Go to Post We have donut eating contests to see who has the best legs. We paint our pigs. We argue about which time zone we are in. About 400,000 of us gather together to watch cars go around in a circle. We also build robots.Yep, our cultural norm is a bit different. - Andy Baker [more]

The info is in the APP-NOTES

Below is the typical information given in the Application Notes (that are part of the RULES by the way -- please read them!):

Quote:
Application Note: Globe Motor
Specs:
1. Stall torque at 12 Volts: 180 in-lbs
2. Stall current at 12 Volts: 20 Amps
3. Free Speed at 12 Volts: 45 RPM
4. Peak Power at 12 Volts: 23 Watts (mechanical power, not electrical power)
With the data given, you can generate the motor curves you are interested in. Use the spread sheet in the whitepapers section of this web site if you need help generating the plots (my motor calc spread sheet would like to have free current as well as stall current, but for our purposes you can get away with entering zero or 0.5 or some other estimate with little ill effect).

I hope this helps.

Joe J.
