雙組份打膠機廠家與您詳解關于電機線圈失效七大原因
當電機處于非正常工況(包括電氣、機械和環境方面)時，電機線圈的壽命會嚴重降低。風機盤管故障的原因有:缺相、短路、盤管接地、過載、轉子閉鎖、電壓不平衡、浪涌。下面是各種線圈故障，雙組份打膠機可以幫助您正確識別故障原因(以四極電機為例)。
When the motor is in abnormal working conditions (including electrical, mechanical and environmental aspects), the service life of the motor coil will be seriously reduced. The causes of fan coil failure include: lack of phase, short circuit, coil grounding, overload, rotor locking, voltage imbalance and surge. The following are various coil faults. The two-component glue applicator can help you correctly identify the cause of the fault (take the four pole motor as an example).
1.新線圈
1. New coil
2.缺相
2. Phase failure
缺相是指電源中某一相的開路。主要原因是一相熔斷器燒斷、接觸器打開或一相電源線斷掉。
Phase loss refers to the open circuit of a phase in the power supply. The main reason is that one phase fuse is burnt out, contactor is opened or one phase power line is broken.
在四極電機缺相燒壞的圖片中，電機線圈對稱燒壞的意思是缺相燒壞。當缺相導致星形連接燒壞時，2極電機只有2組線圈是好的，4極電機只有4組線圈是好的;如果三角連接缺相燒壞，兩極電機的2組線圈和四極電機的4組線圈是好的。
In the picture of phase loss burning out of quadrupole motor, the symmetrical burning out of motor coil means phase loss burning out. When the star connection is burnt out due to phase loss, only two groups of coils are good for 2-pole motor and only four groups of coils are good for 4-pole motor; If the delta connection is out of phase and burned out, two groups of coils of two pole motor and four groups of coils of four pole motor are good.
3.短路
3. Short circuit
電機故障是由污染、磨損、振動等原因引起的。
Motor failure is caused by pollution, wear, vibration and other reasons.
4.線圈接地
4. Coil grounding
電機故障是由污染、磨損、振動等原因引起的。
Motor failure is caused by pollution, wear, vibration and other reasons.
5.過載
5. Overload
電機過載會導致電機過載。
Motor overload will cause motor overload.
6.轉子鎖定
6. Rotor locking
這種情況會使電機發熱很多，有可能是由于電機頻繁啟動或頻繁反轉。
This situation will make the motor heat a lot, which may be due to frequent starting or frequent reverse rotation of the motor.
7.三相不均勻電壓
7. Three phase uneven voltage
電壓不均勻會導致絕緣損壞。原因可能是電源不穩定，電線沒有連接好。
Uneven voltage will cause insulation damage. The reason may be that the power supply is unstable and the wires are not connected properly.
注意:1%的電壓不平衡將導致6%到10%的電流不平衡。
Note: 1% voltage imbalance will result in 6% to 10% current imbalance.
8.飆升
8. Soaring
一般是由浪涌引起的。電涌可能由電網、雷電、電容器和其他電氣設備引起。
It is generally caused by surge. Surges may be caused by the grid, lightning, capacitors and other electrical equipment.
