A few links worth looking at:
Here's a link to some details of how CIM motor's
heat up when loaded to their maximum mechanical power.
Here's a link to some measurements my lab made of CIM motor
starting current. Special thanks to Russ Ether for his help with that testing. Here's another link to his
white paper on how several FRC legal speed controllers limit the CIM motor's starting current.
Here's the link to Al Skierkiewicz's thread (mentioned above) on
failure of a CIM motor due to extended, hard practice driving. Don't try this at home, or if you do then plan to replace the motors before your next competition.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

We'll defintely be working on both the balancing 2 wheel robot, the 6 legged robot, and the wood chassis 8 wheel drive robot ideas this fall. - MrForbes [more]
