چکیده :

This paper presents a comparison of three stator-permanent magnet (PM) motors, each with a different PM arrangement on the stator. These arrangements include tangential, radial, and tangential-radial magnetization directions of the PMs, which results in three main structures. The first and main motor structure contains two sets of PMs with tangential and radial magnetization directions, which introduces a new synthesized slot-PM flux reversal motor. The other two motors have only one PM arrangement (either tangential or radial). The simulation results under no-load and full-load conditions are carried out using finite element method, which show that the dual-PM motor structure has higher torque density and lower torque ripple compared to the other two motors. Additionally, all proposed topologies have demonstrated a robust overload capability with no significant drop in the torque-current curve.
