Study of an Axial-Flux Modulated Superconducting Magnetic Gear
IEEE Transactions on Applied Superconductivity, 2018An axial-flux modulated superconducting magnetic gear (AFMSMG) is specifically studied using superconducting bulk magnets (SBM) instead of permanent magnets. A mathematical modelling of the SBM as the magnetic field source is built from the point of the physical superconducting mechanism.

A HTS Stator-Excited Axial-Flux Magnetic Gear With Static Seal
IEEE Transactions on Applied Superconductivity, 2021This paper proposes a novel high-temperature superconducting stator-excited axial-flux magnetic gear (HTS-SEAFMG) for the high-torque transmitting system. The proposed magnetic gear combines the merits of both HTS-excitation and stator-excitation. By using the HTS-excitation, a high air-gap flux density can be easily obtained, thus achieving the high ...

Analytical Investigation of the Magnetic-Field Distribution in an Axial-Flux Magnetic-Geared Machine
2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019This paper proposes a novel two-dimensional (2-D) analytical method to predict the performance of an axial-flux magnetic-geared machine under no-load and load condition. The computation is based on the solution of Laplace's or Poisson's equation with boundary conditions for each elementary rectangular region.
