(ET) Does anyone have the E-15 and E-20 traction motors electrical specs ? Planning Sepex conversion

[john <johnreinhard rochester rr com>]

Hi all,

I am planning to install a Curtis 1266A SepEx controller into an E-15.

From what I have read, I need the motor specs which describe Armature 
current versus field current, to define and program in a field map.

When I searched Google for this, a long ago (2004) discussion popped up 
where Steve Richardson @ Alltrax asked for same thing to program into 
their controller being designed for the Elec-Trak.

They DID get a reply from Mike Wallace in KY.

Someone also asked that these specs get posted more publicly, but if 
that happened, I did not find them.

Does anyone have this motor info  ?

[Also, anyone have any idea what the parts are inside the custom 
labelled TO-220  devices inside a Curtis 1266A ?  I have a shorted one 
(TO-220), and the marked number does not pop up on Google.  I assume it 
is a 100 Volt (min) High Current FET.  All the gates get fed through 10 
ohm resistors. (the one feeding shorted TO-220 is blown open). The dual 
transistor that feeds resistor also blown, and the Half bridge driver 
that fed that.  But, the CPU still talks to the programmer, So I thought 
it might be worth a try to fix it.  My current plan is reprogram the 
controller to limit amps by 1/6th lower than original 275A max, and 
remove matching labelled device on the other side of the half-bridge 
circuit. I ohmed out the power circuit board and drew the schematic. But 
the logic board has 10x the traces & devices. & I don't really need the 
whole thing (and I don't have a month of personal energy to reverse 
engineer it), just the circuit from that half bridge driver out to the 
power devices. What I really need is a Curtis 1266A service / repair 
manual. But, I might be successful without that... or else generate a 
bunch more smoke ...  Either way, I still the the E-15 motor electrical 
specs]
