The use of magnetic bearings in electrical drive systems enable very long lifetimes at highest speeds and the operation in high-purity or vacuum environments. The machine prototype presented in this paper overcomes several limitations of previously presented high-speed magnetically-levitated electrical drive systems. Linear bearing characteristics result from the slotless design, which enables applying linear state feedback control without linearization of bearing actuators. A multivariable… CONTINUE READING
