In Fig. 3-Fig. 8 shown in, constitute stator winding 40 each wire 50 by having multiple slot incorporating section 51 and multiple rotating part
A piece continuous conductors of 52 is constituted, and the length of one is about 3m, and wherein, multiple slot incorporating sections 51 are the most linearly
Extension and the length direction along wire arrange at predetermined intervals, and adjacent slot incorporating section 51 is existed by multiple rotating parts 52 each other
The end side of slot incorporating section 51 is alternately connected with other end top-cross.Thus, as it is shown in figure 5, stator winding 40 has: by multiple
The slot incorporating section 51 of wire 50 at axial central part along the radially superimposed slot incorporating section laminated section of stator core 30
46 and in axial both sides from the axial both ends of the surface of stator core 30 towards the revolution of axially external multiple wires 50 prominent respectively
Portion 52 is along radially superimposed first of stator core 30 and the second end turn 47,48.
It addition, the rotating part 52 of wire 50 has a pair sector 56, they axial end face 30A with stator core 30
Extend substantially in parallel and the most adjacent with a pair slot incorporating section 51 connected by this rotating part 52.Thus, rotating part 52
Reduce from height h1 prominent for the end face 30A of stator core 30.Its result, the height of the first and second end turn 47,48
H1 reduces.
This patent effectively reduces stator height in the axial direction by such scheme so that the whole height of motor can
It is made less, when this motor is on electric vehicle, it is possible to effectively reduce the installing space of motor.
Owing to said stator winding 40 has a multiple slot incorporating section 51 being connected as a single entity and multiple rotating part 52, so,
After stator winding is shaped, it is impossible to it is installed on an all-in-one-piece stator core.In order to overcome the problems referred to above, should
In document (as shown in Figure 3 and 4), by by multiple iron core sectors 32 connecting by the way of the most adjacent and
Form stator core 30.It addition, stator core 30 has multiple slot 31, the footpath that this slot 31 is formed at stator core 30 is inside
Side face also configures the most at predetermined intervals.But, circumferentially the processing of the sector of sectional type, assembling the most more bother,
And it is difficult to ensure that the stability in the large after the assembling of multiple sector.
Summary of the invention
