“…An effective method to increase the levitation efficiency is hybrid systems in which the PMs are used on the onboard side together with the HTSs. [34][35][36] This method utilises the bigger repulsive force interaction between the PMG and auxiliary onboard PMs. On the other hand, the PMG installation cost is a large part of the installation budget of the system as it is laid along kilometres of rails.…”

“…Therefore, multi-surface HTS-PMG interactions have been offered in previous studies as a good way to enhance the levitation and guidance performance without increasing the PMG construction cost. 36,37 In all levitation systems, the weight of the system is an important parameter since it affects the energy efficiency of the Maglev vehicles or the delivered power density of the motors and generators. Therefore, the total HTS number in the system and total weight have to be decreased without decreasing the force performance.…”

“…But there are commonly used two types of PMGs, conventional 32 and Halbach types, 33 and there is little left to do anymore to optimise them except for increasing the number of permanent magnets (PM). An effective method to increase the levitation efficiency is hybrid systems in which the PMs are used on the onboard side together with the HTSs 34–36 . This method utilises the bigger repulsive force interaction between the PMG and auxiliary onboard PMs.…”

We aimed to enhance the magnetic force efficiency of Maglev systems without increasing total weight. For this aim, we divided YBCO bulks into three slices horizontally to utilize the YBCO‐permanent magnetic guideway (PMG) interaction surface as much as possible. We used whole YBCO above PMGs with different magnetic pole directions (PMG‐A and PMG‐B) in two lying positions of transversal and longitudinal and investigated levitation and guidance force performances. It is determined that levitation and guidance forces by using YBCO in transversal lying mode are bigger compared to the longitudinal mode. For sliced YBCO, the maximum levitation force increased by 69% and 78%, while the guidance force enhancements are determined as 212% and 91%, compared to the whole YBCO above PMG‐A and PMG‐B, respectively. The levitation and guidance force density with respect to the total mass of unit a set of slices YBCO increased by 92% and 106%, respectively, compared to the whole YBCO above PMG‐B in transversal mode. Since the higher levitation force and the lower total weight of the onboard unit are important parameters in point of the energy efficiency in Maglev and other levitation applications, the result of this study supplies useful data for the engineers and industrial partners.
