Re: Banebot Motor Spec Discrepencies
 
Somewhat related question: Feeding the motor through the 2.7*1 CIM-U-LATOR gearbox gives it a free speed of ~4700 RPM. Is this close enough to the CIM's ~ ~5300 RPM free speed to be useful? I fear that the motor will "fight" the CIMs being 11% slower. Is that a big enough gap that I should be worried?

No, I wouldn't worry. Consider that under load both will be significantly slowed, which means that both will be trying to move your robot or manipulator in the same direction. The only time it really would matter is in the free running state. However, matching them more closely will obviously increase the efficiency of your mechanism.

I've read that comparing free speeds isn't the best way to match motors. Perhaps there is a better way experimentally (put the motor under identical loads and calculate speeds?).

Thanks for the reply. Will the CIM-U-LATOR gearboxes come with our choice of motor already installed? If not, could you outline the procedure for installing them (trying to gauge if it is something we can do at our main shop or would need sponsor help)?

Thanks sanddrag. I removed my post here so no one sees it and uses incorrect info.

Would you please provide a link to this article.

Does anyone know the reduction of the transmissions on these motors, or did I miss them in one of the previous posts?

This thread is about the Banebots motors which do not have a transmission or gearbox provided in the Kit.
