The solution, in accordance with the invention, consisting in at least four electromagnets symmetrically positioned inside the cylindrical casing and the electromagnetic core, is made of a set of sheets with a ring shape with internal pole shoes or the shape of integrated or separated horseshoes, however coil winding of each electromagnet is uniformly positioned on two neighbouring pole shoes of the core with the shape of a ring or on both pole shoes of horseshoes and coiled so as the pole shoes of neighbouring electromagnets has opposite polarisation and characterised by the fact that it includes three electromagnets (2,3,4) symmetrically positioned at the edge inside the cylindrical casing (5) with the core (6) of the known ring shape with pole shoes or integrated or separated horseshoes and coils(7,8,9) wound in a familiar manner. Core pole shoes 6, in the shape of a ring, from the side of horseshoes and the axis Z are equipped with rounded projections IfJ positioned symmetrically to the axis d of a pole shoe. In the frontal surface of one of core pole shoes 6, of each electromagnet 2,3,4 there are positioned recesses H, however, on the opposite side - internal edges of electromagnetic pole shoes 2,3,4 are tangential to arc with a adequately adjusted radius. Moreover, the core 6 of each electromagnet (2,3,4) is equipped with mounting holes 12 and the stabilising inlet 13, electromagnets (2,3,4) in the casing (5). |
