摘　　要：由于轴承与转子之间不存在摩擦力,无轴承异步电动机(bearingless induction motor,BIM)不添加润滑油就能实现高速旋转,且具有工作噪声低和振动低等优点,在电气传动领域极其重要的科研与应用价值。但是BIM中电磁关系十分复杂,必须对其进行解耦控制。首先对BIM的工作原理及其数学模型进行分析,其次综述了BIM在解耦控制策略方面的研究现状,同时提出了相关关键问题优化改进的研究发展方向。Due to no friction between the bearing and the rotor,the bearingless induction motor is not required to add the lubricating oil in high speed operation,and it also has the characteristics of low noise and low vibration. So bearingless induction motor is very important in the field of electrical transmission. While there is a very complex electromagnetic relationship in the bearingless induction motor,so the decoupling control must be carried out. In this paper,the working principle and the mathematical model of the bearingless induction motor were described,and the research results of the decoupling control strategy for the bearingless induction motor were summarized. The advantages and disadvantages of the decoupling control strategy were also analyzed and compared. Finally,the future research and development direction of decoupling control was put forward.
