Wind power, low-speed electromagnetic slewing bearing diagno
Update time:2012-03-14 09:03 Viewed:次
In wind power plant equipment inspection, it is very important to grasp the information of low speed rotating blade vibration. The rotation of the spindle is about 20 RPM, which is quite low comparing with general rotating machine. Vibration diagnosis is very difficult in this low speed field.
For this kind of low speed spinning machine, electromagnetic diagnosis can be very precise to detect the abnormal situation and accurately capture frequency signal below 1 Hz.
