What is it about?
We have shown that the torque ripple of an axial flux induction motor can be reduced using dual-rotor structure and properly setting the relative position of two rotor disks. Also, we have introduced an algorithm based on finite element method to calculate the rotor rotors displacement while motor assembling. The results are compared with various possible skewing arrangements of dual-rotor disks, in terms of torque and loss characteristics.

Why is it important?
It is shown that the skewing of the rotor slots can be avoided using the new concept, which is named shifted rotors technique, which results in easier manufacturing, more produced torque and better power factor. The Also, shifted rotors technique, will ensure less iron losses compared to the skewed rotors, while its joule loss is larger because of more current harmonics in the rotor.
Perspectives
I hope this article be interesting for the researchers, who work in the field of electrical machines design since I believe that it introduces a novel method for design of induction motors.
