This paper presents a comparison of two inlet permanent magnet synchronous machines with concentrated windings. A novel 24-teeth/28-poles machine design with flux barriers in the stator teeth is compared to a common 30-teeth/20-poles design, which is widely used for hybrid electric vehicle (HEV) applications. Detailed comparison of important machine characteristics such as torque ripple, iron losses, eddy current losses in the magnets, axial length and machine weight is presented. According to the study, the novel 24-teeth/28-poles machine design offers a high saving potential concerning the space requirement and production costs. At the same time this machine topology generates a smoother torque compared to the 30-teeth/20-poles topology.
