We call our machines Multi Rotor since the number of rotors are no longer limited from one to three rotors. Our prototype is 5 rotors and under 5 inches in diameter.
The advantage of our patent pending design is we can reduce rotor size which allows us to develop machines with higher RPM's then conventional axial flux machines.
By adding rotors we capture the torque that would normally be lost by reducing the diameter of the rotor. Axial flux motors make more power by moving the rotor to stator magnetic interface away from the central axis.
This means a 9 inch Axial flux motors have a huge leverage advantage over the conventional radial flux motors because that magnetic interface (or interaction zone) is between 6 and 8 inches away from the central shaft. Radial flux motors of the same outside diameter have the interaction zone anywhere from 2-4 inches from the central axis.
Think of the difference as a 4 inch lever and an 8 inch pry bar!.
