Re: Do CIM elevator motors overheat?

Two years ago we were using a single miniCIM for our lifting mechanism to climb the tower. During extended testing, (lift, stall for 5-10 seconds, pause for a minute as we debug, repeat) it got extremely hot, and as a result we added a second miniCIM. The motor itself never burned out. Also, the design was worked to minimize stall time. During competition it was never stalled for more than a second on each level.

The CIMs can take a while lot of abuse, but it's better to have a design that does not involve stalling the motor. It may work just fine for a few matches, but if you keep stalling the motor it may eventually fail... Probably in the eliminations when match turn around is so short.
