This paper presents a comparison of different permanent magnet arrangement of brushless DC motor. Firstly, design and principal equations of these motors are provided. Five common permanent magnet arrangements are considered. Best arrangement is selected in terms of performance characteristics such as efficiency, output torque, weight of motor and PMs and etc. based on simulation with finite element analysis. Simulation is conducted by 2-D finite element analysis software
