Preliminary Electromagnetic Design Expert System for Surface-Mounted Permanent Magnet Brushless Machine

Abstract:

An accurate and fast flowchart of surface-mounted permanent magnet brushless machine (SPMBM) design based on exact analytical method (EAM) rivaling finite element method (FEM) is formally proposed in this paper. It is recognized as a promising expert system for the preliminary electromagnetic design of SPMBM, even to replace the conventional design flowchart using equivalent magnetic circuit method (EMCM). By applying this expert system aiming at the low cogging torque and high power density, a special SPMBM named electronically commutated permanent magnet synchronous DC machine (PMSDCM) with conventional DC armature winding is put forward and verified based on both the simulation and experiment.
