摘要： The synchronous electrical machine (8) comprises a stator (9) and a wounded rotor (10), the stator comprising a plurality of phases, each phase comprising coils (13) connected together and magnetic stator poles cores (12) fixed on a stator frame (11) and evenly distributed along a stator diameter, each coil being wounded around a different magnetic stator pole core to form a magnetic stator pole, each phase comprising a same number of magnetic stator poles, the magnetic stator poles of each phase being disposed in the stator frame to form a concentric winding stator.
The rotor (10) comprises a plurality of magnetic rotor pole cores (14) evenly distributed around the rotor (10) and rotor coils (14), each rotor coil being wounded around a different magnetic rotor pole core to form a magnetic rotor pole.

摘要： A synchronous machine and related systems include a stator and rotor separated by an air gap. The rotor includes a rotating DC power supply coupled to exciter windings disposed adjacent the air gap. Power from air gap harmonics, including air gap slot harmonics induce current in the exciter windings, which is rectified and supplied to the rotor field windings. In operation, a desired current level in the rotor field windings can be achieved through control of the DC power supply or superposition of harmonics into the stator winding current which induces the prescribed current in exciter windings.

摘要： The present invention provides an automotive alternator that can reduce axial dimensions of a rectifying apparatus while suppressing reductions in reliability of rectifying elements and cooling of the alternator.
In this rectifying apparatus, a circuit board is disposed between a first rectifying element holding portion and a second rectifying element holding portion such that first rectifying element connecting portions are disposed in a loosely fitted state inside a second penetrating aperture that is formed on the second rectifying element holding portion, and second rectifying element connecting portions are disposed in a loosely fitted state inside a first penetrating aperture that is formed on the first rectifying element holding portion; first leading electrodes of a plurality of first rectifying elements respectively extend axially and are connected to each of the first rectifying element connecting portions; and second leading electrodes of a plurality of second rectifying elements respectively extend axially and are connected to each of the second rectifying element connecting portions.
