三、 使用

3.Operation

1.電動機安裝前應詳細核對銘牌所載各項數據是否符合要求，並用500伏兆歐表測量絕緣電阻，其值不應低於(yu) 0.38兆歐，否則應對定子繞組進行幹燥處理，幹燥處理時的溫度不允許超過120⁰C。

1.Before installation ,users should check the data loaded on the nameplate and measure the insulation resistance with 500V insulation resistance meter ,the value should not be lower than 0.38MΩ,otherwise the stator winding should be dried in a temperature lower than 120℃

2.電動機允許用聯軸器，正齒輪及皮帶輪轉動。但對4千瓦以上2極電動機和30千瓦以上4極電動機不宜采用皮帶傳(chuan) 動，雙軸伸電動機的風扇端，僅(jin) 允許用聯軸器傳(chuan) 動

2.The motor is allowed to rotate with coupling ,spur gear and belt gear.But the 2-pole motor with 4KW or higher and 4-pole motor with 30KW or higher should not use belt gear.For the fan terminal of two-shaft extension motor ,only coupling mode is allowed .

3．對立式安裝的電動機，軸伸除皮帶輪（或相當於(yu) 普通皮帶輪負荷）外不允許再帶其他任何軸向負荷裝置。

For the extension of standing motor,only the belt gear (or like the common belt gear load ),ratherer than other bearing load devices is allowed .

4.電動機的安裝應保證其良好的通風冷卻條件。

4.The installation of motor demands the good ventilation and cooling .

5.電動機應妥善接地，接線盒內(nei) 右方有接地裝置。

5.The motor should be well grounded ,and the grounding devices are on the right inside the junction box .

6.按銘牌要求準確接線。

6.Connect according to requirements of the nameplate

7.當電源相序A，B，C分別與(yu) 接線柱標誌U1，V1，W1，相對應時，電動機的轉向，從(cong) 主軸伸端視之為(wei) 順時針，更換電源相序，電動機的轉向與(yu) 原來的相反

7.When the power phase A,B,and C correspond respectively to the ground poles U1,V1 and W1,the rotation of motor from the direction of extension terminal of main bearing is considered as clockwise ,if the phase sequence changes ,the rotation of the motor is opposite to the original .

8.電動機允許滿壓起動或降壓起動（用電抗器或Y-△起動器），但應注意滿壓起動時約有5-7倍額定電流，降壓起動時轉矩與(yu) 電壓平方成正比

8.The motor allows full-voltage starting or decreased-voltage starting (with reactor or Y-△ starter),but it should be noted that the rated current in the full-voltage starting is 5 to 7 times higher and that the rotation distance forms direct ratio to the square of voltage in the decreased-pressure.

9.電動機一般應有熱保護與(yu) 短路保護裝置，並應根據電動機的銘牌電流調整保護裝置的整定值。

9.Normally ,the motor should have heat protection and short circuit protection devices ,And the setting values of the protection devices should be adjusted according to the nameplate .

10.當電源的頻率與(yu) 銘牌上的數值偏差超過1%或電壓偏差超過5%時，電動機不能保證連續輸出額定功率，連續工作的電動機，不允許過載。

10.When the deviation between the power frequency and the value on nameplate is over 1% or the voltage deviation is over 5% ,the motor can not guarantee the consecutive output of rated power ,and the motor in consecutive working is not allowed to be overloaded .

四、 維護

4.Maintenance

1.使用環境應經常保持幹燥，電動機表麵應保持清潔，進風口不應受塵土、纖維等的阻礙。

1.Keep the motor dry in the using convironment ,the motor appearance should keep clear ,the ventilator should keep from dust ,fibre and so on .

2.當電動機的熱保護及短路保護連續發生動作時，應查明故障來自電動機還是超負荷或保護裝置整定值太低。消除故障後，方可投入運行。

2.When heat protection and short circuit protection devices occur some movement on the motor ,please check whether the breakdown is from the motor or overload or lower of the setting values of the protection devices ,after trouble-shooting , then could let the motor run .

3.應保證電動機在運行過程中良好的潤滑。

  一般的電動機運行5000小時左右，震動以及噪聲將明顯增大，檢查軸承的徑向遊隙達到下表數值時，即應更換軸承。

3.Keep good lubrication during the running of motor

The vibration and noise of motors will increase obviously after running for about 5,000 hours .Check the radial internal clearance of bearing .When it reaches the values in the following table ,the bearing should be changed immediately

4.電動機貯存運輸過程中應保持幹燥，避免周圍環境，溫度的急劇變化，並防止電動機的傾(qing) 倒或倒置。

4.Keep the motor dry during storage and transportation and avoid sharp changes of ambient environment termperature and the incline or inversion of the motor
