Description
Известны способы шлифовки поверхности многослойного магнитопровода , например, ротора электрических машин.Known methods of grinding the surface of a multilayer magnetic circuit, for example, the rotor of electrical machines.
При существующих способах благодар «замазываюш,ему действию абразива частично нарушаетс изол ци между листами железа и на поверхности ротора по вл етс провод щий слой, значительно увеличивающий потери на вихревые токи.With the existing methods, thanks to the gouging, the action of the abrasive is partially disturbed by the insulation between the iron sheets and a conductive layer appears on the surface of the rotor, which significantly increases eddy current losses.
В описываемом способе обработка ротора производитс по методу электроискрового шлифовани с использованием в качестве электродаинструмента чугунного диска.In the described method, the rotor is machined according to the electric spark grinding method using a cast iron disc as an electric tool.
При этом соверщенно исключаетс возможность нарушени изол ции , а таклсе по влени царапин и «замазывани поверхности ротора.This completely eliminates the possibility of breaking the insulation, as well as the occurrence of scratches and "smearing of the rotor surface."
Предмет изобретени Subject invention
Способ шлифовки поверхности расслоенного магнитопровода, например , ротора электрической машины, имеющего изол цию между листами, отличающийс тем, что, с целью предотвращени нарушени изол ции между листами и тем самым уменьшени noiepb на вихревые токи при работе маш.ины, обработку поверхности производ т по методу электроискрового пмифовани .The method of grinding the surface of a stratified magnetic circuit, for example, a rotor of an electric machine, having an insulation between the sheets, characterized in that, in order to prevent the insulation between the sheets from breaking and thereby reducing noiepb to eddy currents during machine operation, the surface treatment is done according to the method of electrospark pythyphonism.
