  • An electric machine supported by an active magnetic bearing (AMB) can realize ultrahigh speed and high power density, and it is developing toward the trends of higher rotation speed and higher power density. The displacement sensor used for an AMB is one of the most important components in a magnetic suspension electric machine, so improving the dynamic response and the resolution of the displacement sensor become a critical technology. In this paper, a novel self-differential eddy-current… CONTINUE READING
