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.
