Re: CIM motors
As promised, here is some very raw data. This is a comparison between the CIM and Mini CIM driving the same system.

In a nut shell, the the Mini CIM draws more current at the same voltage.

Using the CIM's current draw (19.4 amps) at 10 volts, the CIM's speed can be estimated.

3726 RPM at 10v. Excellent, that confirms that it is operating exactly in the range we expected it would, 2K-4K RPM. It also confirms the video was accurately representing these numbers.
