Line Frequency or rotational Speed?
1. Using current signature in this case is so useful 2. 50 HZ is rare for electrically problems (personally i never get it in such a case 20 years) 3. finding phase angle of 1X will be so useful (H-V) 4. measure vibration at many locations and match it with Infra-Red to find stator faults- Eng-Ahmed

Vibration level increased after precision laser shaft alignment
Hi Orga78 , It's my first share here , as a designer i use this flex. coupling when no ability to make precision alignment as it can work well with 0.5: 0.9 mm Misalignment which is too large to use laser ,only straight edge and vernier are enough .. BUT the problem in this coupling is to fix...- Eng-Ahmed
