Title:
The stator of rotation electrical machinery
Document Type and Number:
Japanese Patent JP5988840
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a stator, of a rotary electric machine, that has favorable insulating properties.SOLUTION: A stator includes: a stator core having a plurality of slots; and stator coils that are provided in the respective slots. Each slot is provided with N segment conductors 28 (N is a positive even number). The stator coils are formed by connecting the segment conductors together through welds provided at respective conductor ends 28E of the segment conductors. At a first axial coil end 62, the conductor ends are arranged annularly in a circumferential direction so as to form N annular lines. At the first axial coil end, an insulating member is annularly interposed between at least a pair of annular lines. In the stator, the relationship between H and L is given by the following expression, H≥L≥H/2, where H(mm) represents the amount of protrusion of each slot liner from a stator end surface, and L (mm) represents a distance from the stator end surface to a point where each stator coil starts to bend.
