Accurate assessment of the electro-magneto-mechanical energy conversion process usually requires a multi-physics Finite Element (FEA) analysis. Since FE analysis is a time consuming numerical process, lumped parameter models, simplified equivalent magnetic circuits, and separated field analysis are usually used for design and control of electric motor and generator drives. This computational burden...
The design optimization of IPM motors for wide speed ranges is considered in this paper by means of a FEA-based multi-objective genetic algorithm (MOGA). The minimum number of simulations is pursued for the fast evaluation of four goal functions: maximum torque, minimum torque ripple, maximum flux weakening capability and minimum rotor harmonic losses. The paper is focused on the rotor design, that...
