で代表するものとする。 Now, corresponding to these phase bands 1a and 2a, a magnetic field distribution is generated as shown in the steps from mode to mode shown in diagram b, and the magnetic field distribution changes the magnetomotive force fluctuation during one cycle by 60 degrees in electrical angle. This shows a state in which the magnetic field generated by LIM1 moves in the direction of arrow A and the magnetic field generated by LIM2 moves in the direction of arrow B, which is opposite to the direction of arrow A. It is assumed that the maximum magnetomotive force values F 1 and F 2 of LIMs 1 and 2 are equal. In addition, in general, in a moving magnetic field generator, the windings are distributed and wound, so the distribution of magnetomotive force changes in a fine step-like manner, but to simplify the drawing, one rectangular wave is used for each phase band. shall be representative.

(ハ) 考案が解決しようとする問題点
ここに、磁界の強い部分と弱い部分が生じるの
で、次のような問題点があつた。(c) Problems that the invention aims to solve Because there are strong and weak magnetic fields, the following problems arose.
(1) LIM１と２の極数が同一の場合に移動磁界
方向を逆にすると、１相だけが他の相と異なり
電流のアンバランスが生じ、コイルの利用率を
低下させ、無用な銅損失を発生させる。(1) If the number of poles of LIM1 and LIM2 is the same, and the direction of the moving magnetic field is reversed, only one phase will be different from the other phases, resulting in an unbalanced current, reducing the coil utilization rate and causing unnecessary copper loss. to occur.
(2) LIMまたは円弧状の誘導電動機は互いに逆
方向の移動磁界を発生するため、相手の磁束に
より誘起する電圧は対称座標法でいう逆相電圧
であつて、互いに相手のコイルに逆相電流を流
すこととなり、無用の銅損失を発生させる。(2) Since LIM or arc-shaped induction motors generate moving magnetic fields in opposite directions, the voltage induced by the magnetic flux of the other is an anti-sequence voltage in the symmetric coordinate method, and the opposite-sequence current flows in the coils of the other. This causes unnecessary copper loss.
(3) 一定場所に磁界の強い部分が集中するので、

に支持されている。 In FIG. 1, among a set of circular arc-shaped induction motor 11 and circular induction motor 12 as a moving magnetic field generator, the circular induction motor 11 is fixed, and the circular induction motor 12 is rotatable. It is arranged like this. That is, the annular induction motor 12 is supported so as to be rotatable as shown by the arrow c by providing, for example, a roll (not shown) inside.
次に、その作用を第２図ａ，ｃに基づいて説明

愛する。 Next, its operation will be explained based on FIGS. 2a and 2c. The magnetic field distribution in FIG. 2b is similar to that shown in FIG. 4b, so its explanation will be omitted here. Furthermore, when compared with the LIM shown in Figure 3a, the moving magnetic field generator of this embodiment differs in that one side rotates, but structurally it is similar to the LIM when extended horizontally, and it rotates. Explanation related to this is omitted because it is not related to the straight line invention.
第２図ａに示す相帯１ａは第４図ａに示す相帯

Further, the same applies to the phase belt 1a and the annular phase belt 2c facing each other. In such a phase band arrangement, while the phase band LIM2c is changed by 60 degrees in electrical angle (if the frequency is f, it is 1/6f in time), the phase band size of one phase is changed counterclockwise by 1/2. The resultant magnetic field distribution when rotated is the second
As shown in Figure c, when compared with Figures 4c and 5b, it can be seen that the maximum part of the magnetic flux density moves to the left with time.

とができる。 Therefore, the rotation direction of the part with a strong magnetic field can be unidirectionally rotated or reversed, and the speed can be set periodically or arbitrarily, so that the conventional phenomenon of reverse phase current flowing and phase current imbalance can be avoided. , copper loss is reduced. Additionally, electrically switching the arrangement of the phase bands makes the distribution of the magnetic field uneven, making it difficult to handle by installing partitions inside the container, or requiring complex mechanisms such as mechanically moving the container. This makes it possible to avoid stagnation and inactivity of the working pieces and objects to be processed in the container, and to perform efficient grinding, mixing, and agitation.
