摘要

近年来，无刷双馈感应电机(BDFIM)由于提供频率控制而在风能领域变得越来越重要。特别是，没有电刷使该机器在海上风能应用中具有重要意义。由于BDFIM有两个定子绕组和特殊的转子结构，因此其磁场分析与其他机器不同，分析起来比较复杂。由于BDFIM的特殊结构，其谐波过多。本文利用解析法和Matlab对气隙中BDFIM的磁场进行了分析。此外，还研究了定子槽结构对气隙磁场的影响，以及定子槽数、极对数等变量对磁场和THD的影响。

Analysis of stator slot structure effects on magnetic field in brushless doubly fed induction machine

In recent years, Brushless Doubly Fed Induction Machine (BDFIM) becomes more important for wind energy because BDFIM provides frequency control. Especially, absence of brush makes this machine significant for offshore wind energy application. This machine has two stator windings and special rotor construction, so analysis of magnetic field of BDFIM is different from other machines and quite complicated. BDFIM has too many harmonics due to its special structure. In this paper magnetic field of BDFIM in air gap is analyzed with analytical method and Matlab. Additionally, effect of stator slot structure on air gap magnetic field and the effects of stator variables such as slot number and pole pair numbers on magnetic field and THD are investigated.
