獨立磁路混合勵磁電機(jī)有限元分析

針對一種新型的獨立磁路混合勵磁電機(jī)，本文首先論述了該電機(jī)的結(jié)構(gòu)和工作原理。然后，運(yùn)用二維有限元軟件對電機(jī)性能進(jìn)行仿真分析，驗證該電機(jī)的磁場調(diào)節(jié)特性。最后，從電磁性能和機(jī)械性能兩方面，對隔磁結(jié)構(gòu)進(jìn)行了優(yōu)化設(shè)計。樣機(jī)試驗數(shù)據(jù)和有限元仿真計算結(jié)果基本吻合。
Abstract: On the new type hybrid excitation machine with isolated magnetic paths, its structure and operation mechanism are described first in this paper. Then with resort to the 2D Finite-element Software, its performance is simulated to further verify its magnetic field adjustment characteristics. Finally, considering both the electromagnetic and the mechanical characteristics, the magnetic isolating gap is optimized. The tested result of the prototype machine agrees with the simulated one as expected
