maximum temperature on a bearing on electrical motor
maximum temperature on a bearing on electrical motor
(OP)
I have a 3.5 MW motor, syncronous, with two sleeve bearings, (zoelern manufacturer) and i have temperatures up to 93 º C, and the manufacturer of the motor, says me that i could put the alarm temperature on 95ºC and the stop on 100 º C, this seems to be too high, does somebody knows about some standard that talks about this, cause i´ll like to have something like an standard for discussion.
thanks
thanks

If it has auxiliary cooling, then maybe the values are correct.

Is this a new development or does this motor have a history of such high temps ?
Even if the manufacturer says 95 deg C is the alarm, 93 deg C is too close for comfort.

What is the temperature you are measuring, the oil or the white metal ?
