Hi,

I'm wondering about running two brushless motors on one brushless ESC, can it be done or do i need two ESC's?

Also any advise on high volatge ESC's would be great help.

All ESC's i can find seen to be for 7.2-8.4v. I'm wanting to use a much higher voltage than that so any suggestions would be great.

The only one i can find for high voltage is this one:
Novak HV-Maxx Brushless Motor System

It doesn't say in the description how much voltage you can use with it though? Anyone know how much voltage it can take?

Any reply would be great.

Thanks.

i'm not really up on brushless technology, but i would say you need 2 speedos

Obviously the HVMAXX will work and go somewhere upto 14.2 V. Probably more.

Thought Matt would have known the answer to that !!!

As for normal ESC's... I would say, yeh, you'd need 2, you'll probably Thermal or even Blow Up if you just use 1.

cheers russ, sorry STR33TRAC3R was a lazy reply by me there, i was rushing out to get some drifting in before it rained :D

as russ says its rated to 14.4v but can run more! but the optional novak fan kit is essential if you wanted to run 16.8v

not sure if you can run 2 motors off it

Thanks for the reply, i want to run at least two 11.1v lipos so around 25v minimum.
I was hoping to run three but two should be fine to start.

Any ideas why 1 ESC for 2 motors wouldn't work then?
I'm guessing you said that it may thermal or blow up because it would get to hot. Why would that be if i was using voltage within the guidelines given by the manufacturer of the ESC?

Where did you get the information saying the HVMAXX can run between 14.2 and 16.8v?
If you could please post a link to it that would also be great help.

Thanks.

few guys on traxxas forum running 16.8v

also see here...

http://www.teamnovak.com/products/esc/3220hv_esc/index.html

"The HV High-Voltage Brushless ESC that is included in the #3020 HV6.5 and #3021 HV4.5 Brushless Systems accommodates 6-14 Ni-Cd/Ni-MH cells (7.2-16.8 volts) or 2S – 4S Li-Poly cells"

Thanks a lot,
Any chance you could tell me the link for the forum where the guys are running 16.8v.
I could hassle them with some questions as well. :D

sure mate its the e-maxx section you want, heres the link...

wow Matt is being useful!!!!

The motors used in a Emaxx are 550 right, Normal sized motors are 330? Is that right.

540 in tamiya 1/10 etc
380 in 1/18 scale mTs etc
:thumbs_up:

It say's on the Traxxas site that the E maxx comes with twin 550 motors.
Are they slightly larger than normal motors then?

Is say a modified checkpoint motor a 540 then?

550s are the same external size, 300-399 are 300 class motors same size outside
400-499 400 class
500-599 500 class
I have a Graupner 600 and thats slightly bigger externally than a 540.

550 titans
:thumbs_up:

550's are actually a bit Bigger than 540's.

But it's in their Length.

They offer More Torque over 540's and improve on that even more by having that piece of metal wrapped around the can.

Yes a Checkpoint is a 540. As is any motor that we use in 1/10th Scale Electric.


:thumbs_up: :thumbs_up: :thumbs_up:

Is the extra length the buult in fan housing?

That is extra admittedly, but..

The Stack is Longer as well, etc.

It is a Bigger Motor than a 540.


:thumbs_up: :thumbs_up: :thumbs_up:

What is it that determines the number given to a electric motor?

Yeh, basically if you look at the Cans, they should be the same size if they are in the same Series, I Think.

With the 550, it's just Longer, and i think thats how some of the other's work as well.


:thumbs_up: :thumbs_up: :thumbs_up:

So it's the can size that determines the number?
Which part of the can is 550 then or 540? Is that length? 5.50cm long and 5.40cm long? :unsure:
