Abstract :
For servo drives such as permanent-magnet synchronous-machines (PMSM) the reduction of cogging-torque harmonics is of major interest. Usually the analysis of the cogging-torque harmonics is limited to studies of symmetric machines without errors, e.g. in magnetization due to manufacturing-tolerances. The novel method presented in this paper allows for fast analysis of PMSMs with asymmetric geometry and erroneous magnetization
