1、JR、JS系列的電機是中型三相異步電動機，是我國50年代未60年代初統(tǒng)一設計的中型電動機，它分低壓和高壓兩部分， 都是中型三相電動機的基本系列。型系列三相電動機，是我國近年來研制成功的節(jié)能新型電機。JR、JS系列的電機基本淘汰被Y系列所取代。 功率相同即是容量相同，只是 丫型系列電機體積比JR、JS系列電機體積小本文摘自：JR系列電動機JR系列電動機為驅動各種不同機械之用，如通風機、壓縮機、水泵、破碎機、切削機床、榆樹機械及其他設備等。本系列電動機一般為為自通風防護式。 電動機應在海拔高度不超過1,000米，使用地點空氣溫度不高于+40 C的室內正常 工作，溫升限度符合國家標準 GB/T755

2、-2000的規(guī)定。 本系列電動機符合機械工業(yè)部部頒標準 JB563-64和JB564-64 的規(guī)定。本系列電動機共分為五個機座號，即11、12、13、14及15號機座。例如：（1） JS147-6表示鼠籠轉子型異步電 動機，14號機座，定子鐵心長度為7號，6極。（2） JR147-10表示繞線轉子型異步電動機，14號機座，定子鐵心長度 為7號，10極、JS JR系列概述J系列中型電機可驅動各種不同的機械，如通風機、壓縮機、水泵、破碎機、球磨機、要削機床、運輸機械及其他設備，可供煤礦、機械工業(yè)、發(fā)電廠及各種工礦企業(yè)中作原動機用。JS系列為鼠籠轉子三相異步電機。JR系列為繞線轉子三相異步電機。JS

3、系列電機符合部頒機準JB563-64技術條件的規(guī)定。JR系列電機符合部頒機準JB564-64技術條件的規(guī)定。本系列電機為防護式。根據用戶需要也可制成 管道通風式。防護式電機應裝置在海拔高度不超過1KM，周圍空氣溫度不高于+40C，不低于0C,空氣清潔，無酸、堿等腐蝕性 氣體的室內。電機不允許在含有爆炸性氣體或塵埃較多的環(huán)境中工作。當電機周圍空氣的溫度超過上述規(guī)定或空氣不清潔時，應采用管道通用方式。此時，通入電機兩端的冷卻空氣溫度 應為0C40C并且應保證管道和電機內部的空氣壓力高于周圍空氣的壓力，必要時應加裝鼓風機、濾塵器等。JS系列鼠籠型電機允許全電壓直接起動。最初起動轉矩和最初起動電流數(shù)值

4、分別與額定值之比，如表3所示。如用戶的電網不允許全電壓直接起動時，可以采用降低電壓起動。但此時起動轉矩將與起動電壓成平方關系降低JR系列電機在起動時必須預先在轉子回路內接入起動變阻器 。不允許將轉子繞組直接短接起動。二、結構簡述電機的其本安裝型式機座帶底腳臥式安裝，所有型號的電機都可采用聯(lián)軸器與被驅動機械聯(lián)接。電機采用兩側對稱 的徑向通風系統(tǒng)，冷卻空氣自兩側端蓋的進風口進入，一部分經過電機轉子上的風扇或風葉片吹過定子線圈的端接部分， 另一部分空氣經過轉子鐵心中的徑向通風槽，然后由機座側面的出風口逸出。管道通風式電機的通風系統(tǒng)與上述相同。電機的軸承采用滾動軸承。所用的軸承牌號見表 1,軸承潤滑脂

5、牌號為鋰基潤滑脂ZL-3。表1機座號FrameNO.軸承規(guī)格Bearing NO.軸伸端Drivi ng end非軸伸端Non-driv ing end11NU319631912NU320632013NU32263221422228NU3241522230CNU326從電機的軸伸端看，出線盒在機座的右側JS系列電機可以根據用戶的要求制成雙軸伸，其中任一個軸伸均可用以傳達電機的額定功率（球軸承端只能用于聯(lián)軸器傳動）。JR系列電機在降低轉矩的條件下，允許長期減速運轉。此進，允許輸出的功率和轉矩與轉速的對應關系應符合表2的規(guī)如果電機的負載轉矩（驅動鼓風機、水泵等時）和轉速成平方關系下降時，電機允許在
