Abstract

We present a new integrated electromechanical set for automotive hybrid propulsion systems. It consists of two concentric permanent-magnet (PM) machines with inner and outer surface-mounted PM rotors, and a stator sandwiched between the two rotors, yielding a so-called ldquosingle-stator dual-rotor PM machinerdquo. The stator magnetic circuit consists of two concentric parts decoupled by a nonmagnetic ring. In an earlier topology, distributed windings were used in both stators. We substitute concentrated windings to extend the flux weakening range. We discuss our investigation of the magnetomotive force (MMF) spatial profile and of the torque production capability of this dedicated concentrated winding surface-mounted PM machine.
