次に本発明の天7i!i例を第2図に基いて説明するが
、まず本発明のモーターの構成を説明する。Next, the Ten7i of the present invention! Example i will be explained based on FIG. 2, but first the configuration of the motor of the present invention will be explained.
本発明のモーターはS極、N極2つの永久磁石1.2と
回転子3で構成する。The motor of the present invention is composed of a permanent magnet 1.2 with two S and N poles and a rotor 3.
〈イ〉 回転子3は中空筒体でその筒体31の軸部から
それぞれ120°の角度で、筒体内壁に尚接するまでの
ばした3枚の板状の電機子32〜34を設ける。<A> The rotor 3 is a hollow cylinder, and three plate-shaped armatures 32 to 34 are provided at an angle of 120 degrees from the shaft of the cylinder 31 until they touch the inner wall of the cylinder.
つまり、前記した従来のモーターの傘部の先端全延長し
、各傘部がわずかの空隙全もって対向することになる。In other words, the tips of the umbrella parts of the conventional motor described above are fully extended, and each umbrella part faces each other with a small gap between them.
1枚の電機子には、巻線35が同一方向にまかれ、更に
巻線の両先端全整流子に接続するが、以上は従来のモー
ターと同様である。A winding 35 is wound in the same direction on one armature, and both ends of the winding are connected to all commutators, but the above is the same as in a conventional motor.
〈口〉 磁石
S極、N極の永久磁石1..2i、回転子3の断面に直
交する向きに、回転子全中間において一定の間隔をとっ
て相対向して設置する。<Mouth> Permanent magnet with S pole and N pole 1. .. 2i, they are installed facing each other at a constant interval in the entire middle of the rotor in a direction perpendicular to the cross section of the rotor 3.
この点も従来のモーターと同様である。This point is also similar to conventional motors.
ぐ・〉 発生トルク
以上の構成のモータを用いて発生するトルクを比較した
。We compared the torque generated using a motor with a configuration that exceeds the generated torque.
その結果市販のモーターを改良して各傘部の端を、相互
にできるぞけ延長して接近させたモーターは、改良前の
モーターに比較して約3割程度もトルクが上列すること
がわかった。As a result, a commercially available motor was modified to extend the ends of each umbrella part as close as possible to each other, resulting in a motor with about 30% more torque than the motor before the improvement. Understood.
次に本発明のモーターにおいてトルクが増大した原理を
考えてみる。Next, let us consider the principle by which the torque is increased in the motor of the present invention.
従来のモーターは板状部材に巻線をコイル状に巻いた構
成をなし、従って鉄心をもつソレノイドの状態になると
考えられる。この場合供電時においては棒磁石となり先
端に、即ち傘部の外周側に磁極が現れる。A conventional motor has a structure in which a winding wire is wound in a coil around a plate-shaped member, and therefore it is considered to be in the state of a solenoid with an iron core. In this case, when power is supplied, it becomes a bar magnet and a magnetic pole appears at the tip, that is, on the outer circumferential side of the umbrella.
モーターの回転理論は磁界内にある導電体は磁力線と導
電体電流の両者直角方向に力を受けるというフレミング
の法則によるものである。The theory of rotation of a motor is based on Fleming's law, which states that a conductor in a magnetic field is subjected to a force perpendicular to both the magnetic field lines and the conductor current.
ところが本発明は導磁率の大きい環状部材にょ3−
って態々導電体部に入る磁力線を遮断する構成を々して
いる。However, the present invention has a configuration in which the annular member with high magnetic permeability blocks the lines of magnetic force that enter the conductive portion.
従ってフレミングの法則では説明はできない。Therefore, Fleming's law cannot explain it.
そこで本発明ではその回転の理由として一つの仮説を設
け、これによる力も加わるものと考える。Therefore, in the present invention, one hypothesis is established as the reason for the rotation, and it is assumed that the force due to this is also applied.
即ちその仮説とは傘部の外周面に現れた磁極と永久磁石
間に生じる吸引及び反撥の力によってモーターは回転す
ると考えるものである。That is, the hypothesis is that the motor is rotated by the attraction and repulsion forces generated between the magnetic poles appearing on the outer peripheral surface of the umbrella and the permanent magnets.
この点から考えて本発明は傘部相互間を接近させ、その
結果磁力線の数を増加させ磁極の゛強化させようとする
ものである。Considering this point, the present invention attempts to bring the umbrella parts closer to each other, thereby increasing the number of magnetic lines of force and strengthening the magnetic poles.
すなわち磁極の強さは導電体の巻回数と電流の大きさに
関係し、板状部材はコイル内を通る磁力線の数を増大さ
せている。That is, the strength of the magnetic pole is related to the number of turns of the conductor and the magnitude of the current, and the plate-like member increases the number of lines of magnetic force passing through the coil.
そして磁力線の数が増すと磁極の強さが増すことから本
発明は強化された傘部材の磁極と磁石の磁界の相互作用
によってトルク増をはかろうとするものである。Since the strength of the magnetic poles increases as the number of magnetic lines of force increases, the present invention attempts to increase torque through the interaction between the strengthened magnetic poles of the umbrella member and the magnetic field of the magnet.
次に本発明のモーターの回転に際し−での特徴を4− 従来例と比較しながら図面と共に説明する。Next, when rotating the motor of the present invention, the characteristics in - are 4- This will be explained with reference to the drawings while comparing it with a conventional example.

