This paper proposes a novel, biaxial excitation, generator for automobiles (BEGA) which has a three phase stator and a salient pole excited heteropolar rotor with multiple flux-barriers filled with low cost permanent magnets. Low voltage regulation is obtained due to the flux-barrier PM combination and, with field (excitation) low power control and a full power diode rectifier in the stator, good power/volume and superior efficiency (80 % or more) are obtained at costs comparable to those of existing Lundell generator systems. The novel system configuration, principle, performance, equations, conceptual design, finite element field analysis, performance caracteristics and preliminary tests results for a 3 kW, 9000 rpm, 42 V dc case study make the core of the paper.
