Novel induction plate configuration for permanent magnet electrodynamic wheel systems based on electromagnetic force optimization and its implementation on HTS system

Abstract Permanent magnet electrodynamic wheel (PMEDW) has a broad application prospect because of its unique advantage of integrating levitation and propulsion functions. Considering the cost of the mentioned materials, a low-cost stacked plate design for the induction plate in the PMEDW system is proposed and tested, to improve the electromagnetic force in this paper. The feasibility of the proposed structure is verified through theoretical analysis, finite element simulation analysis, and experimental testing. Firstly, the basic structure and principle of the proposed stacked plate are analyzed. Then, a preliminary simulation analysis is carried out to calculate the electromagnetic force, power loss, and efficiency. The stacked structure has high static levitation efficiency and driving efficiency and has low power loss. Subsequently, experimental tests were conducted and the results showed that the levitation and propulsion forces were effectively increased by 12.99% and 4.8%, respectively. Finally, the stacked plate is verified to have good propulsion capability by a high-speed test bed. This work can significantly enhance the levitation-propulsion features of the PMEDW system. In addition, because the PMEDW has the propulsion ability to replace linear motors, it can be combined with the HTS Maglev train, which greatly reduces the cost and energy consumption.
