新型12/14无轴承开关磁阻电机的设计
|
摘要
为了解决传统无轴承开关磁阻电机(SRM)悬浮力和转矩之间的耦合,提出一种新型12/14结构的无轴承SRM。新型12/14结构无轴承SRM的特征是定子磁极的内径圆弧为非等间距。特殊的定子结构不仅使无轴承SRM悬浮力和转矩的解耦控制成为可能,也实现了转矩极的短磁路。针对所提出的新型12/14结构无轴承SRM,详细地介绍了悬浮极和转矩极的设计;并利用有限元分析了新型12/14结构无轴承SRM的电磁特性。最后,为了验证所提出结构的正确性,加工了一台样机,并进行相关的测试试验。
In order to solve the magnetic coupling between torque and radial force in the conventional bearingless switched reluctance motor,a novel 12 /14 bearingless switched reluctance motor with single windings was proposed.The feature of the new motor was that it was equipped with non-equidistant inner pole arc stator. The special structure stator not only mades the decoupling control of the radial force and torque in bearingless switched reluctance motor become possible,but also introduced the short path concept to the torque. For the new motor,the design of the torque pole and radial force pole were described in detail. Finite element analysis( FEA) was employed to analyze the electromagnetic characteristics of the new motor. Finally,to verify the validity of proposed structure,one prototype motor was manufactured,and related tests were done.
