Известен индуктор для реверсивного намагничивания, выполненный прямоуголь- ⁵ным из цельной пластины с высокой удельной проводимостью, имеющей сквозное отверстие по форме намагничиваемого образца, выполненного на боковой грани с _Joбольшей площадью [ 1] .Known reversible magnetizing inductor configured with a high conductivity, having a through hole shaped magnetizable sample ⁵ of a rectangular piece plate nym formed on the side faces with larger area _Jo [1].

Недостатком этого устройства является невозможность намагничивания в нем одновременно многополюсных плоских, . кольцевых и дисковых магнитов в осевом направлении. Получение многополюсного магнита в осевом направлении возможно с помощью этого индуктора только склеиванием отдельных магнитов, намагничен— ₂₀ных в этом индукторе, что приводит к возрастанию трудоемкости и энергоемкости изготовления магнита, а следовательно, к его удорожанию. Кроме того, в данном устройстве возможно намагничивание магнитов толькб прямоугольной формы. Наиболее близким'к изобретению по технической сущности является индуктор для радиального намагничивания секторных и кольцевых магнитов, выполненный из ленты с высокой электропроводностью, образующей два замкнутых контура f2] .The disadvantage of this device is the impossibility of magnetizing in it simultaneously multipolar flat,. ring and disk magnets in the axial direction. Preparation of the multipolar magnet in the axial direction is possible by using this inductor only by gluing the individual magnets ₂₀ magnetized in this GOVERNMENTAL inductor, which leads to increased manufacturing complexity and power consumption of the magnet, and hence to its appreciation. In addition, in this device it is possible to magnetize only square rectangular magnets. Closest to the invention in technical essence is an inductor for radial magnetization of sector and ring magnets, made of tape with high electrical conductivity, forming two closed loops f2].

Индуктор работает следующим образо^. ³⁵ The inductor operates as follows. ³⁵

Плоский магнит вводится в рабочую зону между зигзагообразными пластинами 1 и 2, при пропускании тока по пластинам в рабочем зазоре создается разнополярное магнитное поле в аксиальном направлении, конфигурация каждого полюса которого соответствует форме зигзага. При этом намагничиваемые участки магнита имеют ту же форму в плоскости, перпендикуляр- . ной направлению намагничивания. При сов-*⁵падении наружных вершин одной пластины с внутренними вершинами другой и протекании тока в пластинах встречно ·.> участки полюса промагничиваются более концентрированным полем, при совпадении наружных ^!и внутренних вершин обеих зигзагообразных пластин и при протекании тока в пластинах одного направления создаются кон центрированные’поля для намагничивания зубчатых полюсов.A flat magnet is introduced into the working area between the zigzag plates 1 and 2, while passing current through the plates in the working gap, a bipolar magnetic field is created in the axial direction, the configuration of each pole of which corresponds to the shape of the zigzag. In this case, the magnetized sections of the magnet have the same shape in the plane, perpendicular. direction of magnetization. When sov- * ⁵ vertices fall outside of one plate with another inner vertices and a current flows in the opposite plates +.> Pole portions promagnichivayutsya more concentrated field at the coincidence of ^outer! and internal vertices of both zigzag plates, and when current flows in plates of the same direction, concentrated fields are created for magnetizing the serrated poles.

Зигзагообразные пластины выполняются так, чтобы наружные и внутренние вершины соответствовали торцовым частям намагничийаемого участка полюса, а наклон· ные участки повторяли границу раздела полюсов. Так как одновременно намагничиваются все пары полюсов, то ошибка в направлении полюса исключается, что возможно при склеивании.Zigzag plates are made so that the outer and inner vertices correspond to the end parts of the magnetized portion of the pole, and the inclined sections repeat the boundary between the poles. Since all pairs of poles are magnetized at the same time, an error in the direction of the pole is eliminated, which is possible with bonding.

Claims

(54) INDUCTOR FOR MAGNETIZING CONSTANT MAGNETS 1. -, The invention relates to electrical engineering and is intended for reversible and unidirectional magnetization of flat permanent magnets. A known inductor for reversible magnetization, made rectangular from a single plate with high SPARING conductivity, has a through opening in the shape of a sample magnetized on the side face with a larger area of 1}. The disadvantage of this device is the impossibility of magnetization in it at the same time of multipole planar,. ring and disk magnets in the axial direction. The production of a multi-magnet magnet in the axial direction is possible with the help of this inductor only by gluing individual magnets magnetized in this inductor, which leads to an increase in the labor-intensive and energy-intensive production of the magnet, and consequently to its appreciation. In addition, magnets in this device may be magnetized only rectangular in shape. The closest to the invention to the technical essence is an inductor for radially magnetizing sector and ring magnets, made of a tape with high electrical conductivity, forming two closed G23 circuits. The disadvantage of the known inductor is that it can magnetize the permanent magnets only in the radial direction and only the ring shape (or part of the ring). The purpose of the invention is to provide the possibility of simultaneous multi-pole magnetization of flat ring and disk magnets in the axial direction. . This goal is achieved by the fact that in an inductor containing two plates with high electrical conductivity, each of which forms a closed loop fixed in a dielectric block and leads connected to a power source, the plates are zigzagged. their external and internal vertices have the shape of the ends of the poles of a magnetized magnet, and the inclined portions form the boundary between the poles, while the zigzag-shaped contours formed by the first plates are located relative to each other's edges coaxially with the gap. The outer peaks of one of the zigzag plates can be located opposite the inner peaks of the other, and the leads are connected to the power source in such a way that the currents in the plates are directed oppositely. The outer tops of both plates can coincide, and the outlines are connected to the power source in such a way that the ki in the plates are directed to one side. 1 and 2 the described inductor is shown in two projections; Fig, 3 magnetized magnet. The inductor consists of zigzag plates 1 and 2, repeating external. vertices 3 end surface perpendicular to the direction of magnetization (surface of magnetizable section 4 in Fig. 3), internal vertices 5 end surface perpendicular to the direction of magnetization (surface of magnetizable section 6 in FIG. 3), inclined sections 7 - boundary of the area between the poles N-5 or 5 -N, and insulating gaskets 8 and 9. The contours formed by the zigzag plates 1 and 2 end with terminals 10. The inductor operates as follows / A flat magnet is introduced into the work zone between the zigzag different plates 1 and 2 by passing a current through the plates in the working gap is created Hetero-polar magnetic field in the axial direction of each pole configuration which conforms to the shape of a zigzag. In this case, the magnetizable areas of the magnet have the same shape in a plane perpendicular to the direction of magnetization. When the outer vertices of one plate coincide with the inner vertices of the other and the current flows in the plates oppositely: the pole segment is magnetized by a more concentrated field, the outer and inner vertices of both zigzag plates coincide, and when the current flows in the plates of one direction, concentrated floors are created to magnetize the gear teeth . The zigzag plates are made so that the outer and inner peaks correspond to the end portions of the on-the-magnet portion of the pole, and the sloping portions repeat the boundary of the pole. Since all pairs of poles are simultaneously magnetized, an error in the direction of the pole is eliminated, which is possible when gluing.
