Embodiment approach 1

[0033] figure 1 is a diagram showing an application example of the rotating electrical machine according to Embodiment 1 of the present invention. The rotary electric machine 1 includes a first three-phase winding group 11 and a second three-phase winding group 21 . The first three-phase winding group 11 is connected to the first inverter 5 a via the current sensor 3 . The second three-phase winding group 21 is connected to the second inverter 5 b via the same current sensor 3 . The current sensor 3 is connected to the control circuit 7 . Furthermore, a rotation sensor 9 for detecting the rotation state of the rotating electric machine 1 is connected to the control circuit 7 .

[0034] Next, according to Figure 2 ~ Figure 4 Details of the rotating electrical machine of the first embodiment will be described. figure 2 It is a figure which shows the structure of a rotating electric machine seen from one side in the direction in which the rotating shaft extends. image 3 ...

Embodiment approach 2

[0059] Next, refer to Figure 5 and Figure 6 Embodiment 2 of the present invention will be described. In addition, the second embodiment is the same as the first embodiment except for the parts described below. Figure 5 and Figure 6 Respectively related to the second embodiment, and figure 2 and image 3 Figures of the same shape.

[0060] In the second embodiment, in short, the busbar units of one set of three-phase winding sets in the two sets of three-phase winding sets of busbar units are fixed to the following insulator, and the insulator is configured to be wound and installed with another set of The pole tooth portion of the winding wire of the three-phase winding group, the bus bar unit of the other three-phase winding group mentioned above is fixed to the following insulator, and the insulator is arranged on the side where the winding wire of the above-mentioned one group of three-phase winding group is wound and installed pole teeth. That is, the two busba...

Abstract

A rotating motor can easily carry out connection step of winding. In a coil part, multiple wires belonged to a two-group three-phase wire group are coiled and alternately arranged in the circumferential direction; wires belonged to a one-group three-phase wire group and wires belongs to another three-phase wire group are alternately arranged in the circumferential direction; the phase of each wire is different from the phases of neighbored wires; the first three-phase wire group is connected to a first bus unit, the second three-phase wire group is connected to a second bus unit, and the first bus unit and the second bus unit are arranged on opposite sides of a stator iron core in the axial direction.

Description

technical field [0001] The invention relates to a rotating electric machine. Background technique [0002] Conventionally, there is a dual three-phase motor in which two three-phase windings are provided in one motor (for example, refer to Patent Document 1). In this dual three-phase motor, the windings are connected on one side in the axial direction. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2013-236455 [0006] In the dual three-phase motor, there are windings for a total of six phases (U1, V1, W1, U2, V2, W2). When electrical connection is performed by welding or the like, jigs or the like for securing the positions of terminals to be connected tend to interfere with conductor members for electrically connecting windings and phases, thus requiring precise work. Contents of the invention [0007] The present invention has been made in view of the above circumstances, and an object of the presen...
