Mr Mohammed,
Like your analysis, sequence presentation in knowing the unknown frequencies.
Secondly, normally we get PPF, RBPF etc in many motors and also with additional inputs from MCSA. But identifying faults in rotor bars correctly need serious analysis involvement. Nice and all the best for your next predictions. Now there is a need to go for RCA.
nice one!
How many rotor bar is this motor? Did you see that freqeuncy?
NICE JOB Muhammad and good analysis
Hi all,
I have enjoyed the analysis and it certainly is a very sophisticated approach.
A couple of questions, and apologies in advance if they were staring me in the face the whole time but;
1) how was sync speed established at 1495RPM?
2) same for actual speed at 1488rpm? M1H run speed states 1503rpm
Thanks in advance. I am still new to VA but definitely willing to learn.
Thanks Mohammad…Your report is very helpful for me in recently facing a same issue.
