摘　　要：从直流电动机力矩平衡方程式出发 ,导出了用自由停车法测试电动机传动系统时间常数TM 值的三种形式的计算公式 ,讨论了它们之间的关系和优缺点 ,较全面地考虑了测试和计算误差 ,对于精确测定可控硅直流调整系统中电动机的TMWT5”BZ]Starting from the direct current motors equation of momental equilibrium,the formulae of three kinds for using“free stopping”to test the time constant T M are derived.Their relationships as well as good and bad are alse discussed here.The tests and errors are considered comprchrensively,Which have a practical signficance for testing the motors T M of the silicar controlled direct current governing system accurately.
