Numerical Comparison of Different Electric Motors (IM and PM) effects on a Hybrid Electric Vehicle

Abstract

The motor / generator instrument, which is the one of the key important components of hybrid electric vehicles, influence vehicleefficiency and emission scale with its types and features. For that reason, the electric motor (electric machine-EM) selection andidentification are playing a crucial role. In this simulation study, effects of two different motors, Induction and Permanent Magnet (IMand PM) to emission and performance were compared for two driving cycles (FTP75 and NEDC) on a serial configuration hybridelectric vehicle which modeled with AVL Cruise. The general purpose of the work is, selecting electric motors that they have sameoutput powers although the rotational speeds are different; and modeled for the same vehicle and identifing the effects of differentdriving cycles on the vehicles were compared. HEVs performance and emission results illustrated and electric machines performancesand efficiency maps are graphically charted. Overall performance and emission outputs for two different driving cycles are discusseddetailed. Also, a general concluded summary table that related the performance and emission outputs of different machines usage ispresented. As a result, according to these modeling and test results, PM motor is more efficient than IM motor on overall simulationresults, especially decreases the emission values at high speeds
