Analysis of End-Effect Torque and Multi-Objective Optimization for Multi-Port Spatial Permanent Magnet Synchronous Motor

Multi-objective Hierarchical Optimization of Interior Permanent Magnet Synchronous Machines Based on Rotor Surface Modification

“…Then, the comprehensive optimization objective function is used to evaluate the motor torque performance, and the weight coefficient λ is used to represent the relative importance of the optimization objective. There is no fixed standard for determining the weight coefficient, which is usually chosen by experience [19]. The sum of the weight coefficients is 1, λ1=λ2=0.5 is taken to give consideration to the output torque and torque ripple.…”

“…In reference [18], a method combining RSM and seagull optimization algorithm was used for multi-objective optimization of the interior motor. In reference [19], a method combining parametric hierarchical design and RSM was proposed for multi-objective optimization of the interior motor with asymmetric V-rotor structure. However, the parameters selected in references [18][19] are only limited to the rotor.…”
