Emerging advanced permanent-magnet brushless machines for hybrid vehicles

In this chapter, three emerging advanced permanent-magnet brushless machines are presented for hybrid vehicles. By introducing different types of hybrid vehicles, the power management for these vehicles is briefly introduced. Then, based on the aforementioned hybrid vehicle types, three emerging machines are presented for application in these vehicles, namely an outer-rotor permanent-magnet vernier motor for electric vehicle in-wheel motor drive, a dual-rotor dual-stator magnetic-geared PM machine for power splitting in series-parallel-type vehicles, and a hybrid stator-PM machine using as an integrated-starter-generator for complex-hybrid-type vehicles. The design equations, operating principle and analytical results of these machines are quantitatively elaborated and discussed.
