Embodiment 1
[0075] First, use figure 1 and figure 2 The structure of the rotating electrical machine of the first embodiment will be described.
[0076] In the first embodiment, the rotating electric machine for driving the vehicle, which constitutes the driving power source of the vehicle together with the engine of the internal combustion engine, is mounted on a hybrid vehicle and driven by an inverter device that converts direct current supplied from a battery of an on-vehicle power supply into alternating current. The rotating electric machine has a rotor with built-in permanent magnets. The number of magnetic poles of the rotor is 8 poles, and the number of stator slots is 48. As the coil method of the stator winding, a synchronous motor using distributed winding will be described as an example.
[0077] In electric vehicles such as hybrid vehicles, a synchronous motor having a rotor with built-in permanent magnets and driven by an inverter device is advantageous in terms of high o...

[0133] Next, use Figure 13 ~ Figure 15 , the configuration of the rotating electrical machine of the second embodiment will be described. On the other hand, the overall configuration of the rotating electrical machine of the second embodiment is the same as figure 1 and figure 2 same as shown in .
[0134] Figure 13 It is an explanatory drawing of the winding method of the stator winding in the electric rotating machine of the second embodiment. Figure 14 It is a coil arrangement diagram at the time of winding the stator winding in the rotating electrical machine of the second embodiment. Figure 15 It is an explanatory diagram of the electrostatic capacity in the stator winding in the rotary electric machine of the second embodiment.
[0135] In the 2nd embodiment, with Figure 8 , Figure 9 , Figure 11 As explained in , one stator winding, for example, the number of coils of the stator winding U1 is 12T.
[0136] In the second embodiment, after the coils of one...

[0150] Next, use Figure 16 , the configuration of the rotating electric machine of the third embodiment will be described. On the other hand, the overall configuration of the rotating electric machine of the third embodiment is the same as figure 1 and figure 2 same as shown in .
[0151] Figure 16 It is a layout diagram of the coils when the stator winding is wound in the rotating electrical machine of the third embodiment.
[0152] In the 3rd embodiment, with Figure 8 , Figure 9 , Figure 11 As described in , one stator winding, for example, the number of coils of the stator winding U1 is 12T for description. In the third embodiment, after the coils of one stator winding are divided into four coil groups, they are sequentially wound on the coil frame VL by an automatic winding machine (4-divided winding = 2 reciprocating windings). That is, in this example, if the number of coils in one stator winding is 12T, the first coil group of 1T to 3T, the second coil gro...
