Periodic boundary condition for 3-D magnetic field analysis and its applications to electrical machines

A periodic boundary condition in 3-D analysis is examined. The definition of 3-D periodic phenomena is clarified, and the periodic conditions for the A- phi boundary conditions are shown by analyzing some models and observing that the CPU time is considerably decreased. The periodic condition is app...

Zusammenfassung:A periodic boundary condition in 3-D analysis is examined. The definition of 3-D periodic phenomena is clarified, and the periodic conditions for the A- phi boundary conditions are shown by analyzing some models and observing that the CPU time is considerably decreased. The periodic condition is applied to the analysis of an actual induction motor.< >
