This paper proposes a new magnetic-planetary-geared permanent magnet brushless (MPG-PMBL) machine for hybrid electric vehicles . The key is to integrate a magnetic planetary gear into permanent magnet brushless machine. Thus, the resulting machine can achieve both power split and mixing flexibly, and therefore, can obtain ultralow emission and high fuel efficiency at different operational modes. Moreover, by incorporating the concept of non-contact transmission mechanisms of magnetic gear, the proposed machine possesses the merits of small size, light weight, reliability, reduced maintenance and inherent overload protection. The machine topology and operation principle are presented. By using the finite element method, the electromagnetic performances are analyzed. Finally, multi-operational modes, efficiency and loss of the machine are simulated to evaluate the proposed system.
