摘要
在传统五自由度磁悬浮电主轴结构的基础上,提出了一种由永磁偏置三自由度混合磁轴承和二自由度磁悬浮异步电机构成的五自由度磁悬浮电主轴结构。设计了五自由度磁悬浮电主轴的试验样机,通过电磁场分析软件Asoft/Maxwell分析了样机的磁场和悬浮力,验证了所设计样机结构和参数的合理性。在MATLAB/Simulink环境下构建了控制系统的仿真模型,进行了相关的仿真研究,为磁悬浮电主轴数字控制系统的建立奠定了基础。
Based on the traditional structure of five freedom degree magnetic bearings electric spindle, the two parts of five freedom degree magnetic bearings electric spindle were introduced, which were three freedom degree permanent magnet bias mixed magnetic bearings and two freedom degree magnetic bearings asynchronous motor. Firstly, the prototype of five freedom degree magnetic bearings electric spindle was designed, and then the magnetic force and levitation force by electromagnetic analysis software Asoft/Maxwell was analyzed, thus verifying the structure and parameter rationality of the prototype. Finally, the simulation model of control system in Matlab/Simulink was construc- ted and some related simulation was did, which lays foundation for establishing the control system of the magnetic bearings electric spindle.
