At my university, I have done a project in the past in which both the hardware (power stage, inverter..) and firmware (Field Oriented Control) were developed for a three-phase brushless motor. I have read that research is being done on the Axial Flux Motor in recent years and online I can only find the advantages it has over the Radial Flux Motor in terms of magnetic flux.

What I am asking is: from a practical point of view, is the control/drive of Axial Flux (hardware + firmware) the same of the Radial Flux? Or are there important differences to take into account when developing?

 

Based on all that I have seen relative ti the axial flux motors, what will be the biggest difference will be the voltage and current amplitudes , because of the much different form factors. Also, there might be a different number of poles, still multiples of three, of course. But because the principles of operation are the same, it is not going to be different equations, but only different numbers.
And certainly the torque versus current relations will be a bit different.

Thank you for your reply!

 

In addition the efficiency should be a bit higher, which is an intended side effect.

I think as far as efficiency is concerned there is a fairly broad argument to be made about the dissipation (elimination) of heat from the windings, But this is not very inherent to my main question.

 

Better heat dissipation is separate from increased efficiency, which would REDUCE heat generation.
