This study explores the advantages of a dual axial flux permanent magnet synchronous machine (AFPMSM) structure compared with a single AFPMSM, addressing the increasing demand for devices with high torque and compact dimensions for a left ventricular assist device (LVAD) pump. The AFPMSM design offers superior torque and power densities, making it a potential solution to the challenges posed by the need for compact yet powerful electric machines. The investigation involves the comparison of efficiency, torque ripple, and thermal losses between a dual-motor AFPMSM configuration and a single-motor setup. Key findings include a significant reduction in torque ripple, from 22% to 12.6%, achieved by assembling dual AFPMSMs at different angles. The dual-motor system also demonstrates the ability to maintain a high efficiency of approximately 60% through optimal load sharing, even at high loads. Thermal analysis revealed substantial temperature reductions, making the dual AFPMSM structure particularly advantageous, especially for small-scale applications. Overall, this research highlights the multifaceted benefits of employing a dual AFPMSM structure in addressing the complexities of high torque and small size requirements in electric machine design.
