Abstract
In this study, considerations of a mechanical design of a reconfigurable active magnetic bearing (AMB) test rigand some of its interchangeable modules are reviewed. The manufacturing of modules, assembly, measurementsof mechanical accuracies and their influence on electrical and control requirements of the active components areanalyzed. Numerical simulations for 10 kW 30000 rpm high-speed rotor of induction motor are performed forstudying purposes of rotor dynamics and mechanical stresses of various changeable rotor sleeve parts. Importantpart of high-speed AMB system are mechanical backup bearings. Additional sub-modules are designed forchangeable backup bearings for further rotor dropdown experiments. Also, reference sensors required by the AMBcontrol system are fitted into own sub-module in order to enable testing of various sensor designs. Experimentalmeasurement are performed in order to study rotor dynamics and mechanical accuracies of modular test rig design.Some operational results during commissioning phase are presented and discussed. The benefits and challengesof using a modular design are discussed. The scope of this paper is in mechanical design, therefore no detaileddescription of designed AMBs and control system is presented.
