Thank you, where can i buy the wire from in the US?

Does winding two stator arms as a "group" like you show here result in the most powerful configuration? Or is another winding scheme more optimal? This is all very fascinating.

Also, is there a diagram for a "Y" winding/termination pattern somewhere on your site?

[ZuvieleTeile]

Winding in groups of two is the optimum.
Shortest wires, least resistance and if you discover a short during the 1000 Volt test, you have to only rewind this group and not the whole stator.

Has anyone done this motor in 1.5 mm. ? Looks from powercroco's pics that it's doable,

[powercroco]

I tried it.
I gave up because of I feared to hurt the original insulation.
by removing it and using paper and glass plates I think, it will be doable.

no good idea, how the fix the magnet bug.
I would send it back for changing .- such things can kill your esc or your heli (by shooting down the esc)

btw it's really nice, that the henseleit guys compare the motors (quantum and xera) primary by the outside design

[Stolla]

thanks Ralph, would rather go for the thinner wire, since I have 1.32 will it be worthwhile or should I get 1.4?
I will follow your advice and return the motor, will ask them to check the replacement magnets this time. Apart from the mags looks really nice!

[Stolla]

well so far this quantum i's not going as well as planned the multistrand was glued so much it removed a lot of the powdercoating with it. The 1.5 wire is going in but no room to spare, looking at your pics Ralph it seems the gap on quantum slightly smaller than xera or my 1.5 has a thicker coating , so this has been challenging so far, but that's part of the fun right? 1.4 is the perfect fit but I just couldn't get any quick enough so 1.5 it is, hope I don't regret this

[Heli G]

Am watching this one Hermann as I was also thinking of doing it next. Right now I have my own learning curve to work through with a 3226 power house for my 500.

[Stolla]

my advice, get a 4530 scorpion and wind it with paper, or heat it up in oven before removing strands, maybe you're lucky and it doesnt have as much glue as mine. I think this is an early edition, wasn't as nicely made as the one I exchanged it for and came in a white box, not the branded package, must have been a kit motor, but mags are better spaced, mine is done now but had to patch the stator so much it would have been much quicker without the damaged powdercoating, but then that's how we learn I suppose, think it's gonna be a nice motor, it's going into the raptor e720 which had been doing well with the rewind pyro so far

[NRPY]

What's the best way to remove the powder coating from the stator? Powder coating is usually very durable. Do you have to sandblast it?

[Stolla]

I don't think this is proper powdercoating, but I see they use acetone on the mx motors, which seems to have a much more durable coating btw,
But on 1.4 mm. wire the coating can be left on, I would just heat up the wires next time before removal to soften glue and prevent damage to the coating. It's a real nice motor to do and lots of a space under the cap for the twisted wires etc.

Meanwhile I also wound one of these. Next to the HK-4530 the similarity in size is large.
I can confirm the coating of the stator is more delicate than on Align motors.
Unwinding went quite well, I just took my time without any heating. One point on the stator was already damaged and fixed in the factory with kapton tape. I managed to lift the coating on one corner but thankfully nothing more.

I did the same wind as Ralph: 4+5yy in 1.4mm. Indeed 1.5 might fit but then you must get rid of that coating, not only because of space but also the coating is very thin on the corners and more easily damaged with thicker wire.

n spec of partial motors: 515 and 518rpm/V, still have to do the final verification.
Btw the copper increase compared to stock is just short of 60% with this wind.

From the Germans,
Is this worth it?
NO.
The % of power isn't there, the power you see is by changing the Kv up some. But your limit is the magnets, Efficiency is there a gain or a loss? If it's hotter, then you loose.

[Stolla]

Which Germans?

Bit of strange comment this... quite a few corners are cut here.
Have you actually flown it?
Hotter and you loose, why? If resistance is lower but the fill is stuffed to the max of course it will run hotter, why is that bad?
Power increase due to Kv difference is another strange conclusion... A lot of parameters are involved and such phrases only spread confusion.

[Stolla]

Exactly, the russians though think its awesome, the local bushmen dont care, they use the springbuck knock off, handwinded with giraffe sinew, but maybe mine only performs well because of the placebo effect, perhaps we should consider handwind with multistrand.

[HeliFX]

I like hand winding my motors cause it make pretty patterns

[powercroco]

next rewinded quantum 4530.
magnet spacing is okay,
after half an year of use some corrosion on shaft.
winding was well made.
also balancing of can, but to much glue under the magnets, which run to the can bottom.

rewind:
again 5+4 x1,4 YY, winded in 4+3+2 mode.
extra paper into the slots, because of the coating is really thin and weak on this stator.

hardened overall 8mm shaft for a swiss banshee.
stop ring instead of c-clip to prevent the predetermined breaking point.
width flat on the hardened steel was hard work - used dremel and the diamond file.
of course new bearings.

[HeliFX]

Is it fair to say Ralph based on your conclusion that the quantum 4530 and XERA 4530 are the same motor ?

you had mentioned that the Quantum stator is a carbon copy of xera 4530.

would you also concluded that the performances are the same ?

I'm guessing 5+4 T YY you reached a approx Kv 530

[powercroco]

no, it is not the same motor, but similar ... to rs-e (backiron); hacker (stator holder); pyro (fan) and scorpion (magnetic ciciut regarding hammerhead/magnet ratio)

n spec of 5+4 YY is 510/V (post #13) before and 525/V after rewinding.
less than 3% more compared to the original
