Hi!
Does anyone know where can I find the thermal time constant of electrical asynchronics motors?
thanks in advance.

RE: thermal time constant
That constant will depend on the motor materials, current pattern and cooling system. Could be quite different for different brands.
RE: thermal time constant
I know wath you say, but the manufacturer dont want to give that information because it's their "know how".
That's why I was looking for another way to find that information.
Thanks again

RE: thermal time constant
This value is different for every manufacturer and model.

I had posted some shutdown temperature patterns for motors at our plant a few years ago... might be of use as "typical" values. Unfortunately the search feature at this site does not allow you to combine different criteria such as posts by a specific user containing a specific keyword (pick one or the other... keyword or user). I have too many posts to look through them all.
