PRODUCTION METHOD FOR STATOR FOR ROTATING ELECTRICAL MACHINES

The last coil 3C to be placed on a tooth 21 is placed as follows. The last coil 3C is deformed into the shape of a rhombus to insert an outer peripheral end 321 of a one-side conductor portion 32A into a one-side slot 22A. The outer peripheral end 321 of the one-side conductor portion 32A is inserte...

Zusammenfassung:	The last coil 3C to be placed on a tooth 21 is placed as follows. The last coil 3C is deformed into the shape of a rhombus to insert an outer peripheral end 321 of a one-side conductor portion 32A into a one-side slot 22A. The outer peripheral end 321 of the one-side conductor portion 32A is inserted to the boundary position between an intermediate tilted side surface 212 and a base-end parallel side surface 213 in the one-side slot 22A. An outer peripheral end 321 of the other-side conductor portion 32B is inserted to the boundary position between an intermediate tilted side surface 212 and a base-end parallel side surface 213 in the other-side slot 22B to return the deformed last coil 3C to its original shape. The one-side conductor portion 32A and the other-side conductor portion 32B are simultaneously inserted into the one-side slot 22A and the other-side slot 22B, respectively.
