This paper presents a theoretical analysis of developed DC permanent magnet brushless motor. This motor has three phase cylindrical stator windings and two salient poles permanent magnet rotor. The motor construction, equivalent circuit, analysis and motor characteristics are given. The motor has a high value of the ripple factor. This problem may be overcome by improving the excitation method. The switching ON time of excitation for each phase can be advanced. The motor torque behavior is improved with increasing this advanced time (angle). The optimum angle is 40○ for phase advancing. The results show the increasing and continuity of the output torque with minimum ripple factor. This leads to increasing of the developed torque for the same motor dimensions.
