A New Electromechanical Concept for Hybrid Powertrains

摘要

This paper is devoted to a finite-element-analysis-based design of an electromagnetic set dedicated to hybrid propulsion systems. It consists of two concentric permanent magnet machines, yielding the so-called "single stator dual rotor permanent magnet machine", with an inner rotor, an outer rotor and a stator sandwiched between the two rotors. In order to decouple magnetically both machines, a nonmagnetic material ring is inserted in between the two stators. Given the small dimensions of the inner machine, special attention is focused upon its sizing.
