dc.description.resumoPermanent magnet synchronous motors with spatial harmonics can develop significant torque ripple under sinusoidal stator current feeding strategy. Usual approaches to reduce torque ripple aim the design of stator current harmonics, based on the machine electrical parameters, to induce compensating torque pulsations. However, the machine parameters are highly dependent on the electric load and the current harmonic content. Thus, these dependencies impose a challenge on the search for optimum stator currents. To overcome this drawback, this paper presents a genetic algorithm (GA) optimum current search procedure based on the machine design assisted by the Finite Element Method (FEM). Additionally, the variation of the onload estimated electrical parameters is analyzed considering different current feeding strategies. The results demonstrate that, according to FEM analysis, a null torque ripple with an increased torque per Ampère ratio is achieved and the parameter analysis demonstrates their different variation according to the current strategy. https://doi.org/10.53316/sepoc2021.026por

  • Proceedings of the 13th Seminar on Power Electronics and Control (SEPOC 2021) [82]
    The Seminar on Power Electronics and Control (SEPOC) is an international conference technically co-sponsored by IEEE-IAS.

    SEPOC 2021 was held online from May 15 to 18, 2021, organized by the IEEE Student Branch and Professional Joint Chapter from the Federal University of Santa Maria (UFSM), the National Institute of Science and Technology on Distributed Generation (INCT-GD), the Graduate Program in Electrical Engineering (PPGEE-UFSM) and the Technology Center (CT/UFSM).
    The objective of the seminar was to provide interaction between academia and industry to discuss the latest cutting-edge technologies on Power Electronics and Control and their applications. The SEPOC 2021 theme was "Photovoltaic Energy and The Consolidation of Distributed Generation".
