Permanent magnet-assisted synchronous reluctance motors (PMSynRM) have asignificantly higher average torque than synchronous reluctance motors. Thus,determining an optimal design results in a multi-material topology optimizationproblem, where one seeks to distribute ferromagnetic material, air andpermanent magnets within the rotor in an optimal manner. This study proposed anovel density-based distribution scheme, which allows for continuousmagnetization direction instead of a finite set of angles. Thus, aninterpolation scheme is established between properties pertaining to magnetsand non-linear materials. This allows for new designs to emerge withoutintroducing complex geometric parameterization or relying on the user's biasesand intuitions. Toward reducing computation time, Nitsche-type mortaring isapplied, allowing for free rotation of the rotor mesh relative to the statormesh. The average torque is approximated using only four-point staticpositions. This study investigates several interpolation schemes and presents anew one inspired by the topological derivative. We propose to filter the finaldesign for the magnetization angle using K-mean clustering accounting fortechnical feasibility constraints of magnets. Finally, the design of theelectrical motor is proposed to maximize torque value.
