Electromagnetic Analysis of Permanent Magnet Brushed Direct Current Motors for Automotive Applications—Part 2

This paper describes the modelling and electromagnetic analysis of Permanent Magnet Brushed Direct Current (PMBDC) motor using Finite Element Analysis (FEA) software packages. The designed motors referred in this analysis are fit for use in applications of the electronic throttle control and exhaust gas recirculation in automobiles. Performances of the designed PMBDC models are compared with the traditionally used machines. Three PMBDC models with different operating characteristics are proposed for the two applications. Each model is suitable for use in both applications. Cost analysis of the motors is also carried out, and comparison with the traditionally used machines is done.
