![]() ![]() The results are presented and compared for finding differences between various modeling methods. Both analytical and finite element methods are presented and used for analyzing the designed high speed rotor. Structures of modular actuator designs for AMBs and electric machine are presented and the benefits of having a modular structure are discussed. The need of reconfigurable modular design comes from the possibility of changing the system configuration, in order to test and perform the identification of different AMBs, motor and rotor designs. The thesis scope was chosen to provide a concept design of a reconfigurable test rig, the design and modelling of a rotor of a high-speed induction motor and a documentation of the design process, with the main focus being on the rotor design. In addition, a literature review of test rigs, used in various applications, such as component identification and rotor dynamics studies, is presented. The structure and functionality of AMBs used in this study are introduced. Due to the nature of high speed machinery, introduction to rotordynamics and analyzing methods is presented. Also a number of analytical methods for analyzing mechanical stresses of high speed rotor is presented. First the theory of high speed rotor design is presented. In this master s thesis, the mechanical design and analysis of a modular active magnetic bearing (AMB) test rig is investigated. (Tech.)
