Aluminium Shaft - I use the pushrods from older types of car engine - very strong Aluminium! Mostly these rods are at 9 up to 13 mm diameter with lenght of 200...300mm. Easy to machine on the lathe. Making my rotor bell went arduously - I did not found the right sized tube or any else steel bar, but found an 50mm OD piston pin of some very large diese engine. I heated it up to 1000C degrees and left then slowly cool down - next morning it was possible to turn on the lathe.

18/4 winding scheme


hi Ralph,
OK, Seemest you und Kameraden from RC Line Forom have not understand my Winding Scheme. At least 15/4 whats a great high speed no-cogging motor. But lets look my 18_8 - it is exack the same as by your Bewicklungsrechner. Or not? ;-) May be you just have not thought about like that ;-) My winding Scheme is near the same - because this picture is Kabi_18_8_x. What is x? Look at two poor places for each phase (180 degerees) and look at free space on the stator ;-)
Now please await a little bid. I will add full version about Kabi_18_8 without X in half an hour.
Regards,
Herbert

It´s not necessary the se large windings to be on the outer side. I did draw it like that just for explanation. These larger wires per phase are on the places wher no wires of the same phase at all if to look Kabi_18_8_x or your winding scheme.
My final version : These "outer wires" made by "strange" style - two parts -around two+around two and wound by the same direction.
two+two=3 ;-)

WOW, talk about some advanced winding!! I can't even start to think about how you would wind that!

We're going to need a tutorial with LOTS of pics...

Good Luck!

Was my first thinking too. ;-)
Maybe a movie would show it better. Kind of 90 minutes winding horror movie.

Yes. I spent a day and then full night to wind it first time. Now I see sevaral ways to do it. Fortunately it need not much of turns - 4 was enough for me, even may be too much. But the gray hairs when at last successfully finished - its sure.
The main problem is that in five minutes you forget where you are, impossible "to look back". When its happend then need to start again. For first time it is better to wind like "x". Later you can add windings for XXL version. I used Litz wire 24x0.2mm. It has the same gross area like 1mm solid wire.
Regards,
Herbert
