本文分析了采用电容提供谐振工作的高速空芯感应电机的性能。谐振可以使用与机器电感适当调谐的定子和转子电容器获得，尽管可以考虑替代转子电容器。目的是为空心谐振感应电机建立一个简单的分析模型，并利用这个模型来了解其工作原理、局限性和问题。该分析基于经典的IM等效电路，外加定子和转子电容，并考虑不同的控制场景，推导出谐振条件、电容值、峰值转矩和效率以及相关转差值的关键表达式。本文的目的是提供一个全面的了解空心谐振IMs，以评估这些机器的实用性。
The performance of a high-speed air-cored induction machine (IMs) using capacitors to provide resonant operation is analyzed in this paper. Resonance can be obtained using the stator and rotor capacitors appropriately tuned with the machine inductances, though alternative options may be considered instead of rotor capacitors. The aim is to develop a simple analytical model for air-cored resonant induction machines and to use this to obtain an understanding of the operating principles and the limitations and issues. The analysis is based on the classical IM equivalent circuit supplemented with stator and rotor capacitors and considers different control scenarios to derive key expressions for resonance conditions, capacitor values, peak torque and efficiency and related slip values. The aim of this paper is to provide a full understanding of air-cored resonant IMs to assess the practicality of these machines.
