On the other hand, due to the rotation 0 due to this light, the 24th rotation of the electric power is suppressed, so that the addition at this frequency and wave number is suppressed, and the electromagnetic noise is significantly reduced.
- the rotation 0 due to this light has the effect of reducing. In detail, it increases with the magnetic flux and becomes a factor to decrease the ta factor. In the future, the number of different-phase tees was higher than the number of common-phase tees because the number of different-phase tees was relatively high (area).
- the rotation 0 due to this light is adjusted to one even in the magnetic flux degree by the magnetic flux generated in the different phase and the same phase. Therefore, it is reduced to the in-phase tee that occurs in the out-of-phase tee. As a result, it is less than the conventional machine that occurs in 52 stators.
