... is well implemented with negligible assumptions. Originality/value Effectiveness and accuracy of the proposed approach is assessed on two different sizes slotted PDD machines. Combining the presented analytical method with meta-heuristic methods can be simply used for the optimal design of PDD...

... method and optimizes the dimensions of the magnets for achieving maximum stiffness. Design/methodology/approach For determining the magnetic fields distribution, forces and stiffness of the bearings, a 2D analytical method is used, based on the subdomain method. For the sake of generalization, all...

...Zheng Xu; Jiamin Wu; Lu Li; Yucheng He; Wei He; Dengjie Yu Purpose Eddy currents are inevitable in magnetic resonance imaging (MRI) systems. These currents are mainly induced by gradient fields. This study aims to propose a fast analytical method to calculate eddy currents induced by frequently...

... and an analytical method. The analytical code is developed because several parameters of the system need to be optimized. Findings The performance of the solution presented is comparable with those of the system with superconductive coils. The results of the two methods applied are in good agreement; thus...
