stator coils,
hi everyone, by the hologram effect I simply mean that most of the sellers draw you a picture of what you would like to here but that isn't what there selling you. even the parts are hyped up way beyond there ability . ill give my opinions one blog at a time. making your own mill is a good feeling, each piece you choose will effect its outcome . lets start with the STATOR COILS. these are my own opinions and im no expert but I know what works because I did it or made it and tested it, iv got a lot of scrap to prove it too. so here we go, the shapes will effect the way the coils relate with the magnets, also how much copper will see usable flux, even the copper that dosnt see usable flux when more than needed will be carrying eddie currents witch is one of the biggest problems with power generation, and simply we have to live with, they can be minimised with design. I think the circle shape is close to useless , it uses the least flux and at steep angles, the magnets almost never relate perfectly to the coil and will cause power to stall in the coils every time one crosses a coil. the pie shaped one are headed in the right direction but I find there to short on one end and to long on the other causing the magnet relation problems again. the LONG oval seems to work , the current numbers iv seen the highest were from long ovals and they were compaired to the same size wire and turns. I wouldn't believe it until I seen the numbers but that is why we need to test, test, test. I felt the numbers of 2.5 to 4.8v and the highest at 1.3 amp per coil tested by each coil seperatly at the same test conditions were still to low. I know these unit produced 7 to 10000w after assembly but there is so much coil still not being used, I also felt the coil thickness was lacking. with the magnets today there is a lot of room to expand with there magnetic ability, the flux is in most all directions around the magnet but we all only use one of the poles and try to get as close as possible to the coils, I don't think the full picture is being used on this aspect. if you have to cut the flux at 90 deg and the magnet is laying flat on top say 2mm above, the only difference I see that can be made different than all the other coils iv seen is the direction of the wire winding . if the wire traveled from top on the left to the bottom on the left then across to the bottom on the left and again to the top on the left being one wrap around the coil to a count of the same you would use on any other type of coil you used before this would have 100% flux saturation on evry pass of the magnet and the current flow through the coil would always be in the same direction for any point of the magnets travel across the coil with no stall points to lower power production.this would drasticly help with the eddie currents also. the width of the coil should be slightly wider than the magnet, I find 1/4" on each side of a 2" magnet and the coil length 1/2 longer on each end will show numbers not thought possible from such a small coil. I will warn of the fact that the coils will produce more power than your able to cool if you push them hard at high rpm, { 330 rpm } im testing with a 36" magnet circle dia and 33 coil with 1/8" between coil ends. thanks for reading and I HOPE this is food for thought.
