摘要
针对永磁电机调磁困难、恒功率调速范围窄等问题,设计了一种新型混合励磁同步电机(HESM)驱动系统。重点阐述混合励磁电机调磁机理、剖析两种磁势源(永磁体和电励磁)的工作原理及协调分配情况,最后提出高效的分区控制策略并通过实验验证了驱动系统的可行性与高效性。
Aiming at the problems of permanent magnet motor magnetic adjustment difficulties, constant power speed range is narrow, a new hybrid excitation synchronous motor（HESM） drive system is designed.Focuses on hybrid exci- tation motor magnetic transfer mechanism, the working principle and coordinate distribution of two kinds of magnetic potential source（permanent magnets and electric excitation） are analyzed.Finally,efficient zoning control strategy is pr- oposed and the feasibility and efficiency of the drive system are verified hv exn^rlrn^nt~
