Abstract |
In this paper, the calculation torque using the d-q axis has advantage like faster execution time. However, the torque ripple can't be considered in the torque calculation using d-q axis equivalent circuit because the time-dependent component is removed. When d-q transformation was performed, it was founded that some parameters has some characteristics. These characteristics were considered for representing torque ripple. The calculation with d-q axis transformation and Finite Element Analysis(FEA) were performed, and the results were compared. As a result, it was validated that the calculated torque can be expressed with ripple. |
