As for the 2 vs 3 CIM Motors, correct me if I am wrong, but based off of this http://content.vexrobotics.com/docs/...otor-specs.pdf
2 Motors at 300oz-in each will draw about 115 amps a piece. 230 amps total.
3 Motors at 200oz-in each will draw about 75 amps a piece for 225 amps total.
Because the curves are linear, total current draw shouldn't matter on number of motors. However, the motors will be rotating faster on the 3 motor setup at ~2200rpm compared to around ~700rpm because each motor has to put out less torque. |
The motors will heat up extremely quickly at those current levels, too. I wouldn't be surprised if some team that doesn't think too deeply into current levels runs a dual or even single CIM setup at 115 amps enough to effectively ruin the entire motor (demagnetization, something melting, etc.)
