motor parameters

Hi!
I´m looking for any webpage were I can find examples of the equivalent circuit parameters, but I cant get them.

Does anyone know were can I find them???

Thanks in advance.

Martin

Try the Baldor web page and/or other motor manufacturer web pages.
Also check-out the NEMA web site.

thanks waross, but the motor manufacturer dont wanna give that kind of information. I tried with siemens, ABB, Schneider and nothing happened!
So I was looking for any webpage that has laboratory tests.
thanks again

Hello Martin

You could also look at the default parameters in open loop vector drives as an indicator. The drives have a look up table based on typical values which are then tuned by the setup mode and can be programmed by the operator if they know the actual values.

I assume that you are discussing asynchronous motors. In that case, you might try to calculate the parameters from the "name-plate" parameters (voltage, power ,slip, etc). A suitable program can be downloaded at

(it usese some simplifying assumptions).

Motor parameters can be found at, for example:

small motors

larger motors

I don't know of any web source that lists induction motor parameters. If it's any use to you, I have some manufacturers parametric/design data on a couple of motors, it depends what you want.
