Abstract :
In this paper, we introduce two kinds of magnetization type, and investigate the effect of its direction on the iron loss in brushless DC (BLDC) motor using a 2-D time-stepped voltage source finite-element method (FEM). The iron losses consist of hysteresis and eddy current loss is calculated from the time variation of the magnetic field distribution. As a result, the magnetization direction that is more advantageous in terms of the iron loss characteristic of the BLDCM is suggested.
