FIELD: electronic equipment.SUBSTANCE: invention can be used in couplings of vehicle fans. Opposite steel core comprises slots (12; 13) of a steel core located in axial direction similarly with back sides to each other on body (11) of electromagnetic steel core. Method of making opposite steel core includes direct drawing of body (11) of steel core to form slots of steel core arranged similarly with back sides to each other, or direct extrusion of body (11) of steel core to form slots of steel core arranged similarly to with back sides to each other. Electromagnetic coupling of fan, made using opposite steel core comprises first working gap (841) and second working gap (842) on two sides of body (11) of electromagnetic steel core of device with opposite steel core.EFFECT: technical result consists in design simplification.23 cl, 11 dwg |
