Well, I am interested in building a chart to compare torque @ rpm for different motors available for airsoft use.

My problem is lack of training in this field. I believe that attaching the motor to a spindle and winding a string attached to a weighted lever until stall could measure relative torque @ 0 rpm. I would prefer to be able to measure torque @ any rpm.

Is this possible at a reasonable expense? Any doctors have the training to build a dynamometer for our small motors?

Thank God! Seriously, I have been wondering why manufacturers and dealers dont list this info. While ounce-inches and pound-feet may not mean much to the layperson, numbers DO. I used to work on R/C cars growing up and the big marketing thing for these electric motors in the 90s was to call them single, double,triple, quadruple or quintuple-wind motors, referring (I believe) to how many times the wires were wound around the rotor magnets.

Now if you were to go on evike.com or airsoftgi.com, they simply list motors in the manner you described above! And every manufacturer has their own brand which they claim is awesome, but it never gives exact specs and certainly not numerical values. High torque, high speed or some new-fangled motor which claims to do both, are all I can find. There must be a simple physics model that can help help calculate motor rpm and torque with and without load.

Thoughts?
