Reluctance motor with strong rotor anisotropy

A new rotor design is presented for the synchronous reluctance motor. It has something in common with the segmented and axially laminated rotors which have been developed in the past. The new rotor achieves strong anisotropy by interleaving magnetic iron laminations with nonmagnetic spacers of approximately equal thickness. It is shown that the magnetizing inductance is much lower in the quadrature than the direct axis and that this rotor has the potential to develop more torque than earlier machines. Laboratory results are presented, and the machine is compared to an induction motor in the same frame.<>
