本文主要从工业实际应用的角度出发,提供了一种从径向磁悬浮电主轴的结构设计开始到控制系统的整个系统的完整新颖的设计方法,其中在结构设计中提出了两个对结构起决定意义的参数——X（每极的圆周宽度/（每极的圆周宽度+每槽的圆周宽度））和Y（槽的径向厚度/每个槽的圆周宽度）,并对它们的科学取值进行了深入的探讨,还给出了由机械特性——刚度和阻尼出发迅速设计出PID控制器的计算公式,最后进行了功率损耗分析和发热量校验.本文在上述理论分析的基础上,设计了样机,安装在机床厂磨床上进行实地磨削实验,性能稳定、良好,其精度达到1μm.
This paper provided a new whole design method about the overall system from the structural design of magnetic bearings to control system design, based on practical applications in industry. It proposed two parameters—x (circumference of each pole/( circumference of each pole + circumference of each groove)) and y(radial thickness of each groove/ circumference of each groove), which play a decisive role in the structural design, and it made a thorough research about them. It also gave the formula of PID controller using the stiffness and damping, the final analysis of a power loss and heat checking. This prototype installed in a grinder ran well and its precision can reach 1μm.
