style="font-size:14px;">任何電動機(jī)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(jī)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(jī)的磁路隨著運(yùn)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(jī)的磁路嚴(yán)重飽和，導(dǎo)致勵磁電流的波形嚴(yán)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(jī)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(jī)、泵類節(jié)能型變頻</span><span

style="text-indent:25px">我們堅(jiān)守著“只有客戶好，公司才能發(fā)展得更好”的理念。云南ABB變頻器維修電話</p><p style="text-indent:25px"><span style="font-size:14px;">變頻器的主電路大體上可分為兩類：電壓型是將電壓源的直流變換為交流的變頻器，直流回路的濾波是電容；電流型是將電流源的直流變換為交流的變頻器，其直流回路濾波是電感。電動機(jī)使用工頻電源驅(qū)動時，電壓下降則電流增加；對于變頻器驅(qū)動，如果頻率下降時電壓也下降，那么電流是否增加？頻率下降（低速）時，如果輸出相同的功率,則電流增加，但在轉(zhuǎn)矩一定的條件下,電流幾乎不變。采用變頻器運(yùn)轉(zhuǎn)，隨著電機(jī)的加速相應(yīng)提高頻率和電壓，起動電流被限制在150%額定電流以下(根據(jù)機(jī)種不同，為125%~200%)。<strong>【云南永樂科技有限公司主要銷售維修變頻器、ABB變頻器、英威騰變頻器、東力變頻器、施耐德變頻器、西門子變頻器等等，如有需求，歡迎大家來電咨詢！】</strong></span>云南ABB變頻器維修電話</p></p><br
