This paper proposes a new brushless double mechanical port flux-switching permanent magnet (BDMP-FSPM) motor for plug-in hybrid electric vehicles applications. The key is to highly integrate two rotors and single stator into one motor frame, which is based on the concept of incorporating the double-rotor motor into a stator-permanent-magnet motor. In addition, by combining the non-contact magnetic planetary gear with the proposed motor, the new resulting electric continuous variable transmission system can not only realize the required speed and torque transmission, but also manage the power split and combination in various driving cycles. The electromagnetic performances of the proposed motor are analyzed by using the finite-element method, such as magnetic field distribution, coupled back-EMF, torque performances, torque-speed curves, and power-speed curves. Experimental results of the BDMP-FSPM prototype are also given to verify the validity.
