...Daoyu Hu; Jianwen Zhang; Feng Gu; Zhuyong Li Purpose The purpose of this study is to propose a modeling method of the equivalent circuit for a new type of high-temperature superconducting partial-core transformer (HTS-PCT) made of ReBCO-coated conductors. Design/methodology/approach...

.... To investigate the results, PMIM simulation is performed according to obtained dynamic equations. Simulation results verify the analytic calculations. Findings In this paper, dynamic equations of PMIM are obtained. These equations are used to determine dynamic equivalent circuits of PMIM. Steady-state...

...Toshihito Shimotani; Yuki Sato; Hajime Igarashi Purpose The purpose of this paper is to propose a fast synthesis method of the equivalent circuits of electromagnetic devices using model order reduction. Finite element method (FEM) has been widely used to design electromagnetic devices. For FE...

... in Figure 3 , where all parameters are referred to the stator. The Γ‐type equivalent circuits are used, with all leakage inductances considered on the rotor side. The stator resistances are omitted in the circuits of Figure 3 . Such stator resistance as well as all 3D parameters are not included in the FE...
