Abstract

Предложена электрическая машина, имеющая явнополюсный якорь, каждый полюс которого окружен идентичной катушкой или идентичной группой нескольких катушек, и явнополюсный индуктор с четным числом полюсов чередующейся полярности, отличающаяся тем, что отношение числа полюсов якоря к числу полюсов индуктора является дробным, преимущественно в диапазоне от 0,75 до 1,5, а сам индуктор образован совокупностью следующих друг за другом блоков, каждый из которых состоит из пакета пластин магнитопроводящей стали и двух призматических магнитов, примыкающих к нему с двух сторон гранями одинаковой полярности, образующей полярность блока, так что наименьший угол между указанными гранями составляет 30-75°, а биссектриса этого угла направлена в сторону якоря, причем пакеты соседних блоков отделены друг от друга зазорами толщиной не менее толщины магнита, а также пакетами пластин магнитопроводящей стали, имеющих контакт с пакетами блоков только через магниты этих блоков и зазоры толщиной не менее толщины магнита, при этом все последовательные блоки одной полярности образуют полюс индуктора данной полярности, а со стороны, противоположной якорю, пакеты пластин магнитопроводящей стали формируют практически непрерывную поверхность со щелями, толщиной не более 1-2% от толщины магнита.An electric machine with a pole-pole armature, each pole of which is surrounded by an identical coil or an identical group of several coils, and a pole-pole inductor with an even number of poles of alternating polarity, characterized by the fact that the ratio of the number of armature poles to the number of poles of the inductor is fractional, mainly in the range from 0 , 75 to 1.5, and the inductor itself is formed by a set of successive blocks, each of which consists of a package of plates of magnetic conductive steel and two prismatic magnets, with The sides of the same polarity, which form the polarity of the block, are pointing to it from both sides, so that the smallest angle between these faces is 30-75 °, and the bisector of this angle is directed towards the anchor, and the packages of neighboring blocks are separated from each other by gaps of thickness not less than the thickness of the magnet , as well as packages of plates of magnetic conductive steel, which come into contact with the packages of blocks only through the magnets of these blocks and gaps not less than the thickness of the magnet, all successive blocks of the same polarity form an inductive pole This polarity, and from the side opposite to the armature, packages of plates of magnetic conductive plates form an almost continuous surface with slots with a thickness of no more than 1-2% of the magnet thickness.
