Description
(54) МНОГОПОЛЮСНЫЙ МАГНИТ(54) MULTIPOLUS MAGNET
Изобретение относитс к магнитным системам на посто нных магнитах, используемым в электротехнике и электронике.This invention relates to permanent magnet magnetic systems used in electrical engineering and electronics.
Известны многополюсные магниты, в которых дл формировани магнитных полей особой формы используютс полюсные наконечники специального профил I. Однако наличие почти примыкающих друг к другу наконечников разной пол рности приводит к резкому увеличению рассе ни системы, снижению ее пол и возрастанию массы.Multipole magnets are known in which pole lugs of special profile I are used to form special-field magnetic fields. However, the presence of almost adjacent lugs of different polarity leads to a sharp increase in the dispersion of the system, a decrease in its field and an increase in mass.
Известен также многополюсный магнит, выполненный из материала с посто нной намагниченностью в виде полого цилиндра, собранного из секторов с различным направлением намагниченности и фиксированным ее направлением 2. Такой магнит достаточно компактен, но конфигураци его пол неудовлетворительна.Also known is a multi-pole magnet made of a material with a constant magnetization in the form of a hollow cylinder, assembled from sectors with different directions of magnetization and fixed in its direction 2. Such a magnet is quite compact, but its configuration is unsatisfactory.
Целью изобретени вл етс уменьшение массы магнита. Это достигаетс тем, что в предлагаемом магните угол между направлением намагниченности каждого из секторов и осью сектора выбран из услови The aim of the invention is to reduce the mass of the magnet. This is achieved by the fact that in the proposed magnet the angle between the direction of magnetization of each sector and the sector axis is chosen from the condition
гг ± р .yy ± r.
где р - число пар полюсов;where p is the number of pairs of poles;
а - угол между той же осью и осью симметрии сечени магнита, проход щей через .пару его полюсов.a is the angle between the same axis and the axis of symmetry of the section of the magnet passing through its pair of poles.
На фиг. 1 показан описываемый магнит - источник пол квадрупол ; на фиг. 2 - квадрупольна линза.FIG. 1 shows the described magnet - the source of the field quadrupoles; in fig. 2 - quadrupole lens.
Магнит выполнен из секторов с центральными углами 15 (стрелками показано направление их намагниченности). Такой магнит позвол ет повысить качество магнитных систем дл получени полей мультипольного типа.The magnet is made of sectors with central angles of 15 (the arrows indicate the direction of their magnetization). Such a magnet makes it possible to improve the quality of magnetic systems for obtaining fields of a multipole type.
