    • A brushless three-phase synchronous generator includes a stator having primary generating windings and stator excitation windings whose number of poles is odd-number times the number of poles of the primary generating windings. The generator further includes a cylindrical rotor on which a plurality of field windings are wound in a full-pitch concentrated winding form. The plurality of field windings are respectively short-circuited by the corresponding diodes. A plurality of field windings in which voltages of the same phase are induced based on the odd-order spatial higher harmonic magnetic fields are connected in parallel and further connected in parallel to the central field windings which effectively produce primary field magnetic fluxes. A circulating rectifier element is connected in parallel to the central field windings. Improvement in the waveforms of the primary magnetic fields can be achieved and self-excitation in the case where the single-phase loads are connected can be prevented from occurring while magnetic coupling of the rotor field windings to the spatial higher harmonic components of the armature reaction magnetic fields is effectively maintained well.
