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]
John
