So the car software just won't work on the airplane hardware -- different type of back-EMF sensing.
To run car software on the airplane power boards, I'd have to design a new control board for them.
But airplane power boards are really designed for airplanes - - not for the types of loads that cars put on a controller -- our car controllers ALSO use very heavy copper (6/6 on the MM, 6/6 + 4/3 on the MMM) but are designed to handle short term overload currents better than the airplane controllers. The MMM has the same number of FETs as the Phx-80, but handles over double the surge current and over double the continuous current. Part of that difference is the fan/heatsink, but the majority is the copper layout and current path copper total. The Phx-80 was designed to be light weight and compact, the MMM was designed to handle serious current surge and power. |
Ok so it has to do with the back-EMF mainly and then the amount of copper. So the SHV is the same way? Now what if the intended use for the HV and SHV controllers were to just lower the amount of AMPs used? Could it be possible for just a simple car software?
