Claims (1)

Способ реверсивного намагничивания многополюсных постоянных магнитов и магнитных систем, включающий импульсное намагничивание в электромагнитах, отличающийся тем, что магнит или систему предварительно намагничивают до технического насыщения в аксиальном направлении в двухполюсном электромагните, а затем перемагничивают его в многополюсном электромагните с требуемым числом пар полюсов в аксиальном направлении, при этом, напряженность магнитного поля, создаваемого многополюсным индуктором в зонах, совпадающих с направлением предварительного намагничивания, равна 1,2-1,4 коэрцитивной сила материала магнита, а в зонах с противоположным направлением равна 3-5 коэрцитивной силы материала магнита.A method for reversing magnetization of multi-pole permanent magnets and magnetic systems, including pulsed magnetization in electromagnets, characterized in that the magnet or system is pre-magnetized to technical saturation in the axial direction in a bipolar electromagnet, and then magnetized in a multipolar electromagnet with the required number of pole pairs in the axial at the same time, the magnetic field generated by a multipolar inductor in zones coinciding with the direction of ritelnogo magnetization is equal to 1.2-1.4 of the coercive force of the magnet material, and in areas with the opposite direction is 3-5 in the coercive force of the magnet material.
