| Resumo: |
This work investigates the different strategies of on-load cogging torque calculation in permanent magnet synchronous machine (PMSM) with the aid of the Finite Element Method along with the Frozen Permeability Method. Numerous researches have been carried throughout the years in order to accomplish the task of segregating the torque components and figure out the origins of torque oscillations. However, most of them have failed as they usually attribute the torque ripple only to the cogging torque and taking general conclusions based only in one type of PMSM. Here, in the present text, the investigation is carried out comparing the most cited and recent methods of on-load cogging torque assessment taking into account the electromagnetic saturation in different PMSM topologies. The results and discussion show that the most suitable methodology is not based on electromagnetic energy neither based on the electromagnetic coenergy but based on flux distribution. |
