Hello, it has been a while. My motor conversion is still flying going on a couple of years.
Any way I took on making a dual rotor but have been working at it slowly, all by hand and hand tools. I have finished my 9 coils and after comparison I would like comments on whether I need to tighten up on the sizes.
The coils are made of #14 wire and wound 80 turns (suppose to be)
After they were done I weighed then in grams and got as high as 367g and low as 274g this works out to be 15ft more wire on the largest to the smallest (1ft wire = 5.9 grams). 7 of the 9 coils are within 4 ft total length of each other.
The question, is this difference in length acceptable and if so, how would I orient the coils to cancel out any possible vibration caused by the different lengths?
Next time I think I will slightly over wind each coil and then remove the proportionate amount of wire from each.
