Re: paper: 4 CIM versus 6 CIM theoretical calculations
I was using 0.39 ohms for the motor branches circuits, as I computed the CIM resistance separately. But your results are close enough, and just as valid as my assumptions. You come to the same conclusion that the actual system can't deliver the full stall torque to each motor in either the four or six CIM drives.
Once you get moving the six CIM drive will deliver 150% of the torque; and the acceleration, and time to speed will be much better. The brownout margin is much less, so there's no free lunch.
