稀土永磁传动机构的转矩计算及特性分析

Torque Calculation and Feature Analyses of Rare earth Magnet Transmissions

根据电磁场理论，把稀土永磁齿轮传动的磁场作用分为等效电流间作用、等效电流与介质磁化场间作用和两个介质磁化场间的作用３ 部分。在利用积分方程法导出的磁场性能计算公式的基础上，导出了永磁齿轮传动中转矩的计算公式，并对转矩特性进行了分析。

In this paper, based on the electromagnatic field theory, the magnetic action of the rare earth magnet gear transmission is divided into three parts, i.e. the actions between the two equivalent currents, between the equivalent current and magnetized field of the medium, between the two magnetized fields of the media. With help of the formulas of magnet field characteristics which are derived using the integral equation method, the torque formula of the magnet gear transmission is derived, and the torque features are analyzed.
