Parallel Wiring

[Crawly]

Just a quick question on parallel wiring for a clod. I've read of two different ways to wire in parallel. The first is to go from the ESC to the rear motor and then from the rear motor to the front. The second way is to wire both motors together and then wire in the ESC to the middle. Is there an advantage to either way or does it really matter?

the first method is called series wiring, will give you less power and more runtime. parallel wiring gives you more power and less runtime, assuming your esc can handle two motors. series wiring is okay on just about every esc.

If you go with that first setup, more power will go to the rear motor, since the front one have 3 time more wire to go through. The second setup will give equal power front and back. Its up to you to decid which you like.

For microgoat, he means wire the motors in parallel, then attach the speedo to just the rear motor, this is a parallel wiring.

(front motor)======(rear motor)==[speedo] setup 1

(front motor)===[speedo]===(rear motor) setup 2

ive tried both methods, and i cant tell a darn difference. wiring to the rear motor first is negligable for adding resistance to the front motor, and doesnt really do much except use more wire.

i like to wire as cleanly as possible, so i run two wires connecting the motors positive to positive and negative to negative. in the middle (or wherever the esc is) i tack in a deans plug. easy and clean.

yes deens plugs are they way to go they look very professional if you do them right... and it really shouldnt have much difference how you wire them... the only way u would c a difference in motor rpms would be takin the positive on the esc to + on rear motor then from the - on the rear go to the + on front then the - on the front ... so its just like a big loop of motors...

Parallel is parallel...period.

Electrons don't care how you wire the motors if the end result is a parallel circuit.

You're not going to change the laws of electricity by creating a different type of parallel circuit. It's still parallel.

I've tried it myself, wired the motors 7 ways from Sunday....bottom line is that parallel is parallel. Sure, there's a minute amount of resistance in the wires, but I challenge you to measure the difference with a multimeter. You'll measure more resistance at the connection between the meter's test leads and the cable than in the cable itself.

Very Very good point!

So the myth about wiring the rear motor first to help with the infamous "clod stall" is more of a waste of wire than anything else? How much of a difference is there between wiring in series and parallel? Is it a big enough difference to change from one to the other?

 

[JasonInAugusta]

As far as I see it, it's exactly that...myth.

Like I said earlier, you'd think that wiring the rear motor first would help, but you have to consider how minute of an amount of resistance we're talking about here. It's negligible.

Two 55 turn motors in series is the same load on the speed control as a single 110 turn motor. (resistance in series is additive)

BUT in series voltage is also additive. (sum of the voltage drops equals the applied voltage) So each of the two motors will see half of the applied voltage, 7.2v.

In parallel the two 55 turns will be the same as a 27.5 turn motor (near the stock turns of a 27 turn "kit" motor). This means more current flow.

In parallel voltage is constant...so both motors will see the applied voltage, not a portion of it.

Power is calculated by multiplying current and voltage.

In parallel you have increased current and higher voltage to each motor.

More power!

 

[JohnRobHolmes]

in series, if one motor stalls (increasing resistance), the other motor gets more appied voltage. for rock crawling it basically sucks because the stalled motor gets skipped over. the electricity will go to the path of least resistance.

in parallel the motors both get the full applied voltage. they act independent of each other, and will pull the amperage that they need for full power. its how you get out of the "dreaded" axle stall.

honestly, i like clods because of the axle stall. it keeps the truck from flipping backwards sometimes. After driving one with independent front and rear throttles i realize fully what the potential is for the design. sometimes a faster rear tire can get you up sections. sometimes front dig can get you unstuck from a rock, and front pull can get you out of a crevace. its very useful, but not as useful as independent 4 wheel drive!

Thats funny JIA!! Really!

John your PM box is full.

 

[nd4spdbh]

dude 4 wheel independent drive would be freakin tight... i have always loved playing around with my friends clod that has the front are rear on 2 different speed controls! its some pretty crazy stuff!

Thanks for the replies guys. I didn't really think there would be a difference, but now all that info just confirms it.
