380 Volt 50 Hz 3Ph. motor operating at 460V, 60 Hz 4

[oldnukeet]

I know that I have seen somewhere recently a fairly simple mathematical model that shows why running a 380 / 50 motor at 460 / 60 is OK. Obviously, it is a matter of maintaining the proper ratio of volts to hertz to avoid magnetic saturation and the resulting eddy currents and overheating problems. But it seems to me that I have seen a simple one page dissertation with all the proper caveats as to what motors are suited to this activity per the nameplate data and most importantly WHY this is electrically equivalent energy flow from the stand point of the motor. Anyone seen the sheet I am referring to or have one themselves ready made? Cruising the Web gets old quick...Thanks!!

Might help in determining what's what.
