Hi all, This is my first attemp to try winding. I have 3 different fan waiting for restoration. I started one of the younger one :) 1960 Russian fan. Unfortunately strator windings has been fried :). I tear down all the parts. I tried to figure out direction and turns of one side. 2 of them was much better. I measure length of wire and its 88 m for one side and I separate turns in 20 groups.And 580 turns total. I measured diameter with my caliper and it was 0.28 mm. I couldn't find in that diameter. I decided to use 0.30. Firstly I wound 2 x CCW and 2 CW direction. With this winding all wires and strator get hot extremely. Than I flip over CCW ones and connect according to which I found a schematics on internet Here are some photos old windings and new one and also simple winding device I made from old cordless drill. Thanks       with this connection all wires was hot. I rotate CCW ones 180 degree and connect as schematics shown. Now rotor is spinning well. It's not hot. next step is one of plastic gear is damaged I will draw in cad and print from 3d printer. Also brass bushings are bit loose. I will make new ones on my lathe.

Nice! Can you make different kinds of gears in CAD if we had the specs? I'd love to be able to 3d print a gear I need but I don't have the CAD skills to design it

Hi Jeff Thanks Of course you can make any gear or any parts with 3d printer. Design and drawing takes some time. But if you use fusion 360 it's quite easy. check some useful tutorial in youtube Below "south pointing chariot" parts and gears are printed in 3d printer by me.

Hi, I drew damaged gear on cad according to measurements. After that I print it from 3d printer. I attached original psition works well.

That is awesome! I'll have to give fusion 360 a look. Do you mainly need the measurements and it'll draw the gear? Or do you have to actually hand draw it out with the mouse?

Hi Jeff Gear size does matter. Therefore you need exact measurements from old one. You may see at first photo. I measure inner, outer diameter, lenght etc with caliper. After that I draw on Fusion. At the moment I generate a new gear set for Siemens fan. But now all the gears are missing in the gearbox. I have to figureout gear ratio and diameter Good luck
