維修伺服電機(jī)的相關(guān)注意事項(xiàng)：一、有的伺服電機(jī)有內(nèi)置的再生制動(dòng)單元，但當(dāng)再生制動(dòng)較頻繁時(shí)可能引起直流母線電壓過(guò)高，這時(shí)需另配再生制動(dòng)電阻，廈門(mén)伺服驅(qū)動(dòng)器故障維修。再生制動(dòng)電阻是否需要另配，配多大的再生制動(dòng)電阻可參照相應(yīng)樣本的使用說(shuō)明。需要注意的是通常樣本列表上的制動(dòng)次數(shù)是電機(jī)在空載時(shí)的數(shù)據(jù)。實(shí)際選型中要先根據(jù)系統(tǒng)的負(fù)載慣量和樣本上的電機(jī)慣量，算出慣量比。再以樣本列表上的制動(dòng)次數(shù)除以（慣量比+1）。這樣得到的數(shù)據(jù)才是允許的制動(dòng)次數(shù)。二、有些系統(tǒng)如傳送裝置，廈門(mén)伺服驅(qū)動(dòng)器故障維修，升降裝置等要求伺服電機(jī)能盡快停車(chē)。而在故障，急停，電源斷電時(shí)伺服器沒(méi)有再生制動(dòng)無(wú)法對(duì)電機(jī)減速。同時(shí)系統(tǒng)的機(jī)械慣量又較大，這時(shí)對(duì)動(dòng)態(tài)制動(dòng)器的選擇要依據(jù)負(fù)載的輕重，廈門(mén)伺服驅(qū)動(dòng)器故障維修，電機(jī)的工作速度等。三、有些系統(tǒng)要維持機(jī)械裝置的靜止位置需伺服電機(jī)提供較大的輸出轉(zhuǎn)矩且停止的時(shí)間較長(zhǎng)，假如使用伺服的自鎖功能會(huì)造成電機(jī)過(guò)熱或放大器過(guò)載。這種情況就要選擇帶電磁制動(dòng)的電機(jī)。

伺服電機(jī)工作原理--是怎樣的呢?交流伺服電機(jī)的工作原理與兩相異步電機(jī)相似。但是由于它在數(shù)控機(jī)床中作為執(zhí)行元件，將交流電信號(hào)轉(zhuǎn)換為軸上的角位移或角速度，所以要求轉(zhuǎn)子速度的快慢能夠反映控制信號(hào)的相位，無(wú)控制信號(hào)時(shí)它不轉(zhuǎn)動(dòng)。由于定子上的兩個(gè)繞組在空間相差90°電角度，如果在兩相繞組上加以幅值相等、相位差90°電角度的對(duì)稱(chēng)電壓，則在電機(jī)的氣隙中產(chǎn)生圓形的旋轉(zhuǎn)磁場(chǎng)。若兩個(gè)電壓的幅值不等或相位不為90°電角度，則產(chǎn)生的磁場(chǎng)將是一個(gè)橢圓形旋轉(zhuǎn)磁場(chǎng)。加在控制繞組上的信號(hào)不同，產(chǎn)生的磁場(chǎng)橢圓度也不同。伺服電機(jī)內(nèi)部的轉(zhuǎn)子是永磁鐵，驅(qū)動(dòng)器控制的U/V/W三相電形成電磁場(chǎng)，轉(zhuǎn)子在此磁場(chǎng)的作用下轉(zhuǎn)動(dòng)，同時(shí)電機(jī)自帶的編碼器反饋信號(hào)給驅(qū)動(dòng)器，驅(qū)動(dòng)器根據(jù)反饋值與目標(biāo)值進(jìn)行比較，調(diào)整轉(zhuǎn)子轉(zhuǎn)動(dòng)的角度。
