Calculating motor constant
« on: February 14, 2011, 03:41:18 AM »
Not sure if this really goes in electronics, but I don't think it goes in mechanics...

I'm trying to solve for a particular motor's theoretical motor constant, since it isn't given in any spec sheets I could find. Or at least solve for how my torque this motor should be putting out at certain currents.

It's a GWS EM350 motor. 6V, 30500 RPM, Stall torque of 8.3 oz-inches, no-load current of 1.4mA.

I've been using this one tutorial for calculating, theoretically, what this motor should be putting out at so many amps, but it is rather difficult and I'm not sure my calculations are valid. Anyone know how to calculate the theoretical motor constant (oz-in/Amp)? Or does anyone know where I can find the motor constant for this motor?

Any help would be appreciated.
I think the chauffeur did it.

Thanks!

I'll keep this information in mind. Apparently, though, it looks like this motor isn't going to help me after all...but I found some alternatives.
