Patent ID: 7498713

Claim:
A dynamoelectric stator comprising: an annular stator core in which a plurality of slots opening radially inward are formed circumferentially; and a stator winding installed in said stator core, wherein: a sheet-shaped varnish supporting member is disposed so as to be placed in close contact with a radially-outermost surface of a coil end group of said stator winding around an entire circumference; a radially-innermost surface and an axial end surface of said coil end group are exposed around said entire circumference; a varnish is applied to said coil end group; an insulator is mounted in each of said slots so as to be interposed between a slot-housed portion of a wire constituting said stator winding and an inner wall surface of said slot and so as to project outward from said slot and cover a root portion of a coil end of said wire; and said varnish supporting member is disposed so as to be adjacent to an end of said insulator projecting from said slot relative to an axial direction of said stator core.
