Abstract: The paper is devoted to a finite element analysis based design of an
electromagnetic system dedicated for 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 non magnetic material ring is inserted between
the two stators. Giving the small dimensions of the inner machine, special
attention is focused upon its sizing.
Keywords: single stator dual rotor permanent magnet machine, magnetic decoupling, torque production capability
