This research deals with how to analyze flux density changes within the iron core, to predict core loss when operating 3phase permanent magnet synchronous motor by PWM sine wave. When creating sinusoidal current by PWM, large amount of harmonics is mixed in the current; which requires a significant amount of time for analysis. This research suggests a method to calculate flux density changes from each element in a short time, using non-linear FEA and linear FEA concurrently, based on 2-D magneto static FEA.
