The proposed transformation, called dqy, enables the utilization of all harmonic components present in the back electromotive force for electromagnetic torque production. The proposed extension is applied to a permanent magnet synchronous machine through a magnitude amplification coefficient and a rotation angle. The new coordinate system allows for the reduction of power losses in the stator winding, as all current flowing through the machine contributes to the production of electromagnetic torque. The results obtained through simulation and experimental testing validate the effectiveness of the proposed vector control.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Máquina síncrona de imãs permanentesControle vetorialForça contra eletromotriz não senoidalComponente de sequência zeroPermanent magnet synchronous machineVector controlNon-sinusoidal back electromotive forceZero-sequence component.CIENCIAS EXATAS E DA TERRA::CIENCIA DA COMPUTACAO::TEORIA DA COMPUTACAOTese
