STATOR COIL, STATOR CORE, AND ROTARY ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a stator coil whose coil end is downsized, a stator core, and a rotary electric machine.SOLUTION: A stator coil 138 to be inserted into the slot of a stator core is configured by a plurality of segment coils 28 composed of a conductor of a rectangular cross section molded into an U-shape that are connected in plural. The segment coil 28 has a connection 800 connected with the other segment coil at the end. At least one end of two segment coils sharing a connection in a radial direction, there is a corner 810. The corner is configured to be formed so as to protrude from the skirt of a mountain shaped weld zone toward an axial direction.SELECTED DRAWING: Figure 13
