1、Reception check收到电机后立即检查是否有损坏，如发现请立即拨打：0086-21-6463-1777，或发传真至0086-21-6463-7180，检查铭牌数据特别是额定电压、接线方式（星形或三角形）是否与合同订货要求相符，用手转动电机轴检查轴转动是否灵活。Immediately check the motor for external damage upon receipt and if found, please inform us by telephone or fax without delay （Tel:0086-21-6463-1777, Fax:0086-21-646

2、3-7180）. Check all rating plate data, especially voltage and winding connection （star or delta）. Turn shaft by hand to check for free rotation.绝缘电阻检查Insulation resistance check在电机调试前或怀疑线圈受潮时要测量电机的绝缘电阻，在25时的绝缘电阻值应超过以下表达式的值，表达式中：Measure the motors insulation resistance before commissioning or when win

3、ding dampness is suspected. insulation Resistance, measured at 25C, shall exceed the following reference value, i.e. where：R：单位兆欧（用500V绝缘电阻表测量）U表示电压，单位VP表示功率，单位kWR: M（ measured with 500 V dc Megger ）U = voltage, Volts; P = output power, kW.警告：测量完绝缘电阻后应立即将测量线从电机上断开，以免线圈再次受到高电压冲击。环境温度每升高20，绝缘电阻将降低一半，如

4、果绝缘电阻值达不到计算值，表明线圈已经受潮需进行烘干处理。先在90温度下烘12-16小时再在105下烘6-8小时。WARNINGWindings should be discharged immediately after measurement to avoid risk for electric shock. Insulation resistance reference value is halved for each 20C rise in ambient temperature. If the reference resistance value is not attained, t

5、he winding is too damp and must be oven dried. Oven temperature should be 90C for 12-16 hours followed by 105C for 6-8 hours.电机启动Motor starting 单速电机启动（直接或Y/启动）标准单速三相异步电动机的出线盒有6个接线头和至少1个接地接头，接地须根据操作规程在电机接上电源前进行，接线方式和电压应根据接线指示牌及铭牌指示。Start of single speed motor （Direct-on-line or star/delta starting）Th

6、e terminal box on standard single speed motors normally contains 6 winding terminals and at least one earth terminal. Earthing shall be carried out according to local regulations before the machine is connected to the power supply . The voltage and connection are stamped on the nameplate.出线与旋转方向电机的旋

7、转方向：当相序为L1、L2、L3时，在电机拖动端面对轴伸视为顺时针旋转。如要改变转向，只需改变任意两根电源电缆的相序，如果单向旋转的电机，需检查电机转向是否与指示牌上的方向一致。（接线应严格按照接线盒中示意图）Terminals and direction of rotationDirection of rotation is clockwise when viewing the shaft face at the motor drive end, when the line phase sequence L1, L2, L3 is connected to the terminals as

8、shown in the figure. To alter the direction of rotation, interchange the connection of any two-line cables. For the unidirectional motor, checkthat the direction of rotation is according to the arrow marked on the direction board.（The terminals shall be connected in strict accordance with the termin

9、al box drawing.）多速电机启动多速电机一般应低速档启动后切换到高速，对多套绕组的变速电机在不同转速档切换时，应在一绕组断电后才能向另一绕组送电。Start-up of multi-speed motorThe multispeed motor should start at low-speed then shifted to high-speed. For multispeed motors that with many separate windings the speed shift shall be fulfilled when one winding has to be

The cooling blower must be connected to the power frequency supply, and the rotating direction shall be as specified in the nameplate of blower. Adjust t

12、he value of v/f, the motor can obtain different start performance, but if over compensate of voltage will cause overload.使用运行条件电机是用来驱动其他机械，通常环境温度为-25C 到 +40C，海拔高度为1000米以下。（当环境温度与海拔高度不符合上述规定时，铭牌上会注明）UseOperating conditionsThe motors are intended for use in industrial drive applications. Normal ambien
