Revolving armature for rotary electric machinery |
摘要 |
A plurality of insulator-coated coils wound in slots of a magnetic core in multiple layers have end portions including at least contact portions without insulator coatings and connected to risers of a commutator, and adjacent portions next to the contact portions but out of the risers. A stepped portion is formed in at least one of the adjacent portion of an upper coil and the adjacent portion of a lower coil of the insulator-coated coils wound in multiple layers at a location where the upper coil and the lower coil face each other in crossing relation. A sufficient gap distance between the upper and lower coils is ensured at the location where the coils cross each other, and the productivity of revolving armatures is improved.
