I am almost to the point of working on the electrical portion of my junk
yard reject (JYR) when I saw Daniel Gallaher post on electrical circuits. I
started to look at my references and saw some discrepancies in the way the
controller is connected to the motor.
First of all I have a Curtis 1231C-86 controller which will be connected to
a NetGain 9 inch motor all installed in a rear wheel drive JYR or more
commonly referred to as a Fiero. The NetGain manual indicates that for
Counter Clockwise rotation which is what I will be using that Terminals A1
and S1 are connected together and that Terminals A2 and S2 are input power
terminals. But if you don't like that arrangement you can also connect A2 to
S2 while connecting A1 to one power terminal and S1 to another power
terminal. This is another reasons for choosing Mechanical over Electrical
engineering.
Now then the Curtis manual gives a couple of Typical wiring Diagrams which
show that if you connect motor terminals A2 to S2 or A2 to S1 depending upon
your desired direction of rotation that this pair is also connected to the
A2 terminal of the controller.
However, in reviewing Bob Brants book page 218 ( Figure 9-7 Electric vehicle
basic wiring diagram) which also looks like a Curtis controller just from
the drawing, terminals A2 and S2 on the motor are connected together but A2
on the controller is not connected to anything. Also the simple wiring
diagram shown in "Build your own Electric Car or Truck" by Les Oke and the
example wiring diagram shown in the
http://www.diyelectriccar.com/forums/showthread.php/ev-information-669.html
which
also reference a Curtis 1231C controller Terminal A2 on the controller is
not connected to anything.
I must presume that the Curtis Manual is correct in the connections but does
anyone know why these other sources all do not connect the A2 terminal on
the Curtis to anything.
Thanks
