Large CIM Motor Bias

[Ceal Craig]

Has anybody seen a notable amount of motor bias on the large CIM motor? we had a mockup for our shooter with the CIM mounted turning the wheel one way (ball exiting the bottom) and decided to have it exit the top instead, but with the motor mounted in the same manner, basically.

We *think* we are seeing a much reduced RPM (say 1500 instead of 2000). Not certain.

Any body seen anything like this on the new Large CIM?

Thanks for any input!

Haven't tried it, but if you think about it, it'd make sense. We're used to thinking of CIMs having very little bias, but those were for winches, which need to be equally powerful in both directions. This one is for minibikes, and, like the drill, most people drive their minibikes in the forward direction. So, this'd make a lot of sense to me. Does anybody have some hard data (quantified)?

I just measured and found a 2% difference.
