Magnetic flux pattern and magnetization curve of Exterior Rotor Permanent Magnet Brushless DC (ERPMBLDC) Motor are obtained using an advanced numerical method called Finite Element Method. This method better suits to deal with the complicated internal structure of the machine and non linear magnetic characteristics. Finite Element method Magnetics (FEMM) software Version 4.2 is used to simulate two dimensional structure of the machine. The results are plotted to produce flux and torque patterns in the ERPMBLDC domain. Various positions of the rotor under a complete cycle of excitation of the stator is analyzed to enhance the torque developed by the Motor.
