摘要
应用Matlab对并励直流电动机直接起动和串电阻分级起动进行了仿真,得到了两种起动方式下的电枢电流和转速的波形,并对电流波形和转速波形进行对比分析,最终确定了并励直流电动机起动电阻的各级阻值及各级电阻的切换时间,为并励直流电动机起动系统的设计提供了必要的理论依据。
Simulating the direct starting and the series resistance grading starting of shunt DC motor by Matlab,getting the armature current and the rotational speed waveform of these two starting manners, and analysising the current waveform and rotational speed waveform contrastively.Finnaly, ascertaining the numberical values of all levels resistance and the time between all levels resistance when shunt DC motor starts.It provides the necessary theoretical basis for the design of shunt DC motor starting system.
