Model GE 752 Shunt Standard Torque

12/13/2016 10:08 AM

Dear All,

I'm trying to model a GE 752 shunt standard torque in ETAP, but I can't find the typical data for this kind of motor.

Anyone have this information?

BR

And even more on Pages 29 & 72, nice set of documentation, don't see them like that any more.

You should be able to back calculate it from the impedance values on Page 72, and using the resistance values given earlier. There is impedance for the field also given, also the resistance.

I'm just looking again, and I think I mistook the resistance values for impedance, not sure why, or saw Impedance Test but didn't notice the units or the fact that it is only the fields.

However, the impedance at 60Hz is given for the fields, R equals E/I. I suspect that the armature impedance is too low to measure reliably, so can safely be ignored, or can be approximated by a typical X/R for a dc machine, not that I have one. The only X/R that I ever use is for transformers at approx 12, but this is nowhere close to that, maybe 1.6 to 1 at 60Hz, as a SWAG.

I believe that the Commutating fields are the fields in series with your armature, not the shunt field of the motor, which I think is called Exciting Field.

So your impedance at 60Hz would be 0.37 ohms to 0.48 ohms, not sure just what part of the coils assembly the retainers are.
