Abstract:2D whole field finite element method(FEM)based on Ansoft software was adapted,and the magnetic field distribution of permanent-magnet brushless DC motor(BLDC)were calculated.The above discussion can provide reliable theory foundation for the reasonable establishment of nonlinear model BLDCM and the further exploitation and application.
