Description
В существующих магнитоэлектрических измерительных приборах магниту придаетс обычно подковообразна форма, а между его полюсами помещаютс сердечник, играющий роль магнитопровода, и подвижна -рамка.In existing magnetoelectric measuring devices, the magnet is usually given a horseshoe-shaped shape, and between its poles are placed a core, which plays the role of a magnetic circuit, and a movable frame.
В насто щее врем также уже известны приборы, В которых магнит проходит внутри подвижной рамки в противоположность устройству вышеназванного типа.At present, devices are also already known, in which a magnet passes inside a moving frame as opposed to a device of the type mentioned above.
Предлагае.мое изобретение касаетс такого рода приборов и преследует цель уменьшени габарита и веса, а также упрощени их конструкции.The present invention relates to such devices and is intended to reduce the size and weight, as well as to simplify their design.
Согласно изобретению, магнит, имеющий форму цилиндра или шара, помещен внутри подвижной рамки коаксиально с последней и намагничен в направлении , перпендикул рном к осн его вращени . Внешн часть магнитопровода сделана из м гкого магнитного материала. Размеры ее могут быть сокращены до минимума, причем во многих случа х она может быть выполнена в виде кожуха прибора из ферромагнитного материала. Роль внешней части магнитопровода сводитс According to the invention, a magnet having the shape of a cylinder or ball is placed inside the moving frame coaxially with the latter and is magnetized in the direction perpendicular to its base of rotation. The external part of the magnetic circuit is made of soft magnetic material. Its dimensions can be reduced to a minimum, and in many cases it can be made in the form of a device casing made of ferromagnetic material. The role of the outer part of the magnetic circuit is reduced
главным образом к экранированию механизма прибора от внешних электромагнитных воздействий.mainly to the shielding of the mechanism of the device from external electromagnetic effects.
В некоторых случа х можно ограничитьс одним магнитом без наружного .магнитопровода, применив дл первого материал с большой коэрцитивной силой , благодар чему еще более упрощаетс конструкци , а также вес и габариты прибора.In some cases, it is possible to confine one magnet without an external magnetic circuit, using a material with a large coercive force for the first, due to which the design, as well as the weight and dimensions of the device, are simplified.
