HV Maxx ESC
 

Hi


I am wondering whether the HV Maxx Esc can run Novak's line of Velociti Motors , if so which turn motor can I run..

I want to run my old HV esc in my old TA02 and run something along the lines of a 5800 or 5.5.

Cheers

It should be able to. In this case, the ESC would not be the limiting factor, but the motor would be. However, I'm quite sure that the ESC is the limiting factor in the GTB setups, and therefore you would be able to run more voltage with a 7.5 motor (like 3S lipo).

However, don't hold me to it.

Eeeek! No, the HvMaxx controllers will only work with Hv motors. They can be run on 7.2v but there are other factors in the esc programming that mean they would kill a velocity or any other 7.2v novak brushless- thats why those motors have their own dedicated controllers.

here are some esc's that will work w/ the novak velociti brushless....LRP sphere, LRP sphere competition, novak GTB, novak super sport plus.....!

What exactly? I can't see why (in theory) you couldn't run a low kv motor like a 8.5 or 10.5R on higher voltage on an HV. The only biggie I would 1st be worried about is the sensor harness, but that wiring should be the same (as std across brands and regulated by ROAR rules), or easily corrected. I know there is a thermosistor in there as well, but there would be one on both, adn I would think it wouldn't effect programming too much. Logically they would be there same part between the Hv series and velocity series if possible to avoid having to source and supply similar parts. If another brand could run the motor, why couldn't a similar controller within the same brand? Isn't there a crawler motor too? Does that run on the HV or GTB?

Somebody must have tried this before (perhaps not here b4.)
Its been a long time since I looked at the Novaks. The 3.5 has a stupid kv rating, like 10K. I know some motors have diff bearing sizes than others, so I'd pick the one w/ the larger bearings and highest turn if you want to run @ higher voltage. If just @ 7.2V, pick whatever (tho i'd be leary of the 3.5 straightoff.)

Well, I could be wrong I suppose, but the only way to be certain would be:
1. Try it- if it works, great! if it blows up.....
2. Contact Novak and ask.

Novak sensored esc & motors seem to be a bit different & fussy, not like sensorless motors which will work with any sensorless esc in the correct voltage/amperage range.

That's what pretty much what everything comes down to. :)

If you don't want to risk it, sell it and get a MMax or a sensored esc.

HV-Maxx will run any sensored motor. Novak's motors have heatsensor inside motor, so controller will stop working if motor temp exceeds rated limits.

So that's what they do. I wasn't sure if it was a temp compensator for the sensors or for a therm protector like you suggest.:028:

Straight from the Novak website.

My Brushless has an awesome sensor on it.. my index finger.. :)

Were also not supposed to run over 3s on the Mamba...

I was planning an HV controller with one of their slower motors (I think the 8.5) so I could still use my 3s packs, and have the sensored smoothness.

I haven't done it yet (time and budget) but others have. Electric Thunder over on RCZone did it with 12 cells I believe.

Edit: spelling

I hate quoting myself because it looks stupid, but like I said, if it actually works and there are thermal issues, then brilliant- thats a whole load of new options opened up. If however there are more long term issues then we wont know until a little way down the road. The main thing that concerns me is that the normal range of BL motors by Novak are shorter & designed to run on 7.2v. It might be like running 2 540 can motors on the evx at 14.4v; fast as heck but they burn up and die in a short period of time. Good luck though if you try it and succeed.

Yup, 12 GP3300s on my SS5800 (ESC didn't even get warm). That thing SCREAMED in my Rustler. But it did get quite hot (didn't temp it, but it was probably a good 170 after two or three passes out in front of the house). It was also pulling some neat wheelies. Keep in mind this was with a stock rotor (I think, or the velociti rotor; been a while since I cracked that motor open). With a sintered rotor, you'd probably fair MUCH better.

In fact, up until recently, I was running my TT-01 with the SS5800 motor + velociti rotor on the HV ESC. Ran flawlessly; smooth as butter. The ESC was errrr... a tight fit though.;)

Hmm, fair enough then. I see that you used the combo in lighter vehicles, the E-maxx weighs about 9.5lbs stock, and aftermarket anything up to 14lbs+. Sounds like an excellent idea in lighter vehicles when lots of torque isnt required so much.
