A novel African buffalo optimization for the minimization of cogging torque in modified permanent magnet DC motor

Abstract

Nowadays, various approaches have been presented to minimize the cogging torque in permanent magnet DC motors. However, tentatively entire approaches are rather incapable of reducing the cogging torque and this can cause a variety of problems. A large quantity of electric energy is formed in a PMDC motor concurrently, the majority of the energy exhausted because these motors are not operated at full load. Therefore, in this paper, a novel African Buffalo Optimization (ABO) based cogging torque reduction technique is proposed in modified PMDC motor. Moreover, this paper includes the mathematical-modeling design of the proposed approach to optimize the design of modified PMDC Motor. The proposed technique is implemented in Infolytica MotorSolve Software v4.1. Consequently, the Signal to Noise Ratio (SNR) of a modified PMDC motor can be improved by this proposed ABO technique. The simulation outcomes of the proposed technique are compared with dissimilar existing techniques in terms of cogging torque, flux density, armature speed, net magnetomotive force, and so on. Thus, the comparison shows that the proposed method is significantly improved the performance of a modified PMDC motor while compared with the other methods.
