ROTARY ELECTRIC MACHINE STATOR AND MANUFACTURING METHOD OF SAME

摘要

A rotary electric machine stator includes: a stator core including slots; a stator coil wound around the stator core by joining end portions of a plurality of segment conductors placed to be inserted into each of the slots; and an insulating layer (54) provided around the end portions including a joining portion at the end portions of the plurality of segment conductors. The segment conductor is constituted by an electric conductor (44) and an insulation coating (46) that covers the electric conductor (44). A conductor exposed portion (50) in which the insulation coating (46) is removed is formed in each of those end portions (38) of the segment conductors which are joined to each other. The insulating layer (54) is formed to be attached onto an insulating member (52) that covers a stepped portion (48) formed in a boundary between the insulation coating (46) and the conductor exposed portion (50).
