``Conventional technology'' In a capacitor motor, in which an auxiliary winding and a capacitor are connected in series, and a main winding is connected in parallel, the windings are wound around a stator core that has many teeth protruding toward the inner diameter. It was something.

くないといった結果になった。
For this reason, attempts were made to reduce the number of slots, but there were many torque irregularities and vibrations, and this tendency became stronger when the gap between the stator and rotor was reduced to improve operating efficiency. There is a limit to how much can be reduced, and the result was that it was not desirable for an electric motor used in quiet equipment.

Therefore, as a conventional special motor configuration, the teeth, which were integral on the outer diameter side and protruded toward the inner diameter side, were formed into a star shape with the outer diameter side integrated and the outer diameter side open, so that the windings could be connected from the outer diameter side. Attempts have been made to make winding easier, and they have been effective in making winding easier.

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

For this reason, conventionally, this gap has been set to about 0.1 to 0.25 shoes.
