I have lots of motor spec sheets without speed / torque curves. In most
cases there are several versions of the same static torque design, where
they trade off current for inductance. I realize that higher inductance is
going to cut into the speed / torque curve at the high end, but I don't know
how much. Does anybody have any equations or predictions for this?
Would a straight linear model work? What I'm thinking of is looking at what
the RMS current of a square wave at the bus voltage would provide with the
resistance and inductance of the motor in the given time for a single pulse.
Is that an accurate model? Are there any simulation programs I can run
which take motor and voltage parameters as inputs?
Any help would be appreciated on this.
