That's why I originally measured just the AC input. I know what the Fluke's algorithms are for a simple 60 Hz sinusoidal waveform. I don't know how it interprets a pulse width modulation waveform
As for rewiring to work on straight DC and measure that current.. I am not up for doing a science experiment here, and I am not sure it will give useful information anyway. Other motors have a higher Nm/A (torque per amp), so that seems to me to be the most expedient approach.
Besides John, I remind you of your tagline

A rectifier is 4 wires …6 in your case,….swapping motors is gut the tool box time ….I’d opt for the easier approach…..this will tell the story for sure…..tossing motors at it in hopes of a solution seems like dart board diagnostics…….especially given the testing you’ve already gone through…..
