Re: pic: Tight fit!
Ah - the curse of the EE on a robotics project. "Make it work beautifully," say the project managers, "make it do cartwheels. But make it fit in a 4 inch cube."
My gut says that you'll have plenty of air flow. Sure it's not a "best practice" to put something directly above a cooling fan, but what is integration if not a compromise?
One more thing - "hot CIM motor" temperature is nowhere near "hot FET" temperature. The core of the motor would melt before it got to the point that the FETs wer getting hotter from the air blowing past the motor. Or perhaps I'm exaggerating.
