The purpose of the distributed winding of the winding as described above is to reduce spatial harmonics of the magnetic field that cause a reduction in thrust in a linear induction motor. but,
In conventional linear induction motors, the diameter of each subcoil is the same, so it is necessary to overlap each side of the subcoils by the number of phases x the number of slots per pole and slots in both the left and right and top and bottom directions. There was a problem in that the protrusion of the capacitor became large, the leakage inductance increased, and the power factor decreased.

FIG. 1 shows an example of a winding used in the present invention, and in this embodiment, the coil unit 20 consists of five subcoils 11. Each of these subcoils 11 is made by winding a conductor multiple times and applying insulation coating, and each has a different winding diameter.
As shown in FIG. 1, by fitting the subcoils 11 with smaller diameters inside the subcoils 11 with a larger diameter, the subcoils 11 are arranged in the same plane.
また、各サブコイル１１の巻線が継ながつてい

鉄心１４は従来のものと全く同じもので、複数の
スロツト１５が一定のピツチで形成されている。 In addition, it goes without saying that the windings of each subcoil 11 are connected, and one end 12 is drawn out from a part of the outside of the largest diameter subcoil 11 that is the outer side, and the smallest diameter subcoil that is the inner side. The other terminal 13 is pulled out from a part of the inside of the terminal 11.
The iron core 14 is exactly the same as the conventional one, and has a plurality of slots 15 formed at a constant pitch.
上記の鉄心１４に第１図に示すサブコイル１１

Further, the left side of the subcoil 11 having the second largest diameter is fitted into the second slot 15 from the left, and the right side is fitted into the 19th slot 15 from the left.
こうして、サブコイル１１の径が小さくなるに
従つて、サブコイル１１の左辺がはまるスロツト

相の最小の径のサブコイル１１の左辺は右から５
番目のスロツト１５にはまり、右辺は左から16番
目のスロツト１５にはまる。 In this way, as the diameter of the subcoil 11 becomes smaller, the slot 15 into which the left side of the subcoil 11 fits becomes closer to the slot 15 into which the right side fits in, and U 1
The left side of the subcoil 11 with the smallest diameter of the phase is 5 from the right.
The right side fits into the 16th slot 15 from the left.

Insert the right side of the subcoil 11 with the smallest diameter into the slot 15.
V1相の各サブコイル１１も同様にその左辺と
右辺を左から11番目から15番目のスロツト１５

次はめ込む。 Similarly, the left and right sides of each subcoil 11 of V1 phase are connected to slots 15 from the 11th to the 15th from the left.
and insert them into the 30th to 26th slots 15 from the left.
つぎに、U2相、W2相、V2相のサブコイル１１

The left side of each phase is the U 1 phase and W 1 phase .
Phase, V 1 Slot 1 where the right side of phase is fitted
5, so there are two layers, top and bottom. Thereafter, the subcoils 11 are fitted into each slot 15 in the same manner.
また、上記のように各スロツト１５にはめ込ん

辺をゆるやかに下方へ曲げ、右辺を大きく下方に
曲げる。 Further, each subcoil 11 fitted into each slot 15 as described above has its left side bent gently downward, and its right side bent largely downward, as shown in FIGS. 2 and 3.
なお、結線および通電方式などは公知のリニア
インダクシヨンモータと同じである。 Note that the wiring and energization method are the same as those of known linear induction motors.

As described above, a major feature of this invention is that the winding diameters of the plurality of subcoils belonging to the same phase are made to be different from each other so that they can be fitted together on the same plane. That is, in the case of this invention, the second
As is clear from Figures 3 and 3, only subcoils of the same phase overlap in the inner and outer directions, so if there are 5 subcoils per phase, the amount of protrusion from the iron core is equal to 5 subcoils on one side. Become. On the other hand, in the case of conventional coil units as shown in FIGS. 6 and 7, if there are five subcoils per unit, the overlap in the inner and outer directions is 15 on one side.

有の効果がある。 In addition, in this invention, both sides of one end of each subcoil are bent gently downward, and both sides of the other end are bent significantly downward, so the amount of protrusion of the subcoil from the iron core is reduced, and leakage inductance is reduced. , the power factor improves. Further, since the dimensions of the coil unit are reduced, the required amount of conductor used in the winding is reduced, resulting in a unique effect such as weight reduction.
