If all things are the same in an axial flux motor, (winding shapes, diameter, length, etc.)
How predictable is the difference between Iron core, air core, and soft ferrite cores performance.
I have been told silicon steel core would provide better continuous torque with a lower max rpm, efficiency reduction, and increased cogging torque.
Air core would be the most efficient with lower torque, higher rpm and almost no cogging.
And ferrite would be the worst as it would saturate and still have cogging with lower rpm.
Everything else being the same is there a general percentage difference between iron core and air core?
Tnx
