Abstract:
1. A rotating electric apparatus comprising: a stator having a stator winding comprising a plurality of coils connected in a plurality of slots formed in a stator iron core; and a rotor rotatably disposed in the inside of said stator; wherein, each pair of coils mutually connected in said stator winding is arranged in a fashion that a first coil of each said pair of coils has a top-side coil terminal at a top-side position of said slot, said top-side coil terminal being led out in the direction of a coil end of said stator winding; and a second coil of each said pair of coils has a bottom-side coil terminal at a bottom-side position of said slot said bottom-side coil terminal being led out in the direction of said coil end of said stator winding for connection to said top-side coil terminal; there is provided a coil terminal connection structure in which said top-side coil terminal and said bottom-side coil terminal are connected mutually across said coil end, and joint parts of said top-side coil terminal and said bottom-side coil terminal thus connected are bent so that said joint parts are disposed close to said coil end; each one of said top-side coil terminal and said bottom-side coil terminal is laid spiral-wise across said coil end to a position of the other one of said top-side and bottom-side coil terminals; side faces of joint parts of said top-side and bottom-side coil terminals are connected mutually in a fashion such that end faces of said joint parts of said top-side and bottom-side coil terminals are oriented in mutually opposite directions; and said joint parts thus connected are disposed close to said coil end.
