PROBLEM TO BE SOLVED: To provide a bus bar coupling unit for the stator of a rotary electric machine in which the size and cost of the stator can be reduced. SOLUTION: A coil is wound around each of tees 1 arranged annularly and each coil of each phase is connected by a bus bar 3(3a, 3b, 3c) made of a cable along the annular arrangement of the tees 1 thus obtaining the stator of a rotary electric machine. The stator is miniaturized by arranging the bus bars 3a, 3b, 3c and 3d of each phase in parallel on the side face of the tees arranged annularly. Each bus bar is formed by bundling arcuate rodlike wires 33<SB>1</SB>, 33<SB>2</SB>and 33<SB>3</SB>, equal in number to one half of the coils of each phase, in parallel and each wire is connected with a power supply terminal 6a, 6b, 6c at a position where all wires forming each bus bar are arranged. Each bus bar is contained in a holder 11 as a coupling unit. COPYRIGHT: (C)2008,JPO&INPIT
