AI Technical Summary

Problems solved by technology

Since the input from the field armature, the output to the pole wheel and the fixing usually have to be disconnected in order to remove the diode, both known mounting and connection methods require relatively long disconnecting and removal times

Embodiment Construction

[0037] figure 1 An alternator rotor 6 according to the invention, schematically depicted in Fig. Set pole wheel magnetic field winding 4.

[0038] In the example depicted, the field armature 2 is three-phase and two-winding, but it could have a different number of phases and a different arrangement.

[0039] In the example depicted, the electronic power supply circuit 3 comprises three electronic components 3 a , 3 b , 3 c each consisting of a single-phase diode bridge comprising four diodes 10 .

[0040] Each diode bridge is associated with one phase of the field armature 2, these three bridges are as figure 1 interconnected with each other as shown in . In particular, two diodes mounted end-to-end in a bridge have a common junction connected to one terminal of a winding 31 of a phase, and the two diodes are connected at their respective - output 10b and + output 10c to a direct current (DC) bus 30a, 30b connected to the set of pole wheel field windings 4 .

Abstract

The invention relates to an alternator rotor, comprising: a pole wheel inductor winding; an exciter coating; and an electronic circuit for powering the pole wheel inductor winding from the exciter coating, the rotor being characterised in that the electronic power supply circuit comprises a substrate made of an insulating material and conductive tracks supported by said substrate, said tracks connecting the exciter conductors to terminals into which electronic components of the electronic power supply circuit are plugged and mechanically locked in place.

Description

technical field [0001] The present invention relates to alternators, and more particularly, to alternator rotors. Background technique [0002] The vast majority of known alternators used in industrial generator sets are of the "brushless" type, equipped with an electromagnetic excitation system and a main unit. Therefore, it is necessary to arrange an electronic power supply circuit, especially a rectifier, between the field armature and a set of polar wheel field windings of the main machine, so as to supply the polar wheel with direct current. [0003] Known rotating rectifiers consist of diodes in a basic housing which are of different forms connected in such a way that they form a three-phase rectifier bridge. These diodes are assembled and connected on bearings of different forms that provide electrical insulation with respect to the metal block of the alternator and continuity from the windings of the field armature to the windings of the pole wheels. [0004] Const...
