[EVDL] motor controllers - Amp rating is motor current? Also along same lines - motor
I'm looking at controllers for my next large purchase. I have a WarP 9".
Leaning toward the Logisystems 120-144V; 550, 750, or 1000A models.
The Amp rating is _motor_ current for ~10-15s correct?
Since the controller is basically a DC/DC converter, will lead acid
flooded batteries (US Batt 2200XC is what I'm leaning toward) be able
to drive a 1000A controller? My initial guess is yes, since if I'm
delivering 350A from the battery, the motor volts should be ~144V/3 =
48V (from a 144V pack). Is there a minimum motor voltage that is
needed? I.e., will 1000A and 48V to the motor make my tires squeal?
Does anyone have any models of the saturation of the WarP motors?
Once I start accelerating, when does the high amp and low voltage
start to affect my acceleration? Searching the archives, there are
only qualitative statements about the above.
Lastly, is there any advantage to overrate the controller. Longevity,
hot climate, etc.

It may seem like I am doing nothing, but on a cellular level I'm
really quite busy.
