Hello,
Is there any chance of "tunning" the rotor plate (axial flux generator) as to concentrate the magnetic fieldlines in the area of interest (coil legs)?
I've seen some comercial rotor plates as in the image bellow (all rights belongs to solbergavind owner):
As you can see in this picture, there is a hole between each magnet. I know that those holes are for ventilation/low mass purpose mainly but they could also break the magnetic fieldlines path on the end-of-coils area (the bottom of each stator coil).
On top of the rotor plate I can see a similar solution (between each magnet) - to redirect the magnetic field only through coil legs.
Am I getting nuts or there are some scientific facts?!
PS: I have the possibility to CNC laser cut the rotor plates so I could ask for any profile I want.
