Study of an Improved Flux Reversal Permanent Magnet Outer-Rotor Motor

This paper analyzes two proposed flux reversal permanent magnet (FRPM) motors. The main motor, an improved FRPM (I-FRPM), was tested under no-load and full-load conditions. I-FRPM performs a higher torque density and low torque ripple structure. Using finite element methods (FEM), all curves are illustrated and compared to these two structures under fair conditions. This I-FRPM can be used in electric vehicle applications because it suggests a high torque density with minimal ripple motor structure.
