Problems solved by technology

[0005] However, in a rotating electrical machine in which double-layered overlapping coils are arranged in slots as in Japanese Patent Laid-Open No. 2009-195004, there is a problem in that the double-layered overlapping coils included in the coil assembly of each phase When the phases are assembled in the slots one by one alternately in the order of the phases, due to the different assembly methods, the connecting wires connecting the phases of the double-layer overlapping winding coils will be braided (for example, in the case of three phases, the three-phase connecting wires will be twisted. twisted into a three-strand braid)

[0033] (Structure of rotating electrical machine)

[0034] refer to Figure 1 to Figure 6 , the structure of the rotating electric machine 100 of the first embodiment will be described. in, figure 2 A single-phase coil 30 assembled in the stator core 21 is shown.

[0035] In addition, in the specification of the present application, "axial direction" refers to a direction (X direction, refer to figure 1 , Figure 9 Wait). In addition, the "circumferential direction" refers to the circumferential direction of the stator 20 (A1 direction or A2 direction, refer to figure 1 ). In addition, the "inner diameter side" refers to the direction toward the center of the stator 20 in the state assembled in the rotating electric machine 100 (R1 direction, refer to figure 1 ). In addition, "outer diameter side" refers to a direction (R2 direction, refer to figure 1 ).

[0036] like figure 1 As shown, the rotating electric machine 100 includes a rotor 10 . A plurality of permane...

Abstract

A method for producing a stator comprises a step wherein with a plurality of coil portions, which include a first coil portion, connected by means of a jumper wire to each phase, the coil portions aremounted to slots by means of rotation centered on the jumper wire.

Description

technical field [0001] The present invention relates to a method of manufacturing a stator and a method of manufacturing a rotating electrical machine. Background technique [0002] Conventionally, there is known a rotating electric machine in which double-layered overlapping winding coils are arranged in slots, in which one of a pair of slot accommodation portions arranged in the slots of the coils is arranged on the outer diameter side of the slots, and The other of the pair of socket housing parts is disposed on the inner diameter side of the socket. Such a rotating electric machine is disclosed, for example, in JP-A-2009-195004. [0003] Here, when a coil assembly in which a plurality of double-layer overlapping winding coils are connected by connecting wires is arranged in a slot in multiple phases (for example, three phases), the double-layer overlapping winding contained in the coil assembly of each phase The winding coils are assembled in the slots one by one alter...
