Tnx friends for detail explenation

,
Shortly, 3x330A Vs 4x250A have approximatley same efficient and produce the same heat.
If is that so , I will try to take them. I need to see first if guy wants to sell it to me.
I was reading in description of Pauls logic board that logic has 6 isolated drivers for running IGBT-s . So if I want it for DC motor , Paul will put me firmware that runs all drivers paralel with same signal for each IGBT?
How works the current limitation? I have read that logic shuts down when pass the limit of setting current. Can I also limit motor RPM ? max rpm of warp 11 should be 4500 . and max warp voltage is 160V , I will have 220V on batteries. I will need to reduce the voltage on motor output...
How the throttle response ? is it smooth for gentle pushing ?
