How does a messy winding affect motor performance, or doesn't it ??

All my motors seem to appear similar to what you have shown.

I assume the winding is done by hand rather than a winding machine.

Should not make much of a difference in terms of performance.

It's actually largely automated. Drib talks about it in one of his old videos back when he released his own content.

I used to wind my own motors for slot car racing, and later did a few brushless for fixed wing. There were a few makers selling kit motors for home winding as well as ready to use early on.

I have also been involved with winding and repairing huge (half ton plus) brushed motors used in Petrol Electric vehicles in the era 1900-1925 (actually on 40 plus seat double decker open top open stair open cab solid tyred cast wheels buses)

Matching the number of turns is critical, but assuming that they all have the same, and just some are more erratically wound, it WILL make a difference, though in model sizes likely so small it will not really matter much.

To answer specifically HOW, the winding should be at right angles to the laminated pole piece its on to produce the maximum magnetic effect, any angle relative to the pole will affect the result to some degree.

If that kind of winding is done by a machine then why is there no regularity or pattern? Unless they have not optimized the setup due to small production runs?

I have taken several consumer electronics motors apart and the windings are like a work of art compared to what we see in our hobby.

Hmm... Are there advantages to hand wound? I noticed the new f100 motors from tmotor flaunt manual winding as a plus...

To me, a clean winding is just an indicator that the manufacturer of the motor gives a crap about the product they are making. If they take the time to neatly wind the wiring, they are likely not going to force bearings in with a hammer or tap the mounting holes lamely. In terms of performance? If there is any improvement, likely it is marginal at best.

Do you think the hyperlite 2807.5 motor likely isn't great quality then? The messy windings is a photo of their motor

I have not used that motor, a messy winding does not mean that it is a bad motor...but obviously they do not care to pay attention to obvious details like that. I have motors on quads that have messy winding and they have been fine...and I have had ones with messy windings and they have turned out to be garbage. RCX used to hand wind their motors and they were flawless. At some point they started producing motors with sloppy workmanship in that area, but the motors still perform like the old ones I was used to. Winding condition is not an end all indicator...but it is pretty obvious when a manufacturer discounts the impression clean windings give is all.

I was curious and looking at my various quads, and all the motors with multi-strand windings look like a mess, and all the single-strand wiring looks really neat.

The photo appears to be single strand winding though (the first one I uploaded ). I think I may stay away from them just for that reason. Sad but if they don't even care enough to have nice windings in the advertising photos, then I'm not sure it's worth the $4 savings per motor over the nicer motors...

Look at these motors.
All look the same. some more notchy. Some have ugly flat magnets. Small differences add up.

winded by hand is declarated by the manufacturer, it counts as a higher quality.
from performance focus in racing, handwork doesnt perform better. the difference between hand and machine is more of a quality control, handwork does receive human attantion.

i dont believe in an issue from the first picture, maybe a question could be how thick a winding should be for the best performance or if two thin windings could be better.
a thin windinig will always look cleaner and its more work, but is it better?

Interestingly enough, I realize the windings in that Hperlite 2807.5 motor look exactly the same as the Brotherhobby 2810 motor. I wonder if that is a coincidence.. hmm...  --- it looks like the same motor with a smaller stator, but it is rebranded maybe. 

Maybe I'm making something out of nothing. I dont think anyone would question the quality of bh avenger big block motors. I guess it is just bothersome to see things that don't look purposeful.
