style="font-size:14px;">任何電動機的電磁轉(zhuǎn)矩都是電流和磁通相互作用的結(jié)果，電流是不允許超過額定值的，否則將引起電動機的發(fā)熱。因此，如果磁通減小，電磁轉(zhuǎn)矩也必減小，導(dǎo)致帶載能力降低。由公式E=4.44*K*F*N*Φ可以看出，在變頻調(diào)速時，電動機的磁路隨著運行頻率fX是在相當(dāng)大的范圍內(nèi)變化，它極容易使電動機的磁路嚴重飽和，導(dǎo)致勵磁電流的波形嚴重畸變，產(chǎn)生峰值很高的尖峰電流。因此，頻率與電壓要成比例地改變，即改變頻率的同時控制變頻器輸出電壓，使電動機的磁通保持一定，避免弱磁和磁飽和現(xiàn)象的產(chǎn)生。這種控制方式多用于風(fēng)機、泵類節(jié)能型變頻</span><span
