| 摘 要： | 根据电磁调速电动机驱动的水泵机组起动过程中的力矩平衡方程，得到水泵转速的变化率与水泵转速和励磁电流的函数关系式，据此进行数值模拟。当给定一个起动过程中水泵转速随起动时间的变化规律，就可得出对应的该水泵机组起动过程中的电磁调速电动机励磁电流控制的规律，并在一个实际的计算机监督控制系统中进行了验证，其转速的变化基本符合数值模拟时设定的转速变化规律。研究方法对其它异步电动机拖动的调速设备的控制软件开发提

| Abstract: | In this paper, by numerical simulation, studied is the determination of eddy-current for the purpose of exciting magnetism of eddy-current coupling drive in the starting process of pump. The results can be applied reliably in the software of the systems controlled by computer. Based on the study, the characteristic of the starting of pump is optimized and promoted. |
