6、ding): 80note: the connection way can be different from the above parameters for the special requested motors(such as different frequency and voltage).二、安装前的准备 电动机开箱前应检查包装是否完整无损，有无受潮的迹象。 电动机开箱后应小心清除电机上的灰尘及防锈层。 检查电动机的铭牌数据是否符合使用要求。 仔细检查电动机在运输过程中，有无变形或损坏，紧固件是否松动或脱落，试用手转动电机是否灵活。 用500v兆欧表测量绝缘电阻，其值不应低于5m，

7、否则应对定子绕组进行干燥处理。干燥处理的温度不允许超过120。1(4)it has thermal protected device at normal, and adjusting the related data based on the current at the brand.(5)while the frequency has more 1% with brand data or voltage has more 5%, it is not continued to put out the certain watt.for the continued working motor, i

8、t is not permitted to load.(6)empty or load working motor should not happen to continuous or strange sounds or vibration. the shaft temperature is not allowed to exceed 95. 五、电动机的维护、修理使用环境应经常保持干燥，电动机表面应保持清洁。进风口不应受尘土、纤维等阻碍。当电动机的热保护及短路保护连续发生动作时，应查明故障来自电动机还是超负荷或保护装置整定值太底。消除故障后方可投入运行。应保证电动机在运行过程中良好的润滑。2

9、极电动机运行2000小时，4、6、8极电动机运行4000小时，即应补充或更换润滑脂（密封轴承在使用寿命内不必更换润滑脂），运行中发现轴承过热或润滑脂变质时，应及时更换润滑脂，更换润滑脂时应清除旧的润滑脂，并用洗涤剂洗净轴承及轴承盖的油槽，然后将zl3锂基润滑脂填充轴承内外圈之间空腔的1/2（对2极）或2/3（对4、6、8极）。 当轴承寿命终了时，电动机运行时的振动及噪声将明显增大、检查轴承的径向游隙达到下列数值时，即应更换轴承。轴承内腔（mm）20-3035-5055-8080-120极限磨损游隙（mm）0.100.150.200.30 拆卸电动机时，从轴伸端或非轴伸端取出转子都可以。如果没有

10、必要卸下风扇，还是从非轴伸端取出转子较为便利，从定子中抽出转子时，应防止损坏定子绕组或绝缘。5.maintains and repair42.preparation(1)to check if the package is damaged or damped before opening the box.(2)to clean the dust and anti-rust layer.(3)to check if the data on the nameplate as requests.(4)to check if the motor unshaped or damaged and if t
