JS、JR系列电机技术数据

1、JR、JS系列的电机是中型三相异步电动机，是我国50年代未60年代初统一设计的中型电动机，它分低压和高压两部分，都是中型三相电动机的基本系列。Y型系列三相电动机，是我国近年来研制成功的节能新型电机。JR、JS系列的电机基本淘汰被Y系列所取代。功率相同即是容量相同，只是Y型系列电机体积比JR、JS系列电机体积小本文摘自:JR系列电动机JR系列电动机为驱动各种不同机械之用，如通风机、压缩机、水泵、破碎机、切削机床、榆树机械及其他设备等。 本系列电动机一般为为自通风防护式。 电动机应在海拔高度不超过1,000米，使用地点空气温度不高于+40的室内正常工作，温升限度符合国家标准GB/T755-2000

2、的规定。 本系列电动机符合机械工业部部颁标准JB563-64和JB564-64的规定。 本系列电动机共分为五个机座号，即11、12、13、14及15号机座。 例如： （1）JS147-6表示鼠笼转子型异步电动机，14号机座，定子铁心长度为7号，6极。 （2）JR147-10表示绕线转子型异步电动机，14号机座，定子铁心长度为7号，10极一、JS、JR系列概述J系列中型电机可驱动各种不同的机械，如通风机、压缩机、水泵、破碎机、球磨机、要削机床、运输机械及其他设备，可供煤矿、机械工业、发电厂及各种工矿企业中作原动机用。JS系列为鼠笼转子三相异步电机。JR系列为绕线转子三相异步电机。JS系列电机符合

3、部颁机准JB563-64技术条件的规定。JR系列电机符合部颁机准JB564-64技术条件的规定。本系列电机为防护式。根据用户需要也可制成管道通风式。防护式电机应装置在海拔高度不超过1KM，周围空气温度不高于+40，不低于0，空气清洁，无酸、碱等腐蚀性气体的室内。电机不允许在含有爆炸性气体或尘埃较多的环境中工作。当电机周围空气的温度超过上述规定或空气不清洁时，应采用管道通用方式。此时，通入电机两端的冷却空气温度应为040并且应保证管道和电机内部的空气压力高于周围空气的压力，必要时应加装鼓风机、滤尘器等。JS系列鼠笼型电机允许全电压直接起动。最初起动转矩和最初起动电流数值分别与额定值之比，如表3所

4、示。如用户的电网不允许全电压直接起动时，可以采用降低电压起动。但此时起动转矩将与起动电压成平方关系降低。JR系列电机在起动时必须预先在转子回路内接入起动变阻器。不允许将转子绕组直接短接起动。二、结构简述电机的其本安装型式机座带底脚卧式安装，所有型号的电机都可采用联轴器与被驱动机械联接。电机采用两侧对称的径向通风系统，冷却空气自两侧端盖的进风口进入，一部分经过电机转子上的风扇或风叶片吹过定子线圈的端接部分，另一部分空气经过转子铁心中的径向通风槽，然后由机座侧面的出风口逸出。管道通风式电机的通风系统与上述相同。电机的轴承采用滚动轴承。所用的轴承牌号见表1，轴承润滑脂牌号为锂基润滑脂ZL-3。表1机
