このような視点からは、殆ど完成されたものといってよ

その新しい発想とは、何らかの方法で磁束の空間高調波
成分を打ち消し、除去することである。The new idea is to somehow cancel out and remove the spatial harmonic components of magnetic flux.
（問題点を解決するための手段）
本発明の２回転磁界中の空間高調波磁束の除去方法は２
次の通りである。(Means for solving the problem) The method for removing spatial harmonic magnetic flux in a two-rotation magnetic field according to the present invention is as follows.
It is as follows.
（イ）回転磁界中に含まれている。除去したい第ｎ次の
空間高調波磁束成分を検出するため、基本波磁束極数の
ｎ倍の極数をもった巻線を、この回転磁界中に配置する
。(a) Included in a rotating magnetic field. In order to detect the n-th spatial harmonic magnetic flux component to be removed, a winding having a number of poles n times the number of poles of the fundamental wave magnetic flux is placed in this rotating magnetic field.
（υ）この第ｎ次の空間′ＢＴ！Ａ波磁束成分検出巻線
を短絡する。(υ) This nth space 'BT! Short-circuit the A-wave magnetic flux component detection winding.
（作用）
回転磁界の基本波磁束の極数をＰとすると、第ｎ次の空
間高調波磁束の極数はｎＰとなるから。(Function) If the number of poles of the fundamental wave magnetic flux of the rotating magnetic field is P, then the number of poles of the nth spatial harmonic magnetic flux is nP.
ｎＰ極の巻線に＋ｆ ｎ次の空間高調波磁束成分のみに
よって、基本波周波数のｎ倍の周波数をもった電圧が誘
起される。従って、この巻線を短絡すると、基本波磁束
のｎ倍の高調波起磁力が発生し。A voltage having a frequency n times the fundamental wave frequency is induced in the nP-pole winding only by the +f nth order spatial harmonic magnetic flux component. Therefore, when this winding is short-circuited, a harmonic magnetomotive force that is n times the fundamental wave magnetic flux is generated.
この起磁力が回転磁界中のｎ次の空間高調波磁束成分を
打消す。このため回転磁界中に含まれている第ｎ空間高
調波磁束が除去され２回転磁界の空間分布波形は正弦波
に近づくことになる。This magnetomotive force cancels the nth order spatial harmonic magnetic flux component in the rotating magnetic field. Therefore, the n-th spatial harmonic magnetic flux contained in the rotating magnetic field is removed, and the spatial distribution waveform of the two-rotating magnetic field approaches a sine wave.

In addition to generating a rotating magnetic field by applying distributed, full, and overlapping windings (hereinafter referred to as three-phase main windings), the grooves in the stator core are used to generate the third and fifth In the case where a spatial harmonic magnetic flux removal winding is installed), an example will be shown below.

。Looking at the induced voltage waveform in FIG. 3, it can be seen that the spatial magnetic flux distribution waveform of the rotating magnetic field due to the three-phase main winding is far from a sinusoidal waveform, and even pulsates depending on the location. On the other hand, looking at the induced voltage waveforms in Figure 4, there is almost no difference in the induced voltage waveforms of any coil, and they all have a distribution close to a sine wave, indicating that the effect of the spatial harmonic flux elimination winding is very large. I understand.

るので好都合である。In order to cancel the magnetomotive force caused by the current flowing through the spatial harmonic flux elimination winding, the excitation current increases in motors, etc., but generally the number of turns of the spatial harmonic flux elimination winding is three-phase. Since the number of turns is smaller than the number of turns for main tightening, the rate of increase in the excitation current is not only very small, but this increase in current has the effect of improving the waveform distortion of the excitation current, which is advantageous.

効果が期待できるものである。From the above, it can be seen that if a spatial harmonic magnetic flux elimination winding is applied to an induction motor or a synchronous motor, the magnetic flux distribution waveform of the two-rotation magnetic field becomes closer to a sine wave, and the torque characteristics are improved. It can be seen that by applying , it is possible to make the visiting voltage waveform even closer to a sine wave. Moreover, this spatial harmonic magnetic flux removal winding can be expected to have a great effect in any device other than a motor or a generator that utilizes a two-rotation magnetic field.
