上海歐臬SWAN鈉探測(cè)器A-87.932.020廠家直銷下面介紹速度-動(dòng)態(tài)轉(zhuǎn)矩（dynamictorque）特性的測(cè)量法。步進(jìn)電機(jī)的動(dòng)態(tài)轉(zhuǎn)矩有失步轉(zhuǎn)矩與起動(dòng)轉(zhuǎn)矩。這兩種轉(zhuǎn)矩隨驅(qū)動(dòng)頻率的增加而下降，原因是由于線圈的電抗增加，電流減少造成的。在低速運(yùn)行時(shí)，其運(yùn)行在振動(dòng)帶區(qū)域，轉(zhuǎn)矩會(huì)突然下降，此為轉(zhuǎn)子的自然振動(dòng)頻率與驅(qū)動(dòng)頻率共振產(chǎn)生的現(xiàn)象；或者，在轉(zhuǎn)子轉(zhuǎn)動(dòng)方向突然發(fā)生改變瞬間，同時(shí)接收到驅(qū)動(dòng)指令脈沖，也會(huì)產(chǎn)生此現(xiàn)象。這些現(xiàn)象均需要正確測(cè)量電磁轉(zhuǎn)矩。本節(jié)介紹3種測(cè)量轉(zhuǎn)矩的方法及其測(cè)量原理。
