I was wondering if there has been any testing of a multiple stator and rotor Axial Flux machine. Basicly just double stacking so you would have a rotor then a...

Multiple rotor/stators works to keep diameter down but a more efficient use of your magnets is to keep to two rotors and one stator. Let the diameter increase...

It would be a poor use of your magnet and copper dollar. For example, if you doubled up with 2 stators, twice the magnets, and 3 magnet rotors, you'd get twice...

Unfortunatly you would get a net loss due to inefficiency of the motor and generator. The axial flux generator is more efficient than tradiditional generators...

Yes you will add additional load to the 25hp motor. Figure whatever load you are powering with the axial flux, plus 30% that should cover it. Why not use the...
