I just got off the phone with Banebots.
They don't have (or won't reveal) the inductance of their motors.
Would someone with access to a scope be willing to run a short test on an RS775 with the rotor locked and powered by a Black Jag at 20% PWM output, and post the trace of voltage and current at the motor?
A cruder (but still useful) test would be to hit the locked-rotor RS775 with a 12V step input of duration at least 6 milliseconds and record the voltage and current trace.
I can get the inductance from the curve.
It may be necessary to run the test with the rotor at slightly different rotational positions because of the brushes.
I do not have access to the necessary test equipment or I'd do it myself.
The inductance of the motor is a necessary piece of information to answer some questions that have been asked about power consumption of the RS775 under various stall conditions.
