STATOR AND METHOD OF MANUFACTURING STATOR

摘要

In a stator, segment coils each consisting of a pair of straight portions connected with a connecting portion in a U-like shape are set in slots of a stator core. Each straight portion has distal end parts protruding on an opposite side to the connecting portions. The distal end parts in odd-numbered positions from an outer or inner circumferential side in a radial direction are twisted in one direction and shaped radially outward and the distal end parts located in even-numbered positions are twisted in an opposite direction to the one direction and shaped radially inward to be joined to each other on the same circumference by welding.
