Comparative Study and Design Optimization of a Dual-Mechanical-Port Electric Machine for Hybrid Electric Vehicle Applications

A new dual-mechanical-port (DMP) electric machine for hybrid vehicle applications, particularly in the power-split continuously variable transmission systems, is proposed this paper. In order to comprehensively and quantitatively evaluate pros cons of machine, a comparative study four DMP machines with different topologies conducted. These investigated include conventional spoke-type permanent magnets, reluctance rotor, open slots which Even though these have similar topologies, they operating principles, are demonstrated detail. The comparison results indicate that outperforms others terms torque/power density, efficiency, magnet utilization, etc. Accordingly, selected further investigation optimization. large-scale multi-objective optimization carried out where differential evolution algorithm serves as global search engine target optimal performance. Finally, an design prototyped, experimental performed verify effectiveness analysis simulation
