No worries Mac, you are allowed to get old. Good info though for somebody who don't know. Thanks Pete. I don't need to say any more.
But sombody may want to know. The magnets are N50M, 50mm round x 12mm thick. Coils are 48mm ID and the OD is about 72-74mm. The coils have 100 turns of 1.25mm2 wire. Coils are equaly spaced as are the magnets equaly spaced. The centre of the magnets and coils is a diameter of 246mm. And yes,the 3:4 ratio is the critical bit.
Temporary fit the stator to check where to run the wires out and then finish this off.
Assembled the AXFX unit and discovered I did need the spacer I made after all, so pulled apart and put in the spacer and machined the front of the rotor hub so the blades would still go on. The jacking bolts are 200mm long and there was no significant magnetic pull at that distance apart. Any how here is a few pictures.
Preliminary spin and yes voltage does occur. Details later after I test properly.
