近年来，超高速机器越来越引起研究人员的兴趣。开关磁阻电机（srm）由于其简单的转子几何形状而特别令人感兴趣。对于超高速机械，转子动力学是一个重要的组成部分，必须在设计阶段加以考虑。本文对额定转速为100万转/分的超高速SRM转子动力学进行了研究。首先，采用解析和数值方法研究了各向同性和正交异性材料制成的不同转子。然后，研究了叠层与固体叠层的影响。最后，提出了单轴、串轴和双轴三种不同的转子轴几何形状，并对其成本、转矩密度、制造复杂性和转子动态稳定性进行了分析和比较。
Ultra-high speed machines have drawn more and more interest for researchers in recent times. Switched reluctance machines (SRMs) are of particular interest due to their simple rotor geometry. For ultra-high speed machines, rotor dynamics are a major component and must be considered in the design stage. In this paper, a rotor dynamic study of an ultra-high speed SRM with a rated speed of 1 million rpm is presented. First, different rotors built with isotropic and orthotropic materials are studied, using both analytical and numerical methods. Then, the impact of using a laminated stack versus a solid stack is studied. Finally, three different geometries of single, tandem, and bilateral rotor shafts are proposed, analyzed and compared based on their cost, torque density, manufacturing complexity, and rotor dynamic stability.
