磨床電機響聲主要原因及解決方法:風扇葉片變形或者風扇罩凹陷導致摩擦風扇罩發生響聲。軸承潤滑不良鋼珠剝皮出現響聲。軸承間隙過大或者端蓋與軸承配合間隙大導致定子鐵心與轉子相互摩擦產生響聲。電機帶負載能力降低,有時電機長時間使用后,或電機質量不好,帶負載能力會降低。這里電機的噪音也會比正常時大。電機共振產生噪音,電機在運行時的某一頻段會產生機械共振。這時可以利用變頻器的跳頻設置方法。
 
解決方法:
 
修復風扇罩或者更換風扇葉片。更換軸承。修復端蓋軸承位或者更換端蓋。
 
更換電機。
 
設置變頻器參數,一般變頻器都有“跳頻”設置,其作用是:設置電機共振的頻率,當變頻器運行到此頻段時,跳過此段頻率,避免電機產生共振。
The main reasons and solutions for grinding machine motor noise are as follows: fan blade deformation or fan housing depression leads to friction fan housing noise. Poor bearing lubrication steel ball peeling noise. Excessive bearing clearance or large end cover and bearing clearance will cause noise caused by mutual friction between stator core and rotor. The load capacity of the motor is reduced, sometimes after the electric power is used for a long time, or the motor quality is not good, the load capacity will be reduced. The motor noise will also be higher than normal. Motor resonance generates noise, and mechanical resonance will be generated at a certain frequency band when the motor is running. The frequency hopping setting method of frequency converter can be used at this time.
 
 
 
Solutions:
 
 
 
Repair fan cover or replace fan blades. Replace the bearing. Repair end cap bearing position or replace end cap.
 
 
 
Replace the motor.
 
 
 
Set the frequency converter parameters. Generally, frequency hopping is set in the frequency converter to set the resonant frequency of the motor. When the frequency converter runs to this frequency band, the frequency will be skipped to avoid the resonance of the motor.
