Time-Periodic Motor Modeling
The traditional electromagnetic transient modeling approach has been covered in the previous parts of this course. In this part, we will cover the time-periodic approach for electric motors. Where the transient approach uses the previous solution to calculate the next solution, the time-periodic approach uses the principle that the result is the same at time = 0 and at each full electrical period. This approach is particularly useful when modeling nonlinear problems and nonlinear materials to complete parameter studies, efficiency, and temperature maps. Watch the video below to learn more and see a demonstration.
