Series vs. Parallel

[.30savage]

I installed a couple of Novak 55 Turns in my crawler, now i have been reading about different ways to wire your motors to get more tourqe out of them. Which is the best way to wire these motors for more tourqe? Right now i have positive to negative on the rear motor and on the front axel it is reversed due to the way the mottors are installed to get them to turn the right way. Basically the positive wire is spit going to both motors as is the negitive. My understanding is that if i went to the rear motor first with the wires off of the ESC and then ran 2 long wires out front to the front motor from the rear that this will eleminate rear motor stall ...but does it give me more or less tourqe?

i hope this makes sense

If you wire the motors in Series the system will act as though you are running a 110 turn motor.. which is what you're aiming for in a crawler I imagine. From your description, it sounds as if you are currently wired in parallel which will make your system seem like you are running (1) 27 turn motor (more top speed but less torque). If you ran two wires from both poles from one motor to the other it is no different than how you have it now (with the wires split before they get to either motor. What you want to do for more torque is run the + from the ESC to the + on motor #1, then run a wire from the - of motor #1 to the - of motor #2, then a wire from the + of motor #2 to the - of the ESC.

In most cases where a person would want both motors to spin in the same direction you wouldn't run - to - between the motors, but since you need them to turn opposite you need to flip one motor around.

I think this is correct for your situation. With the exception of reversing motor #2 I'm actually reading directly from pg. 46 in April's issue of RCDriver.

Thank you very much Lessen, it is appreciated. I will let you know the difference it makes.
