Multicriteria Optimization of the High-Speed Magnetoelectric Generator on Hybrid Magnetic Bearings

High-speed magnetoelectric generators are the class of high-energy generators which are characterized by the high efficiency and reliability and the minimum specific mass in comparison with known 0.28-0.4 kg/kW generators, which defines wide prospects of their use at the space and aviation industry, as well as at the decentralized power engineering. The article discusses the problem of optimization of geometric dimensions of the magnetoelectric generator based on hybrid magnetic bearings. Numerical examples of optimization for highspeed generators in various industries are presented. The research results are confirmed by experimental tests. As a result of experimental studies, the developed generator showed high efficiency, which confirms the obtained analytical conclusions.
