Hello hyukjin,
Here is some information.
1). Could you double check the rotation speed and frequency from scope results? to make sure if we have correct frequency.
2). What is the temperature when doing test? Does it match the magnet data?
3). How good is the magnet BH data? Is it from measurement or manufacture? Any verification? If manufacture tolerance is 10%, we could not reach 5% in the simulation.
4). For permeance coefficients, we could use field calculator to get B and H to calculate it.
