三，安装前的准备Third, pre-installation preparation
1.电动机使用前应该检查电动机外表是否完善无损伤，有无受潮的现象。1. THE MOTOR SHOULD BE CHECKED BEFORE USING， THERE HAS TO BE NO DAMAGE ON THE MOTOR OUTSIDE, AND THE MOTOR CAN NOT BE DAMPED.
2.检查电动机的铭牌数据是否符合要求。2. Check the motor nameplate data to meet the requirements.
3.仔细检查电动机在运输过程中有无变形或者损坏，紧固件有无松动或者脱落，试着用手拨动转轴，看电动机是否能灵活运转。电动机的安装3. Carefully check motor during transport without deformation or damage, fasteners loose or fall off, try to toggle the shaft by hand to see if the motor can operate flexibly.
4．电动机应该按照其结构形式正确安装，电动机的轴伸直径出厂前已精磨至标准公差尺寸，因此要求用户所配套的皮带轮或者其他配套零件的内径尺寸一定要按照国家标准推荐的优先配合公差进行磨削或者铰削加工。安装时，用手推入或用榔头轻敲至轴伸台即可，严禁用锤猛击，否则将损坏电动机的零件，造成电动机不能正常工作。4.You must assemble the electric motor according to the instruction types. The shaft’s diameter of the motor must be grinded according to the standard size of allowable drror. So the customers will grind or cut processing according to the national standard difference with complete leather belts or else parts. When you assemble it, you may push the shaft lightly not use the hammer to hit it or you will demage the parts.
5．为确保设备和人身安全，在电动机通电前，请务必把接地导线连接到电动机的接地螺钉上，并正确接地。接地导线应采用铜导线，其截面积随电动机功率的增加而加大。小功率电动机接地线的截面积应不小于1平方毫米。
5.IN ORDER TO ENSURE THE PERSON’S SAFE, YOU MUST CONNECT THE EARTH CONDUCTOR TO THE LANDING SCREW. THE LANDING WIRE SHOULD BE COPPER. ITS CROSS AREA IS BEING INCREASED AS THE ELECTRIC MOTOR’S POWER IS ADDING. THE ACROSS AREA OF LITTLE POWER MOTORS SHOULD BE NOT LESS THAN 1 SQUARE MM.
6．电动机的安装应保证良好的通风冷却条件，不可用于热晒雨淋的场所。6.INSTALL THE MOTOR SHOULD ENSURE GOOD VENTILATION AND COOLING CONDITIONS, IT CAN NOT BE USED FOR PLACES WITH SUN EXPOSURE OR IN RAIN.
四、电动机接线FOURTH, THE MOTOR WIRING
1、电动机Y/Y2/Y3/YE3系列电动机的绕组引出线为6根。YD/YZD/YDT系列双速、三速及四速电动机根据不同绕组有可能为6/9/12根。1. THERE ARE 6 LEAD-OUT WIRES OF THE MOTOR WINDINGS FOR Y/Y2/Y3/YE3 SERIES. THE NUMBER OF THE LEAD-OUT WIRES FOR THE MOTOR WINDINGS COULD BE 6/9/12 DEPENDING ON DIFFERENT WINDINGS TYPES, FOR YD/YZD/YDT SERIES TWO-SPEED, THREE-SPEED AND FOUR-SPEED MOTORS.

3、按照接线图接好电源线（YD/YZD/YDT系列电动机要按照接线图要求连接好引出线）。外接额定电压进行电动机空载试验。
注意：大极比S3（周期）工作制电动机空载试验时间不宜过长，观察电动机是否有异常现象，否则应迅速断电检查。 3. CONNECT THE POWER LINES IN ACCORDANCE WITH THE WIRING DIAGRAM(THE LEAD-OUT WIRES OF THE YD / YZD / YDT SERIES MOTOR SHOULD BE CONNECTED IN ACCORDANCE WITH ITS WIRING DIAGRAMM). POWER THE MOTOR WITH RATING VOLTAGE THE TEST IT WITH NO-LOAD AT FIRST. NOTE: FOR MOTORS WITH S3 OPERATING SYSTEM, THE NO-LOAD TEST SHOULD NOT LAST TOO LONG. OBSERVING ARE THERE ANY ABNORMAL PHENOMENAS, OTHERWISE YOU SHOULD CUT OFF THE POWER SUPPLY IMMEDIATELY AND CHECK THE SYSTEM.
4、YD/YZD/YDT系列电动机是利用换引出线接线方法来控制转速变化的。应注意以下4点YALX50-2F Y50/9/LX电机：4. YD / YZD / YDT SERIES MOTOR CHANGE THE ROTATION SPEED BY USING DIFFERENT WIRING METHODES FOR THE LEAD-OUT WIRES. PLEASE PAY ATTENTION TO THE FOLLOWING 4 POINTS:
1、在高速切换为低速时，必须在切断电源的同时，断开2Y接线的中性点，以避免在低速绕组接通时引起电源短路。1. BY SWITCHING FROM HIGH SPEED TO LOW SPEED, THE NEUTRAL POINT OF THE 2Y WIRING SHOULD BE DISCONNECTED AT THE SAME TIME WHEN CUT OFF THE POWER SUPPLY, IN ORDER TO AVOID CAUSING POWER SHORT CIRCUIT WHEN THE LOW-SPEED WINDING IS CONNECTED.
2、在高速切换低速的过程中，必须待电动机停转后，才能接通多速绕组电源，以减少对电动机及负载冲击。2. BEFORE SWITCHING FROM HIGH-SPEED TO LOW-SPEED, YOU SHOULD WAIT UNTIL THE MOTOR IS STOPPED, AND THEN CONNECT THE POWER SUPPLY, IN ORDER TO REDUCE THE IMPACT ON THE MOTOR AND THE LOAD.
