Good suggestions. Our previous tests (see
earlier post on CIM temperature rise at peak mechanical power) included thermocouples at four locations: brush guide, internal air, motor case, and lab ambient. And I agree a lighter load point will illustrate the effect of differing free speeds when the CIM and mini-CIM share load at 1:1 gearing.
PM me if you want to come by the lab when this test set up is ready.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
