Dual Mechanical Port Machine with Interior PM Outer-Rotor for Hybrid Electric Vehicles

The dual mechanical port machine is a special machine which has dual output to connect engine and wheel in hybrid electric vehicles. This paper presents a new dual mechanical port machine for hybrid electric vehicle drives. An interior PM rotor structure was proposed to enhance the reluctance torque contribution and flux weakening capability. The principle of operation, system configuration, and control issues are illustrated firstly. Design and analysis of interior PM outer-rotor were discussed as well. Finally, the advanced finite element method was employed to calculate and verify the electromagnetic performance of proposed dual mechanical port machine with interior PM outer-rotor.
