I'm a new pilot and certainly no expert on electromagnetic motors, but I had an idea that I wanted to get outside views on feasibility- probably low but worth discussing, I suppose...
What about an eletric motor-powered shaft assisted by electromagnets down the length of the shaft that assist in "pushing" the shaft...this would require a rotor mast with magnets down a certain length of the shaft to be pushed, so the weight added may nix this idea from the get-go, but if not, it seems like the electromagnets around the shaft could be adjusted to "squeeze" or release the shaft in order to adjust RPM assistance. Would it not also be possible to use the rotation of the rotor shaft to charge the batteries?? Again, not an expert on this by any means and I've heard the whole self-sustaining motor has been debunked, but it's a fascinating idea. Any thoughts?
