Motor torque speed curve in the form of a table or spreadsheet

[DMiller01]

I am looking for an example of a 3 phase ac motor torque vs speed curve which includes actual data points that I can enter into excel. It does not have to be for a specific motor but should be representative of a class A, B or C motor. I guess I would prefer a motor 1 to 50 hp motor. I would like to derive some additional curves from the data and a table or spreadsheet be much easier than reconstructing purely graphic curves by hand. Any help would be appreciated.

Thanks

I am using 7.5.2.5 NATIVE on Dell with windows XP OS

Here is a spreadsheet with lots of data tabulated for 60hp, 460vac 60hz, 3590rpm NEMA design B TEFC motor.

Original motor data (hardcopy curves / data sheet) are in tab "Original Data".

The performance data (torque, current, power, pf et vs slip) is tabulated in numerical form in in tab labeled "table".

The other tabs are things used to help develop the tabulated data (fit a model to the data). I think you may need excel analysis toolbak and excel vba analysis tookpak for those other tabs to display and function correctly.

Also, of course there substantial variation in torque-vs speed curves among NEMA design B motors. You can find many example motors and their curves here:
