A permanent magnet dual mechanical port machine (DMPM) is a compact and pure electrical solution to the hybrid electric vehicle traction, which features as two independent rotors and permanent magnets mounted on the outer rotor. The key barrier prevent the DMPM from practical usage is the existence of the brush and slipring. A way to eliminate the brush and slipring is presented in this paper, which...
According to the torque-speed characteristic of permanent magnet double-rotor machine, the loss has been analyzed. Combining with structure and distribution of heat source of the machine and its cooling system, a lumped parameter thermal model has been formed to simulate analysis and verify thermal design for the adjustment of key design variables.
