1、什么是電動(dòng)機(jī)的功率因數(shù)？異步電動(dòng)機(jī)的功率因數(shù)是衡量在異步電動(dòng)機(jī)輸入的視在功率（即容量等于三倍相電流與相電壓的重的大小，其值為輸入的有功功率Pl與視在功率S之比，用cos來(lái)表示。電動(dòng)機(jī)在運(yùn)行中，功率因數(shù)是關(guān)，電動(dòng)機(jī)空載運(yùn)行時(shí)，定子繞組的電流基本上是產(chǎn)生旋轉(zhuǎn)磁場(chǎng)的無(wú)功電流分量，有功電流分量很小右，當(dāng)電動(dòng)機(jī)帶上負(fù)載運(yùn)行時(shí)，要輸出機(jī)械功率，定子繞組電流中的有功電流分量增加，功率因數(shù)也時(shí)，功率因數(shù)達(dá)到最大值，一般約為0.7-0.9。因此，電動(dòng)機(jī)應(yīng)避免空載運(yùn)行，防止“大馬拉小車(chē)”現(xiàn)什么是電動(dòng)機(jī)的輸入功率和輸出功率電動(dòng)機(jī)從電源吸取的有功功率，稱(chēng)為電動(dòng)機(jī)的輸入功率，一般用P1表示。而電動(dòng)機(jī)轉(zhuǎn)軸上輸出的示。在額

2、定負(fù)載下，P2就是額定功率Pn。P2=1.732IVcos電動(dòng)機(jī)運(yùn)行時(shí)，內(nèi)部總有一定的功率損耗，這些損耗包括：繞組上的銅（或鋁）損耗，鐵芯上的鐵功率P1等于損耗功率與輸出功率P2之和，也就是說(shuō)，輸出功率小于輸入功率。P1=1.732IVcos什么是電動(dòng)機(jī)的效率電動(dòng)機(jī)內(nèi)部功率損耗的大小是用效率來(lái)衡量的，輸出功率與輸入功率的比值稱(chēng)為電動(dòng)機(jī)的效率，其代效率高，說(shuō)明損耗小，節(jié)約電能。但過(guò)高的效率要求，將使電動(dòng)機(jī)的成本增加。一般異步電動(dòng)機(jī)在額機(jī)的效率也隨著負(fù)載的大小而變化。空載時(shí)效率為零，負(fù)載增加，效率隨之增大，當(dāng)負(fù)載為額定負(fù)載Y系列電動(dòng)機(jī)是一般用途的全封閉自扇冷式鼠籠型三相異步電動(dòng)機(jī)。安裝尺寸和功率等
