Performance of permanent magnet synchronous machines based on different winding arrangements and magnetization patterns

This paper investigates the performance of surface-mounted permanent magnet synchronous motors (PMSMs) with two distinct winding configurations and three magnetization patterns. The winding arrangements studied include a 9-slot/10-pole PMSM with single-tooth wound coils and a 15-slot/4-pole PMSM with distributed windings. Both motor designs feature surface-mounted permanent magnets (PMs) on the rotor, with magnetization patterns configured as parallel, radial, and segmented Halbach respectively. PMSMs are widely used in applications such as electric vehicles and renewable energy systems, where high efficiency and performance are critical. This research examines the sensitivity of motor performance to winding configurations and magnetization patterns through finite element simulations in ANSYS Maxwell 2D. Key performance metrics analyzed include airgap flux density, phase back-EMF, cogging torque, and motor output torque. The findings highlight how these design variations influence motor efficiency, average torque, and torque ripple. By comparing the strengths and weaknesses of each configuration, the study identifies optimal combinations of windings and magnetization patterns for specific applications. The results offer valuable insights into PMSM design, aiding in the development of more efficient and reliable motors. This research contributes to informed decision-making in motor design and manufacturing processes, supporting the advancement of modern industrial and energy applications.
