Gearing That Cannot Overcome Static Friction

[Veselin Kolev]

Oh its pretty hard to make a robot not move because its so geared up. Stall torque is so high that it creeps a bit and then kills your breakers. Ive tried it, direct driving 4 CIMS to six inch wheels. It's actually pretty funny to see, large buzzing noise from the motors vibrating at close to stall. Then the magic smoke comes, and you hope you didnt use competition CIMs.

It is a lot easier to stall out a gas engine because the torque curve tops out at close to max RPM, while an electric torque curve tops out at zero RPM.

With that said, anyone who gears up a robot so much that it doesnt move from standstill will probably never get their robot going fast enough to maintain any kind of speed at the highest gear.
