電動機的控制系統(tǒng)由開關(guān)、保險絲、主副接觸器、繼電器、溫度、感應裝置等組成，相對較復雜。故障多種多樣，常需要借助控制原理圖分析排查。平時要注意保持控制箱內(nèi)、外清潔干燥，不能有水、油污，定期（每周）用小風機吹干凈箱內(nèi)各元件及接線柱、排上的灰塵，或用刷子蘸電器清潔劑刷干凈，以免影響接觸器、繼電器的工作或絕緣。設(shè)有烘潮電阻的控制箱，一般不要隨意關(guān)掉加熱開關(guān)。還應保持箱體接地可靠，預防觸電。對采用星形-三角形(Y-△)方法啟動的（轉(zhuǎn)換延時約5秒）電動機，要察看其轉(zhuǎn)換啟動情況是否正常。通常，生產(chǎn)廠家對電動機的啟動周期(即每分鐘啟動次數(shù))有嚴格規(guī)定，會在起動控制箱上有*示標貼，提醒使用者防止電動機因頻繁啟動而損壞，同時，也為防止起動控制箱內(nèi)的一些電器組件(如起動電抗器等)發(fā)熱燒毀。所以，天津大型電機價格，對起停頻繁或電流大的電動機控制系統(tǒng)，應縮短檢查保養(yǎng)周期，天津大型電機價格。定期檢查熱過載繼電器的保護功能(可撥動旁邊的小紅標色制)其設(shè)定動作值不要超過電動機銘牌的額定電流值，天津大型電機價格，確保能起到過載保護的作用。

三相異步電機（Triple-phaseasynchronousmotor）是感應電動機的一種，是靠同時接入380V三相交流電流（相位差120度）供電的一類電動機，由于三相異步電動機的轉(zhuǎn)子與定子旋轉(zhuǎn)磁場以相同的方向、不同的轉(zhuǎn)速成旋轉(zhuǎn)，存在轉(zhuǎn)差率，所以叫三相異步電動機。三相異步電動機轉(zhuǎn)子的轉(zhuǎn)速低于旋轉(zhuǎn)磁場的轉(zhuǎn)速，轉(zhuǎn)子繞組因與磁場間存在著相對運動而產(chǎn)生電動勢和電流，并與磁場相互作用產(chǎn)生電磁轉(zhuǎn)矩，實現(xiàn)能量變換。與單相異步電動機相比，三相異步電動機運行性能好，并可節(jié)省各種材料。按轉(zhuǎn)子結(jié)構(gòu)的不同，三相異步電動機可分為籠式和繞線式兩種?；\式轉(zhuǎn)子的異步電動機結(jié)構(gòu)簡單、運行可靠、重量輕、價格便宜，得到了普遍的應用，其主要缺點是調(diào)速困難。繞線式三相異步電動機的轉(zhuǎn)子和定子一樣也設(shè)置了三相繞組并通過滑環(huán)、電刷與外部變阻器連接。調(diào)節(jié)變阻器電阻可以改善電動機的起動性能和調(diào)節(jié)電動機的轉(zhuǎn)速。聊城電機維修聯(lián)創(chuàng)電機深受行業(yè)客戶的好評，值得信賴。</p><div

監(jiān)視電動機的溫度。運行中的電動機都要發(fā)熱，其溫升不應超過銘牌上的允許限度。電動機的絕大部分故障都會使它的定子電流增大，溫度升高，因此，如果發(fā)現(xiàn)電動機的溫度超過允許值，應立即停機檢查，查明嚴重發(fā)熱的原因，排除故障后才可以運行。檢查電動機的溫升常用如下方法：1)手摸。對中、小容量的電動機，用手背觸摸電動機的外殼，如果沒有發(fā)燙到要縮手的感覺，說明電動機沒有過熱。如果燙得馬上縮手，難以忍受，則說明電動機的溫度已超過了允許值。用手背而不是用手心摸電動機的外殼，是為了防止機殼一旦帶電時，手背比手心容易自然地擺脫帶電的外殼。為了防止觸電，比較好在摸機殼前，先用驗電筆檢測一下機殼是否帶電。2)滴水。在機殼上滴幾滴水，如果看見冒熱氣而無聲音，說明電動機沒有過熱；如果既冒熱氣，又聽到“咝咝”聲，說明電動機已過熱，溫升已超過允許值。
