it's common to put the full load speed on the nameplate ... 10 RPM slip is pretty good. So we'd be looking at multiples of 0.89 to 0.90 kCPM ... I don't know the accuracy of the markers, but the 13.89, if a little off, COULD be a 15x or 16x motor speed. That conceivably could be a ball or roller bearing. Does this motor have plain or antifriction bearings?Thanks. This motor's is 890RPM. (which is kinda odd, I would assume it's a 8-pole machine, then rpm 900). I will have to verify when exact and at where this vibration was taken.
You misread ... I said I've **NOT** done enough to ...You said you've done enough to know what the lamination vibration characteristics would be, so could you share some light on that?
sorry.
