Performance analysis of a permanet magnet SMC transverse flux motor with multiobjective optimization strategy

This paper presents the performance analysis of two different multiobjective optimization schemes for a permanent magnet transverse flux motor (TFM) drive, in which soft magnetic composite (SMC) material is employed as the motor core. Firstly, deterministic multiobjective optimization method is introduced for developing the SMC TFM motor drive while taking into account the unique properties of SMC. Secondly, robust multiobjective optimization method is presented to improve the reliability of the drive from the point of view of industrial application. The optimization results show that the performances of the drive system with robust design optimization have improved a lot compared with deterministic design optimization; the designed products have very low probability of failure against manufacturing error and environment variation; this is crucial in modern quality control. Furthermore, the users have flexibility to choose among a series of optimal results in those obtained multiobjective optimization solutions.
