Original Abstract

Development of high-speed electrical machines reopened a door for further development in a field of magnetic bearing. Conventional ball bearings reached their limits and can’t bear such as high-speed in many modern turbo applications. Another way is to use air bearing which perform lower load capacity and stiffness. Hence, magnetic bearing seemed to be an advantageous solution in many application. The main cons of active magnetic bearing (AMB) are its space requirement and in case of active bearing also power amplifier and controller. In this paper the design of radial AMB for a motor 12 kW, 45000 rpm is calculated. Typically, analytical solution excludes side phenomenons and thus analytically modelled radial AMB is optimized numerically. This paper provides a full design of AMB including design geometry and performance properties.
