hi,thankyou for your response,i thought stator should be around 6/12mm thick just wanted to make sure.the bearing set up and how all moving parts attach to shaft is where im stuck.shaft will be welded to framework with furling device and yaw bearing ect on it.then i need to attatch bearings and housing onto magnet rotors and blade plate.i was going to use 4 bolt flange bearings and put them on the same side as mags,on each rotor.because the bearing and housing is about 35mm thick,when i face the magnet rotors together with bearings facing each other there will be a 55mm(at closest)air gap between magnet rotor disks,to big for my mags and stator,the magnets will be to far away to work.could i just use two housed bearings,one on rotor plate and one on magnet rotor closest to framework which means the other magnet rotor will only be joined with the threaded rod and not a bearing.this will allow magnet rotors close enough to stator to work.would this be ok?also,what do i put on the end of the shaft to stop all the moving parts falling off?i hope this is a bit clearer.im trying to work out how to do a diagram and add it to show my problem.all advice welcome
thanks
Tony
