摘　　要：为了解决采用传统方法选择的驱动电机不能为旋臂式动态离心机准确提供所需转矩和功率的问题,研究了确定旋臂式离心机中驱动电机额定功率的方法。在分析了作用于负载的总转矩和负载消耗的总功率基础上,根据离心机的运行曲线,建立了计算离心机最大总负载转矩和最大总负载功率的公式。进而提出了计算驱动电动机额定功率的方法,给出了一个解析算例,其结果表明该方法比传统的方法更加准确与合理。In order to solve the problem that the chosen electromotor based on previous calculations could not accurately provide needed rotational moment and power for dynamic centrifuges with rotational arms,the method to determine rating power of the driving electromotor of a centrifuge with rotational arms was investigated.After the analysis of total rotational moment acted on and the total power consumed by the load,the formulas of the maximum total load rotational moment and the maximum total load power were established according to the operation curve of the centrifuge.A method was presented to calculate the rating power of the driving electromotor.And an analytical computational example was carried out.The results show that the present method is much more accurate than previous ones.
