摘要
直流并励电动机运行时转速可能会发生波动,采用数值计算法计算其运行性能十分必要。文章描述了直流并励电动机运行方程,结合有限元方法,运用实例分析其转速波动现象,并提出消除转速波动的一些措施。
The speed fluctuation frequently happened while DC shunt motors operating.It was necessary to calculate the operational performance of DC shunt motors by means of numerical calculation method.The operating equation was presented and described.Some fluctuation phenomenon in the example was analyzed combined with finite element method while some means were suggested to eliminate the fluctuation.
