The temperature rise limit value of the stator windly (resistance method) is lower than 800C.

 

二、 Y2 系列电动机的结构及安装型式（按表1）P1表格

2.The structure and installation version for Y2 series electric motor （Chart 1）

 

三、 使用

3.Operation

1.电动机安装前应详细核对铭牌所载各项数据是否符合要求，并用500伏兆欧表测量绝缘电阻，其值不应低于0.38兆欧，否则应对定子绕组进行干燥处理，干燥处理时的温度不允许超过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.电动机允许用联轴器，正齿轮及皮带轮转动。但对4千瓦以上2极电动机和30千瓦以上4极电动机不宜采用皮带传动，双轴伸电动机的风扇端，仅允许用联轴器传动

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．对立式安装的电动机，轴伸除皮带轮（或相当于普通皮带轮负荷）外不允许再带其他任何轴向负荷装置。

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.电动机的安装应保证其良好的通风冷却条件。

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

 

5.电动机应妥善接地，接线盒内右方有接地装置。

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

 

6.按铭牌要求准确接线。

6.Connect according to requirements of the nameplate

 

7.当电源相序A，B，C分别与接线柱标志U1，V1，W1，相对应时，电动机的转向，从主轴伸端视之为顺时针，更换电源相序，电动机的转向与原来的相反

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.电动机允许满压起动或降压起动（用电抗器或Y-△起动器），但应注意满压起动时约有5-7倍额定电流，降压起动时转矩与电压平方成正比

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.电动机一般应有热保护与短路保护装置，并应根据电动机的铭牌电流调整保护装置的整定值。

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.当电源的频率与铭牌上的数值偏差超过1%或电压偏差超过5%时，电动机不能保证连续输出额定功率，连续工作的电动机，不允许过载。

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、 维护

4.Maintenance

1.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、纤维等的阻碍。

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.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低。消除故障后，方可投入运行。

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.应保证电动机在运行过程中良好的润滑。

  一般的电动机运行5000小时左右，震动以及噪声将明显增大，检查轴承的径向游隙达到下表数值时，即应更换轴承。

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.电动机贮存运输过程中应保持干燥，避免周围环境，温度的急剧变化，并防止电动机的倾倒或倒置。

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
