Rotation angle detection device, rotating electric machine, and elevator hoisting machine

摘要

In the reference state of the rotation angle detection device, the first output winding having the number of turns Ai and the first output winding having the number of turns Aj smaller than Ai are included in the plurality of first output windings. The second output winding and the second output winding having the number of turns Bm smaller than Bk are included in the plurality of second output windings. The rotation angle detecting device is the same as the first output winding except that the number of turns Ai of the first output winding is the number of turns Ai ± a or the number of turns Aj of the first output winding is the number of turns Aj ± a. A configuration in which the number of turns of each of the first and second output windings is the same as that in the reference state, and the number of turns Bk of the second output winding is the number of turns Bk ± b, or the second output At least one of the configurations in which the number of turns of each of the first and second output windings is the same as that of the reference state except that the number of turns Bm of the winding is Bm ± b. I have.
