal operation power supply 8, and a normal operation circuit 5 and a normal/backup operation circuit 6 are operated during the normal operation. An abnormality diagnosis circuit 10 compares single-rotation absolute values (1), (2) detected by them, and self-diagnoses the existence of an abnormality. The normal operation power supply 8 is interrupted, and only the low-power-consumption normal/backup operation circuit 6 is operated so as to detect multiple-rotation value (2) during the backup operation. When the normal operation is recovered, a multiple-rotation value setting circuit 12 sets the multiple-rotation value (2) as the multiple-rotation value (1) in the normal operation circuit 5. An operation for calculating the multiple-rotation value (1) is resumed.

摘要： PROBLEM TO BE SOLVED: To provide a method for attaching a stator consisting of a plurality of split cores to a motor frame under such a state as respective split cores are coupled precisely. SOLUTION: A stator attaching tool 10 capable of attraction holding split cores 4 by magnetism is prepared, each split core 4 is fixed to its circular outer circumferential surface 11a and attraction held in place. A tubular stator 1 where respective split cores 4 are coupled precisely whitout causing misregistration can thereby be constituted by simple work. The stator 1 under that state is inserted, as it is, into the motor frame 3 and bonded to the inner circumferential surface thereof. Consequently, a stator 1 comprising split cores 4 coupled tubularly under a state free from misregistration can be attached easily to the inner circumferential surface 3a of the motor frame 3.
