Constrained optimization of the brushless DC motor using the salp swarm algorithm

: This paper presents an algorithm and optimization procedure for the optimization of the outer rotor structure of the brushless DC (BLDC) motor. The optimization software wasdevelopedintheDelphiTiburóndevelopmentenvironment.Theoptimizationprocedure is based on the salp swarm algorithm. The effectiveness of the developed optimization procedure wascompared withgenetic algorithmand particleswarm optimizationalgorithm. The mathematical model of the device includes the electromagnetic field equations taking into account the non-linearity of the ferromagnetic material, equations of external supply circuits and equations of mechanical motion. The external penalty function was introduced into the optimization algorithm to take into account the non-linear constraint function.
