Rotating electrical machine

摘要

A rotating electrical machine includes a toric stator and a rotator located inside or outside the stator. The stator includes a plurality of teeth radially extending from the center of a circle of the stator with equal gap, and the plurality of coils arranged in order and in layers by the winding wire being turned a plurality of times around the circumference of each of a plurality of teeth. The number of turns of the two respective coils arranged on the circumference of the two adjacent teeth is different.

1. A rotating electrical machine comprising a stator and a rotator located inside or outside the stator,
wherein the stator comprises:
a plurality of teeth radially extending from the center of a circle of the stator; anda plurality of coils that are arranged in order and in layers by winding wire turn plural times around the circumference of the respective plurality of teeth, wherein the number of turns on each of two coils arranged on the circumference of two adjacent teeth is different, wherein a gap of two adjacent teeth is divided into half and the straight line radially extending from the center of the circle of the stator is defined as the gap centerline, wherein a position of the turn arranged closest to the gap centerline in one coil from among the two coils and the position of the turn arranged closest to the gap centerline in the other coil from among the two coils are not in an axially symmetric position with the gap centerline as the axis of symmetry, and wherein in the stator:
the plurality of coils configure a plurality of phases with alternately different phases having the adjacent plurality of coils among them as the same phase, andthe two coils are in the same phase and the total number of turns on the plurality of coils in the same phase is the same between a plurality of phases.
