伺服馬達(dá)維修分為機(jī)械、電氣和磁場(chǎng)三類維修。機(jī)械類維修為軸承，外殼等修復(fù)，這些工作屬于簡(jiǎn)單的維修處理，只要配備簡(jiǎn)單的拆卸工具就可以勝任，不過(guò)拆編碼器時(shí)候要小心，因?yàn)槌鰪S時(shí)候編碼器有個(gè)零位置已經(jīng)調(diào)整好，如果挪動(dòng)的話，沒(méi)有一定的技術(shù)功力是調(diào)不回去的。電氣類維修一般為繞線和處理編碼器，繞線可以根據(jù)匝數(shù)和電流（銅線大?。﹣?lái)進(jìn)行，并不復(fù)雜，處理編碼器比較麻煩，如果沒(méi)有配件，很多進(jìn)口伺服馬達(dá)編碼器的零位置是走通訊的（這是洋鬼子動(dòng)的歪腦筋），換成其他品牌的如果沒(méi)有特殊的處理也是沒(méi)有用的，有一些是旋轉(zhuǎn)變壓器相對(duì)容易些，即使有配件，各種廠家的對(duì)零方式也不盡相同，所以經(jīng)驗(yàn)積累很重要了。磁場(chǎng)維修也不容易，因?yàn)閬G磁是常發(fā)生的事情，沒(méi)有專門(mén)的工具基本上沒(méi)有修復(fù)的可能了?？偠灾欧R達(dá)的維修比驅(qū)動(dòng)器的維修要難，目前掌握這一維修技術(shù)的維修公司寥寥無(wú)幾，所以大家努力鉆研肯定會(huì)有回報(bào)的。上海持承自動(dòng)化設(shè)備有限公司主營(yíng)驅(qū)動(dòng)器，如需選型資料，撥打我司電話！</p><div
