armature flux

Due to larger equivalent air-gap and flux leakage of slotless permanent magnet linear synchronous motor ( PMLSM), magnetizing current method was adopted to obtain equivalent current density of permanent magnet, however armature current was considered in practice.

建立无槽式永磁直线同步电动机分层解析模型，由于电机等效气隙较长、漏磁较大，采用磁化电流法等效永磁体电流密度，电枢电流按实际情况考虑。

Results show that the highest place of flux density is superposition of armature and guide sleeve end of pole piece, and the changing for pole piece inside diameter unilateral gap settle on the thrust characteristic.

通过可视化模拟和分析得知，磁通密度最高的地方是衔铁与极靴导套端重叠部分，极靴内径单侧间隙的变化对吸力起决定作用。

This paper has analysed the magnetic field distribution in YCT under noload and the influence of different armature reactions, and especially, the main flux variance with armature reaction. We provide the foundation to unify the design for engineering.

本文分析了YCT电机空载和在不同电枢反应影响下磁场分布情况，尤其是分析了主磁通分布和受电枢反应影响的变化情况，为在工程上统一设计方法奠定了基础。
