摘　　要：介绍了用于中小型电机转子动平衡的两工位全自动动平衡机的系统组成、工作过程及体系结构,提出了数字跟踪窄带滤波方法,其中心频率可根据转子的转速自适应调整,准确地跟踪不平衡信号的频率,并保证零相移,可有效地去除变频率结构噪声.全面考虑了去重质量分布及圆周槽对实际去除不平衡量的影响,建立了精确的R型铣削去重模型和智能规划系统.开发了基于PCI总线的两级测控系统,将系统的协调控制分为动作级和系统级协调.应用结果表明,上述方法极大地提高了全自动动平衡机的精度和可靠性.System composition, working process and architecture of two-station fully automated balancing machines developed by our lab for medium and small-sized motor products were introduced. According to the characteristics of tested signals of balancing machines, a digital tracking filter method was put for- ward. Its centre frequency can be adaptively tuned consistently with the rotational speed of the work-piece to realize the ability of tracking unbalance signal, so that interference in tested signals can be removed effectively. Considering the effect of armature circumferential, radial, and axial distribution of removed metal and circumferentially distributed slots against magnitude and phase of real unbalance, a higher precision contour milling correction model was built, and intelligent programming system was developed. Moreover, PCI bus-based two-stage measurement and control system was developed. System control was divided into system level and action level. The results of test and application showed that these technologies improve largely the precision and reliability of the automated balancing machine.
