Research of electromagnetic support for high-speed spindle knots

The electrospindle design on electromagnetic bearings is described. Experimental researches have shown that electromagnetic bearings possess the high high-speed factor, enough high bearing ability and rigidity, don't de-mand the big expenses of energy and split-hair accuracy of processing of details. However questions of their use in шпиндельных knots of machine tools and maintenance of high operational reliability demand further theoretical and experimental researches.
