ROTATING ARMATURE, ROTATING ELECTRIC MACHINE, AND ROTATING ARMATURE MANUFACTURING METHOD

摘要

In a rotating armature, the numbers of teeth straddled by each of plural coil portions are all the same as each other, three. In plural windings that form the plural coil portions, three individual coil portions that, out of the plural coil portions, are disposed at uniform intervals around the circumferential direction of the armature core and are connected together in series are formed in each of the windings. In each of the windings including the three individual coil portions, one segment out of the plural segments is connected to another segment that has the same phase as the one segment out of the plural segments.

主权项

1. A rotating armature comprising:
an armature core including a plurality of teeth disposed at uniform angle intervals; a commutator that is disposed coaxially to the armature core and that includes a plurality of segments arranged around a circumferential direction; and a plurality of coil portions that are each wound a plurality of times straddling a plurality of individual teeth out of the plurality of teeth, and that are wound such that adjacent coil portions in the circumferential direction of the armature core partially overlap with each other; wherein,
a number of slots between the plurality of teeth is m×n, when m is the number of a plurality of magnetic poles provided at a periphery of the armature core, and n is a natural number;each of the plurality of coil portions straddles the same number of individual teeth;in a plurality of windings that form the plurality of coil portions, a plurality of individual coil portions that, out of the plurality of coil portions, are disposed at uniform intervals around the circumferential direction of the armature core and are connected together in series are formed in each of the windings; andeach of the windings including the plurality of individual coil portions is connected to one segment out of the plurality of segments, and to another segment that has the same phase as the one segment out of the plurality of segments.
