Concentrated power-distribution member for concentrated winding motor

摘要

A concentrated power-distribution member for a concentrated winding motor including a ring-shaped busbar and a coil connection terminal formed in one-piece with the busbar to hold a coil winding end positioned in an inner side of the busbar. The coil connection terminal has an erected portion extending from the busbar in parallel with the center axis of the busbar and a pair of arms extending from the leading end of the erected portion toward a center axis. A pair of arms is constructed by a pair of wing portions that extend to both sides of the erected portion and are bent toward the center axis along a bending line parallel to the center axis. A coil end holding portion is provided in leading ends of the pair of arms. According to this construction, a dimension of the concentrated power-distribution member is reduced.

主权项

1. A concentrated power-distribution member for a concentrated winding motor, comprising:
a ring-shaped busbar having a center axis; and a coil connection terminal formed in one-piece with the busbar to hold a coil winding end positioned in an inner side of the busbar, wherein the coil connection terminal comprises:
an erected portion that extends from the busbar in parallel with the center axis, the erected portion having a leading end;a pair of arms extending from the leading end toward the center axis, the pair of arms being constituted by a pair of wing portions that extends from the leading end of the erected portion to both sides of a tangential direction of the busbar and are bent toward the center axis along a bending line parallel to the center axis; anda coil end holding portion provided in the leading ends of the pair of arms, and wherein a narrow portion is formed by deforming a middle part of the pair of arms to adjoin each other to cause the coil end holding portion to be provided in a leading end side of the pair of arms from the narrow portion and form a fork-shape.