3、转速切换要注意电动机转向。3. PAY ATTENTION TO THE MOTOR ROTATION DIRECTION WHEN SWITCHING THE SPEED.
4、频繁启动电动机/变频电动机后置***冷风机应单独供电，不可与电动机接线柱接电源。关掉电机电源，应该把风机电压延时5-10分钟，再切断风机电源。4. AFTER FREQUENT STARTING THE MOTOR,FREQUENCY CONVERSION MOTOR， THE FORCE COOLING FAN SHOULD BE POWERED SEPARATELY.TURN OFF THE MOTOR POWER, SHOULD PUT THE FAN VOLTAGE DELAY FOR 5-10 MINUTES, THEN CUT OFF POWER SUPPLY FAN.
五、电动机的运转FIFTH, THE OPERATION OF THE MOTOR
1. 电动机应可靠接地， 接线盒内有接地标志， 必要时可利用电动机的底脚接地。1. THE MOTOR SHOULD BE GROUNDED, THERE SHOULD BE GROUNDING SYMBOL IN THE JUNCTION BOX, THE MOTOR FEET CAN BE USED FOR GROUNDING IF NECESSARY.
2、电动机在额定条件下运转，轴承温度不超过95°，定子绕组***高不超过：B级绝缘80K(电阻法)、F级绝缘100K(电阻法) 2. WHEN THE MOTOR IS RUNNING IN RATED CONDITIONS, THE BEARING TEMPRATURE CAN NOT EXCEED 95 °C, THE STATOR WINDING CAN NOT EXCEED: 80K FOR B CLASS INSULATION, 100K FOR F CLASS INSULATION.
六、针对高原电动机在使用前，如果电动机带有加热带电源接口注意事项：加热带使用环境为摄氏0°以下。环境温度高于0°以上时，可以不使用加热带。加热带是在低温下电动机停机时接通电源，防止电动机冻死不可再次启动。使用时必须切断加热带电源后，方能使用该电动机。以免产生火灾。当电动机长时间停转使用。需要重新使用时，必须提前4-5个小时接通加热带电源，等待电动机预热后方可断掉加热带电源再次启动电动机。SIXTH、BEFORE USING THE HIGH- ALTITUDE-MOTOR, IF THE MOTOR IS EQUIPPED WITH EXTRA POWER SUPPLY FOR THE HEATER BAND, PLEASE PAY ATTENTION: THE HEATER BAND SHOULD BE USED FOR THOSE ENVIRONMENT, WHICH IS BELOW 0°C。IF THE TEMPERATURE OF THE ENVIRONMENT IS ABOVE 0°C, YOU DON’T HAVE TO USE THE HEATER BAND. THE HEATER BAND SHOULD BE POWERED ON WHEN THE MOTOR IS STOPPED IN LOW TEMPERATURE, TO PREVENT THE MOTOR FROM FREEZING DAMAGE THAT IT CANNOT BE STARTED ANY MORE. THE MOTOR SHOULD ONLY BE STARTED, AFTER THAT THE POWER SUPPLY FOR THE HEATER BAND IS OFF, IN ORDER TO AVOID FIRE. WHEN THE MOTOR HAS NOT BEEN USED FOR A LONG TIME, THE POWER SUPPLY FOR THE HEATER BAND SHOULD BE TURNED ON FOR 4~5 HOURS IN ADVANCE, AFTER THAT THE MOTOR IS WARMED UP, THE POWER SUPPLY FOR THE HEATER BAND CAN BE TURNED OFF, AND THEN THE MOTOR CAN BE USED AS USUAL.YDFE50-12F电机

2. 当电动机的热保护及短路保护连续发生动作时，应该查明故障来自电动机还是超负荷或保护装置整定数值太低。消除故障后方可投入运行。2. IF THE PROTECTIVE DEVICES OF THE MOTOR OPERATE CONTINUOUSLY, IT SHOULD ASCERTAIN WHETHER THE FAULT IS FROM OVERLOAD OPERATION, IT CAN BE PUT INTO OPERATION AGAIN ONLY AFTER THE FAULT HAS BEEN ELIMINATED.
3. 应保证电动机在运行过程中良好的润滑，根据运转情况不同每500~1000小时左右，即应补充或更换润滑脂（封闭轴承在使用寿命期内不必更换润滑脂）。运行中发现轴承过热或者润滑脂 YDLX60-12F44电机油变质时，应及时更换润滑脂。更换润滑脂时应清除旧的润滑脂，并用煤油清洗轴承及轴承盖的油槽，然后将润滑脂填充轴承内外腔的1/2（2级）YDLX50-12F电机或者2/3（4,6,8级）。3. SHOULD ENSURE THAT THE MOTOR IS IN RUNNING WITH GOOD LUBRICATION, ACCORDING TO THE DIFFERENT OPERATION CONDITIONS, EVERY 500~1000 HOURS OR SO, THE GREASE SHOULD BE ADDED OR REPLACED (FOR CLOSED BEARING THE GREASE DOES NOT NEED TO BE REPLACED IN THE WHOLE LIFE). IF THE BEARING IS DETECTED WITH OVERHEATING OR LUBRICATING GREASE DETERIORATION DURING OPERATION, SHOULD CHANGE THE GREASE IN TIME. WHEN CHANGING GREASE, THE OLD GREASE SHOULD BE REMOVED AR FIRST, THE
OIL BEARING AND BEARING COVER OF THE OIL TANK NEED TO BE CLEANED WITH KEROSENE, THEN GREASE 1/2 (LEVEL 2) OR 2/3 (LEVEL 4,6,8) OF THE INNER AND OUTER CAVITY OF THE BEARING.
