If you have the same number of magnets as coils, the motor will not work. You want a 9N12P Motor: http://www.bavaria-direct.co.za/scheme/common/ Winding Scheme Calculator: http://www.bavaria-direct.co.za/scheme/calculator/ This will work too if the coils are on the outside and the magnets inside.

My dad was with a B-29 squadron in WWII. --- End quote --- :( The Super Constellations and the B-29s were both magnificent aircraft, it's a shame that so few of them are still flying. --- End quote --- When you start adding up all the pistons, cams, valves and on and on and on, it's not hard to imagine why they are gone. Just the regular maintenance would keep a small city busy. |

I was on a SC and it pitched up and down. Can you guess how this was done? Very funny. |

This really looks like a basic brushless motor developing. Writing a PIC program for the ESC (electronic speed control) is a great way to become familar with writing code and programing. |

I do not know why, but I made a rotor with 10 magnets. The plan was to saturate in superglue and wrap with the yellow thread, them machine down the excess aluminum, glue and thread. Maybe I'll need to start over with 12 magnets, or just make 7 coils? I still don't know how large to make the coils and turns, and wire gauge, but I'll probably just use what I have... That was the second one I made because the first was perfect, but for 12 magnets. I thought I was making it for 10 and whittled it down some and then the slot was too large. :( |
