Re: Mini Cim Drive Motors?

We utilized a Magtrol automated Dynamometer setup to test various conditions to make sure the contribution of the mini CIM when combined with a CIM motor was as expected.

My team ran mini CIMs along side CIM motors in our drive gearbox (4 CIMs and 2 Mini CIMs) and they performed as expected.

I hope this sheds some light on the mini CIM performance.

This is exactly how we ran our drivetrain as well. 2 cims + 1 minicim per side. It worked exceptionally well.

In answer to Ether's question: We had them 1:1 but the minicim was unpowered except when we got into pushing matches, so we never heated the minicim up.
