Abstract
Электрическая машина, содержащая явнополюсные статор и ротор, установленный снаружи статора и образованный силовым кольцом и магнитной системой. Магнитная система ротора включает пакеты секторных пластин с выемками, в которых размещены пакеты полюсных пластин, имеющих по существу форму треугольника, одна из вершин которого обращена к силовому кольцу, и тангенциально намагниченные магнитные блоки, расположенные между пакетами секторных и полюсных пластин, причем каждый пакет полюсных пластин стянут в аксиальном направлении посредством крепежного элемента, пропущенного через внутреннее отверстие в полюсных пластинах. Электрическая машина отличается тем, что каждая полюсная пластина снабжена прорезью, проходящей от указанного внутреннего отверстия до указанной вершины, и предусмотрен профильный элемент, установленный в области указанной вершины в аксиальном направлении ротора, жестко соединенный через указанную прорезь с крепежным элементом посредством по меньшей мере одной силовой стяжки, таким образом, что указанный профильный элемент прилегает к внутренним торцевым сторонам магнитных блоков.An electric machine containing a salient pole stator and a rotor mounted outside the stator and formed by a power ring and a magnetic system. The rotor magnetic system includes packs of sector plates with recesses, in which packs of pole plates are placed, having essentially the shape of a triangle, one of the vertices of which is facing the power ring, and tangentially magnetized magnetic blocks located between the packs of sector and pole plates, each pack of pole plates plates are pulled together in the axial direction by means of a fastener passed through an internal hole in the pole plates. The electric machine is characterized in that each pole plate is provided with a slot extending from the specified inner hole to the specified top, and a profile element is provided, installed in the area of the specified top in the axial direction of the rotor, rigidly connected through the specified slot to the fastening element by means of at least one power couplers, so that the specified profile element is adjacent to the inner end sides of the magnetic blocks.
