Abstract :
Interior permanent magnet motors are widely used in various fields. However, in high-speed operations, it is important to decrease the eddy current loss in the permanent magnet. Therefore, we propose to divide the permanent magnet. This paper describes a practical technique to analyze the eddy current in the divided magnet. The effect of division of permanent magnet on eddy current loss is also quantitatively clarified
