brushless motor

[yankees2000]

when these come out are people using regular(brush) motors going to be blown out when we race against these guys in competition or will it be equal????

[Distro]

Way i figure it is that brushless motors will have there own class, and most likly regular motors with brushes will slowly dissapear.

[Distro]

One thing i want to know is do these motors get hot? It sounds like they would stay reletivly cool compared to regular brush motors.

i would imagine they would stay perty cool... without the brushes, not as much friction = less heat... but i could be wrong.... these motors look fantastic so far... looks like they don't have any drawbacks...

[FMX_Redth]

these things are looking great... there seems to be no disadvantage over them really...

does neone know what kinda turns they will have? like will there be a stock kind, and mod? or what?

Theres a company in the UK who are supposedly making their own brushless motor/speedo combo. It's modeltech.co.uk.

I e-mailed them about it, and they said they got 60mph in 60 yards uphill!

Thats scary!

The downside is it will cost about £280/$392?

I read in a Aveox flyer that their R/C brushless motor was equivlent to a 14x4 with 3 times the torque of a competition stock motor.

The brushless motors are more efficient, meaning that there will be less energy from your battery lost due to heat. Properly geared, a brushless motor would not get too hot at all. But you know the R/C'ers out there, they like to push things (equipment) to the limits... http://www.rccaraction.com/ubb/smile.gif

These motors have Ernie of trinity so upset that he won't permit the word brushless in any way on the Tech Talk forum. Several of us have been deleted from the Tech Talk B.board just for asking about them. We can talk about any other rc thing except the brushless motor! So we're starting to think that they will be awsome!!!

The new brushless motor will lay waste to most brushed motors. No brushes, no comm, no lathes, no springs and run times should go up as well. May even see 10 min. race heats! The Novak site has some info on them, www.teamnovak.com (http://www.teamnovak.com) then go to the orange room for discussion. The motor dosn't seem to be the problem, it's the speed control to handle the operation of it smoothly!

the major advantage to brushless motors are as follows... less maintance, higher efficiency, less heat...

as far as pure power goes... Novak has released a few numbers... but the numbers they have released look really good, but they won't blow brushed motors out the window.... they should offer about 20% more run time, and perhaps a bit more power... the main thing is that you won't have to work on them all the time like a regular brushed motor... (thank god)

and i surely hope they are not put in a different class... that would be just plain stupid by the sanctioning bodies.. there are already too many classes for the limited amount of people that race... that would be an injustice to spread them out even further...

last note.... i can't wait till Novak gets those motors and esc's to run them on the market.... i don't even care if they are SLOWER, i would still run them because i hate replacing brushes and turning comms every week...

i think brushless motors will be 2x faster then regular motors the reason i say this is because along long time ago car action had the fastest R/C cars and they where all electric with aveox motors i think the fastest was 112mph it was bassed on a Associated chassis. i could be wrong but i know hte speeeds where in the 100mph range. Now that Novak made these bushless motors everyones talking like its this great invetion but aveox made like the first ones but i think they where a little bigger then your average rc motor cause they where meant for rc gliders/planes. If they start using these in races i think it will be a great step forwars for electric rc (yet it well never it will never be as great as smeel of burning nitro) i dont know much about electric rc im 100% nitro the only stuff i know is what i learned from slot cars

I have an older Aveox brushless motor and speed control laying around that I used to play around with in my RC-10 team car. With 6 cells, the aveox was equivalent to about a 9 turn double on 7 cells, and I still got pushing 15 minutes of hard run time on 1400 SCRs (this was years ago). It got pretty warm but not hot after a hard workout, and the torque was awesome. I ran it in the mod class once about 6 years ago at my local track and I was asked not to use it again =)

I've been waiting for brushless motors to take off in the car scene, and I think with a name like Novak behind it more people will be willing to experiment with it and it might take hold. It's so nice not having to worry about brushes and turning comms. All you have to do is occasionally clean the bearings, and if you get sealed bearings, they're almost zero maintenance.

To all,

Do you think all of these motors are going to be exactly the same?

I have absolutely NO desire to own a motor that I have no control over it's performance. This will be worse that our current situation with batteries.

Do any of you race at National level events?

If you do not get help(sponsorship in some form or level) from a major matcher, you have ZERO chance at making the main.

I have assistance in the battery dept, but my brother does not. He cannot get the cells to be competitive. I loan him what I can, but that is not what the cells were sent to me for.

I do not want to see this same situation with the motors.

Brushless motors are a BAD idea.

PS. Almost all drag racers and boat racer have gone back to brushed motors for performance reasons.

[Nairb]

I don't see how you can compare brushless motors to the extreme variance in batteries. I totally understand your battery situation, but brushless motors should do away with extreme motor-quality competition, if anything. With brushless motors, there are no different winding options, high-tech or special brushes, and no advantage from 2 hours maintenance on your motor (comm. cutting, brush replcement, comm drops, whatever). This could effectively level the racing field on their motor options. The only adjustments to motor torque and power would be from ESC settings, which are sure to be far easier than regular motor maintenance and tuning, and the adjusting would probably be free (unless you need a Pit Wizard, which can be shared forever). I see no reason to fret about the vast improvement we'll see across the board from this technology, if widely accepted. They will ensure that DRIVING ABILITY will eventually prevail, not **** motor maintenance or special equipments from sponsors. Don't you agree?

[SirSpeedy]

Increased technology has never leveled the playing field in ANY form of racing yet.

To think that everyone will have exactly the same power output it pretty unrealistic.

OF course their will be production varinace. And it will be noticable at the hihger levels of competition.

I will dig up some of my RC boat mags, and give you some reasons why most of those guys went back to brushed motors.