2 and C3 are each n independently magnetized by power supply.

その磁化状態はデルタ−結線のモーターにおいては2個

さ几る。In a delta-connected motor, the magnetization state is two north poles and one south pole, or two south poles and one north pole.

り、図に示す矢印方向2つの磁気回路を形成している。The figure shows the magnetization state of two N poles and one S pole, forming two magnetic circuits in the direction of the arrows shown in the figure.

nるものと考えらnる。A circuit consisting of one circuit C2 and C3 is considered to have the characteristics of a solenoid P with an iron core. That is, it is thought that a deformed magnet is formed, and the polarities of N and S appear at the tips of C3 and C2.

よって形成する2つの磁気回路は僅かの磁気スリットを

意味ではなく、磁気的に遮断されているという意味であ
る。<Mouth> On the other hand, in the present invention, as shown in FIG. 4, the umbrella parts 03+02 and 01. C2 forms two magnetic circuits as in Fig. 3. However, in particular the two magnetic circuits formed by the inserts T have only a few magnetic slits. The term "magnetic slit" as used herein does not mean a mere gap, but means that it is magnetically blocked.

3図と比較して更に増加する。即ち磁力線の数は増大し
、トロイドが特殊な変形の鉄心を持つため、傘部O1,
C2+ 03の先端では第3図と比較して更に強い磁化
が得らn2る。Basically, it forms an annular shape called a toroid. In this case, the magnetic flux density within the core increases further compared to FIG. That is, the number of magnetic lines of force increases, and since the toroid has a specially deformed iron core, the umbrella part O1,
At the tip of C2+ 03, even stronger magnetization is obtained compared to FIG. 3 n2.

き(第7図)。Next, if the space S between the umbrella parts is narrower, a larger rotational force can be obtained with the same current value.1. The basis for this will be explained using a calculation formula. (
Example: Houka Publishing University Course Physics Essay Revised Edition Vol. 2, pp. 142-144) "When a long iron core is bent into an annular shape and the tip is completely closed and has a gap 1" (No. 7 figure).

+μr T) increases twice.
たとえば、1/1000の空隙があっても、必要な起磁
力は2倍となり、そ几だけ多量の起磁力を消費する。For example, even if there is a gap of 1/1000, the required magnetomotive force will be doubled, and a large amount of magnetomotive force will be consumed.
従って相対的に小さい電流で大きい起磁力を得るために
はbはOであ几ばよい。Therefore, b should be O in order to obtain a large magnetomotive force with a relatively small current.
しかしb−0ではS、N極が生じない。However, in b-0, S and N poles do not occur.
そのため極を生じさせ、かつ大きい起磁力を得るために

ことを要する。Therefore, in order to generate a pole and obtain a large magnetomotive force, it is necessary to take a value that is the minimum within the processable range and is not zero.

(Fig. 6) (c) The inter-umbrella space between each umbrella portion is magnetically connected with a fitting member made of a material with excellent magnetic properties, such as silicon steel, and the fitting member is In the middle or with the fitting member 1
A magnetic slit is provided between the two umbrella parts.

Alternatively, a ring made of silicon steel or the like is fitted around the outer periphery of the cap part around the diameter of the winding wire, the ring and the cap part are glued together, and finally the ring is cut to form a slit.

うになるので次のような効果を期待する事ができる。Other Examples Although a three-pole motor has been described above, the present invention can also be applied to a motor that increases torque by using four permanent magnets, with the N pole being N, S, N, and S. Since the motor of the present invention to which the idea of the above can be applied is as explained above, the following effects can be expected.

的に確認さnた。<B> Since the ends of the umbrella-shaped members of the electrodes and the grooves are brought close enough to be processed, there is no problem with the flow of the lines of magnetic force between each electrode, and the total number of lines of magnetic force does not decrease. , the magnetic force of the armature poles is strengthened. Therefore, there is no need to increase the strength of the current passed through the conductor or the number of windings on the armature, and it is possible to create a motor with higher torque than conventional motors without using expensive high quality magnets. It has been experimentally confirmed that this can be achieved.
