摘要：
A 2-D analytical model is proposed to calculate the magnetic field distribution in axial magnetic coupler with disk magnets. The 2-D simplification is possible by assuming an infinite radius of the ferromagnetic yokes. Then, an analytical solution is obtained for a single magnet. This solution allows the determination of the magnetic field due to all the magnets so the total magnetic field is obtained by superposition. To demonstrate the validity of the model, the analytical results are compared with those obtained from 3-D finite-element (FE) simulations and from experimental tests carried out on a magnetic coupler equipped with disk magnets and high temperature superconducting (HTS) pancake coils.
