For this reason, attempts have been made to reduce the number of slots, but there are many torque irregularities and vibrations, and this tendency becomes stronger when the air gap between the stator and rotor is reduced to improve operating efficiency. The result was not desirable for electric vehicles.

そこで、従来外径側が一体で内径側へ突出していた歯部

However, if a yoke that forms a magnetic path between the teeth is installed on the outer diameter side after winding the star-shaped teeth, the windings are likely to be damaged, resulting in poor insulation. A failure such as a disconnection has occurred. ``Under these conditions, when the power supply voltage is high, the winding becomes thinner, so the number of defects increases rapidly.
This had the problem of being impractical.

However, although reducing the gap improves efficiency, it also makes machining difficult, and because the magnetic flux is unevenly distributed in the southern part, sliding motion tends to occur and noise tends to increase.

このため、従来は、この空隙を0.1〜0.25m程度
