Rotary electric machine and method for connecting stator conductors
A rotary electric machine having improved coil connection reliability, simplified coil end processing steps and improved workability based on an improved components mounting method is to be provided. Flat type conductors are inserted in a stacked state into each of slots formed in a stator core, and a side face of a preceding-stage winding terminal end and a side face of a succeeding-stage winding start end in the flat type conductors are lapped and connected to constitute an assembly of stator coils. The stator coil assembly comprises plural coil groups, and one electrode is connected to one conductor end in the coil groups, while another electrode is moved in a successive manner to connect preceding- and succeeding-stage winding terminal and start ends of the conductors. Further, an insulating ring with crossover conductors laid thereon is combined with such stator coil assembly to connect winding terminal and start ends of the stator coil assembly, thereby constituting a predetermined winding circuit.
