Aim: The aim of the study is a comparative representation of a hybrid EM suspension (HEMS) for maglev transport and a pure EM configuration. Methods: Several designs have been numerically investigated and compared to conventional EMS. The numerical model has been validated with magnetic measurements on the experimental set-up. Results: The HEMS implies a combination of electromagnets (EM) and permanent magnets (PM) in a common magnetic circuit. The magnets synergy of HEMS has been demonstrated that leads to sufficient reduction in energy consumption and weight as compared to a conventional EMS. Conclusions: A desired performance of HEMS has been achieved. Efficiency of the design solutions has been verified numerically and experimentally.

Aim: The study was focused on measurement of the lifting force of a hybrid EMS (HEMS) prototype. The measured data were used to verify numerical models. Materials and Methods: Measurements were performed on a certified test bench at a large air gap (13 mm, 17 mm). The measured data were compared with results of numerical experiments. Results: A comparison of measured and simulated parameters have proved reliability of numerical models. Conclusions: A prototype of HEMS for maglev transport has been built and bench tested at JSC NIIEFA. The results obtained will be used to establish measurement, prototyping, and inspection procedures for series production.
