提出了一种管状线性磁齿轮，它新利用高温超导体（HTS）块体进行场调制。与传统拓扑相比，所提出的拓扑可以显着减少漏磁通，从而提高其传力能力。利用磁路建模，首先推导了气隙磁通密度和推力的解析公式。然后，采用有限元方法（FEM）来验证所提出的线性磁齿轮的性能。
A tubular linear magnetic gear is proposed, which newly utilizes high temperature superconductor (HTS) bulks for its field modulation. Compared to the conventional one, the proposed topology can significantly reduce the leakage flux, hence improving its force transmission capacity. By using the magnetic circuit modeling, the analytical formulae of air-gap flux density and thrust force are firstly derived. Then, the finite element method (FEM) is employed to validate the performance of the proposed linear magnetic gear.
