直流电动机调压调速直流电动机调压调速speed control of DC motor by changing the armature voltagezh一1 lud旧ndongJ一tlooyo tloosu宜流电动机调压调速(speed。ontrol ofDCmotor by ehanging the armature voltage)通过改变直流电动机电枢电压实现直流电动机调速的技术。各种直流电动机都可以通过改变电枢电压来调速(见1流电动机调速)。他励直流电动机调压调速时的机械特性如图1所示.图1中n为电枢电压为额定值UN时的转速，当负载一定时，随，电枢电压的降低(UN>U，>U:>U。)，直流电动机转速也降低(n>n:>，2>，3)。直流电动机调压调速具有负载变化时速度稳定性好、响应快、调速范围宽等优点，当电源电压连续可调时，能实现无级调速。这种方法是调速性能较好的一种直流电动机调速方法。直流电动机调图1他励直流电动机调压调速时的机械特性压调速可采用以下方法:直流电动机电枢串并联调速、电枢串联升压发电机调速、汞弧整流器直流调速、电动发电机组直流调速、电机扩大机直流调速、磁放大器直流调速、晶问管相位控制直流调速和斩波控制直流调速。直流电动机电枢串并联调速某机械由N台等转速的直流电动机拖动，这些直流电动机的规格相同，它们的轴与轴之间又有足够牢固的机械联系，则可将这些直流电动机的电枢加以串联，并串人起动电阻，再接到恒定直流电源电压U上。起动时逐步减少起动电阻阻值，直到完全切除。这样，每台电动机受到的电压为U/N。改变串联的电机数，使之相应转人并联支路，即可实现有级调速。此法特点为线路简单、节能，多用于电力机车调速。直流电动机电枢串联升压发电机调速将直流电动机电枢与直流发电机电枢串联，再接到共用直流电源(见图2)，则电动机电枢的电压等于共用电源电压加(或减)被串接的直流发电机端电压。调节共用电源电压或串联的直流发电机(又称、幢户哩一鱿共用直流电源图2直流电动机电枢串联升压发电机调速典型线路升压发电机)的电压都可调节电动机的电枢电压，实现各电动机的单独调速。升压发电机的额定电压通常比被其控制的拖动电动机小，但额定电流值相近，升压发电机的控制功率也较小，且反应快。在反应更快、换能效率更高且无旋转部分的半导体变流装置问世以前.此调速法多被用于对转速拉制有高动态要求的机械，如分部传动长网造纸机、连续加工机械等。汞弧整流器直流调速用汞弧整流器将交流电整流成直流电，供电给直流电动机，通过相位控制调节直流整流电压，实现直流电动机调速的技术.本调速法具有节约用铜、节省安装羞础的投资等优点，但存在水银污染环境、深调速区段功率因数低等问题。汞弧整流器直流调速的工业应用盛行于20世纪40~50年代，随粉晶用甘相位技制立流调速的发展，因其具有可靠性高、维护更方便、不污染使用环境、功率放大倍数和能t效率均更高等优点，而取代了汞弧整流器直流调速。
