无论是哪种伺服电机,使用时间久了,就会产生一些小毛病,这些小毛病要及时检测出来,最重要的是要找到产生这些故障的原因,伺服电机电机维修师才能对症下药,才可以修理好伺服电机,,以下是六种常见的伺服电机故障以及相对应的电机维修方法,详情如下:

  一、电机温升过高或冒烟电机故障

  原因: 1.负载过大;2.两相运行;3.风道阻塞;4.环境温度增高;5.定子绕组相间或匝间短路;6.定子绕组接地;7.电源电压过高或过低

  维修方法:1.减轻负载或选择大容量电动机;3.清除风 道;4.采取降温措施;7.用万用表、电压表检查输入端电源电压;

  二、电机出现外壳带电现象电机故障

  原因:绕组受潮,绝缘老化,或引出线与接线盒壳碰;

  维修方法:对应电机维修方法:干燥、更换绕组;

  三、电机振动电机故障

  原因:1.转子不平衡;2.轴弯曲;3.皮带盘不平衡;4.气隙不均匀产生单边磁拉力

  维修方法:1.校正动静平衡;2.校直轴或更换轴弯曲不严重时可车去1-2mm然后配上套筒;3.校正平衡4.重新调整;

  四、电流三相不平衡电机故障

  原因:1.电源电压严重不足;2.三相匝数不等;3.内部接线错误。

  维修方法:1.检查电源电压;2.更换电动机或处理;3.改正接线。

  五、空载电流偏大电机故障

  原因:1.定转子气隙大 2.定子绕组匝数太少;3.装配 不当

  维修方法:1. 调整并使之减少 2.重新核实并绕制;3.重新装配;

  六、绝缘电阻降低电机故障

  原因:1.定子进水受潮;2.灰尘过多;3.绝缘损坏;4.绝缘老化;

  维修方法:1.排水除潮;2.清理积灰;3.修复;4.更换;

  以上内容全是经验内容整理,伺服电机在日常中应该多去维护和检查,以免出现故障。关于伺服电机平时应该怎样去维护,之前的文章中也有写到,大家也可以参考下。

Whatever the servo motor, the use of time is long, can produce a few small problem, these small problems to detect in time, the most important thing is to find the causes of these faults, servo electrical motor repair to suit the remedy to the case, can only be repaired servo motor,, here are six common servo motor fault and the corresponding maintenance method, details are as follows:

Motor temperature rise too high or smoke motor fault

Reasons: 1. Excessive load; 2. 2. Two-phase operation; 3. Air duct obstruction; 4. Ambient temperature increases; 5. Short circuit between stator winding phases or turns; 6. Stator winding grounding; 7. The supply voltage is too high or too low

Maintenance methods: 1. Reduce load or choose large-capacity motor; 2. 3. Clear the air duct; 4. Take cooling measures; 7. Check the input power voltage with the multimeter and voltmeter;

Second, the motor shell electrification phenomenon motor fault

Reason: winding damp, insulation aging, or lead wire and junction box shell collision;

Maintenance method: corresponding motor maintenance method: dry and replace winding;

Motor vibration motor failure

Reasons: 1. Rotor unbalance; 2. 2. Bending of shaft; 3. Unbalanced belt and disk; 4. Uneven air gap generates unilateral magnetic tension

Maintenance method: 1. 2. When the straightening shaft or replacement shaft is not seriously bent, the car can go to 1-2mm and then match the sleeve; 3. Correct the balance; 4.

Four, current three-phase unbalanced motor fault

Reasons: 1. The supply voltage is seriously insufficient; 2. 2. Three-phase turns are different; 3. Internal wiring error.

Maintenance method: 1. Check the power voltage; 2. Replace the motor or deal with it; 3. Correct wiring.

5. Motor failure due to heavy no-load current

Reasons: 1. Large stator air gap; 2. 3. Improper assembly

Maintenance methods: 1. Adjust and reduce it; 2. Reverify and wind it; 3. Reassemble;

Insulation resistance to reduce motor failure

Reasons: 1. Stator water is affected by moisture; 2. 2. Excessive dust; 3. Insulation damage; 4. Aging of insulation;

Maintenance method: 1. 2. Clean up accumulated dust; 3. Repair; 4. Replace;

The above content is all experience content sorting, servo motor in daily maintenance and inspection should be more to avoid failure. About the servo motor usually should be how to maintain, the previous article has written, you can also refer to the next.
