WebMar 24, 2024 · What is passive levitation? Current maglev systems used by SCMaglev (Japan), CRRC (China), Transrapid (Germany) are using active levitation which means that the electromagnets both in the train and the track are supplied by energy. In the case of passive levitation, the levitating-effect is achieved by speed. WebAccurate large-displacement magnetic levitation actuation and its stability remain difficult in non-liquid environments. A magnetic levitation actuation and motion control system with active levitation mode is proposed in this paper. The actuating force of the system is generated by the external magnetic field.
