The Optimization of the Interior Permanent Magnetic Motor Case Study

This paper presents two optimization methods of an interior permanent magnetic motor (IPM). The first method is based on the non-dominated sorting genetic algorithm II (NSGA-II), while second one NSGA-III algorithm. focus reduction cogging torque (CT), which acts upon rotor when IPM not powered, and current that flows through three windings 0. influence CT over operation a negative one, inducing vibrations are desired. limitation these influences desired way for improvement. optimizations applied entailed change geometrical configuration stator whilst maintaining exterior dimensions unaltered. Through this simple but robust approach, performance proposed was improved.
