This paper presents the d-q model, operational direct and quadrature axis inductances by means of locked-rotor tests, together with other characteristics for a 3 kW, 9000 rpm, 42 V d c. prototype of biaxial excitation generator for automobiles (BEGA). Despite the good power/volume ratio and low costs but due of their low efficiency, the actual exclusively used automotive alternators, the claw-poles generators, will be replaced in the near future by new types of electrical generators which has to generate more power by keeping the approximately the same volume as before. In order, new improvements were made by inserting PM's in various ways or by changing the number of poles but those solutions has not solved the efficiency problems and neither system dynamic behave for consumer voltage recovery. The biaxial excitation generator for automobiles (BEGA) has a three-phase stator and a salient pole excited heteropolar rotor with multiple flux-barriers filled with low cost permanent magnets. Its configuration, operation principle, d-q model equations operational parameters and some promising performance characteristics results consitute the core of the paper.
