Does anyone know where I can get the torque-speed curves for this years motors? Thanks for any help,

Well I know you can get a graph of the torque-speed curves in the rule book (look under spec. sheets). This section of the rule book will also give you information about the other motors (stall torque, speed) these have no graphs.

Check out Dr. Joe's whitepapers on this site. Good Stuff.

The Motor Calc Spreadsheet on our Whitepaper page will
make the Speed Torque
Curves for the motors given a few bits of data.

Joe-
Do you have any real curves for the fisher price, Van
door, Bosch/Van door, drill motors w/or without gear
box, or the new Belimo motor. If so, would you willing
to share that information?
Having worked at ITT Automotive, I fugure you must have
a dyno on-site that you are using to get real
speed-torque and current torque curves. Please let me
know. -Joe

With regard actually measuring the speed torque curves
of the motors in the FIRST kit, we have never bothered.
We have designed with the theoretical values (using
the published Stall Torque & Free Speeds). This as
always been close enough for us. In practice, the
results have matched the calculations close enough for
us to trust them.
