This research study was conducted in an effort to understand what effects the rotor configuration has on the performance of a permanent magnet synchronous machine, independent of the stator configuration. Three motors were designed with different interior permanent magnet rotor configurations with the same stator laminations and were analyzed using a combination FEA dq -axis circuit model. The results show that the performance characteristics affected by the rotor configuration were synchronous and reluctance torque production, torque ripple, efficiency and parameter variation. The V-shaped rotor configuration produced the most torque at 70 Nm. The Flat rotor configuration had the second highest torque production at 67 Nm. The Radial rotor configuration had the highest efficiency but had the highest torque ripple. The parameter variation had an effect on the reluctance torque production capabilities of each rotor configuration due to the saturation in the machines.
