Why go brushless?

the only decent handwounds that are actually available to buy at the moment are the HH's ....
Wow....you must not look very hard.

I've been running some Fantom 35T Blitz motors in my Bully for almost a year now and they are perfect. The Tekin Pro motors are the same thing. Also, Banzai makes a helluva handwound motor...

I have been looking, but you guys "across the pond" always seem to get in your orders before us Aussies can and then they sell out :ror::ror:

waiting to see what Tekin will do about an issue with my Pro motors before I contact you Eddie ... I got the wrong armature in my can OR the wrong label was applied to the can.. but it said 45T on the outside with a 55T arm on the inside :shock:
 
question:

I thought the discussion was the pros and cons of brushless vs. brushed in crawling applications. I will apologize if there was any misunderstanding, but I posted to show that I indeed have tried a brushless setup, albeit a cheap one, and compared it to what I have previously run in my SCX10 crawler. I haven't tried a high end brushless system...yet, so I have yet to make a definitive argument for myself about which is superior; merely making an assumption or a conclusion that if the cheap Integy, sensorless system works as it does, then surely a sensored system with a nicer ESC costing 3X as much will work better--how much better or whether it's worth the cost is another argument.

As it stands, I've only driven shaft-type crawlers and that my 10 year old Tekin with 10 year old handwound 30-turn spec motor still is smoother than my brand new Integy is testament to just how much more refined brushed--especially handwound systems--are compared to the relatively new brushless setups. I also remember that 10 to 12 years ago, I paid the same amount for said Tekin ESC and handwound motor as I did for the Integy setup today. That said, I make that case, that at least for the application that I currently use it,scale crawling, the difference is so small in terms of precision and driveability, that though I am not willing to recommend the Integy setup for everyone, I WILL recommend that people at least seek out someone that has one and try it out for themselves.

P.S. I have a Holmes Hobbies handwound on order to see what I'm missing. The only other handwounds that I've stuck in my crawlers is a 15 quad, 16 triple, and 13 double, all of which are WAY too fast and can't be geared down enough for me to just not launch the SCX10 into orbit.

hey guys, you both seem to know alot about motors....
what is a handwound? :shock:
 
A handwound is a motor where the copper wire is laid in by hand. There is sloppy handwound, and pattern wound. Pattern winding is best for copper density and power.

oh okay so it is still a brushed motor but the copper coils are laid in by hand? and that it better? that is strange... why is it so much more effective?
 
Its a lot better.....

Pattern winding acomplishes two things....you get the SHORTEST amount of wire on the arm.....think garden hose. The shorter it is, the faster the water comes out the other end. Second, pattern winding makes the segments as symetrical as possible, which makes them need less balancing correction usually.....

A quick example, we used to sell a lot of the Reedy Quad 19t motor. It was machine wound and would typically produce 165 watts or so on the dyno....the best motors topping 170. A handwound one with the same AWG wire would produce 185-190....20-25 watts is a bunch!

All race motors in all forms of electric used pattern wound arms.....

They don't really try or care to pattern wind the current brushless, because the two factors don't really matter at all, especially the balancing part. I don't even know how possible it would be to pattern wind them......

wow okay, that makes sense. thank you."thumbsup"
 
The cost of the machine would be more than 15 years of paying a winder, most likely!


Some brushless motors are pattern wound, but it takes a certain stator design and wind pattern to do so.
 
I saw a machine winder that cost $150,000......and it wound like crap.....it just does not have the ability to do it. I would imagine you would have to make a machine for each wire size and blank size to even come close....and I still don't think it would work very well.

When I was working on my stock motor design with Big Jim, I went hunting for a machine winder. I found a used one that would work, it was $35,000 used.
