Abstract

Alternator rotor, comprising:
a set of polar wheel field windings, an exciting armature, and an electronic power supply circuit supplying power to the set of polar wheel field windings from the exciting armature,

the rotor being characterized in that the electronic power supply circuit comprises a bearing made of insulating material and conducting tracks held by said bearing, these tracks connecting the exciting conductors to terminals into which electronic components of the electronic power supply circuit are plugged and locked mechanically in place.

First claim

The invention claimed is:

1. Alternator rotor, comprising:
a set of polar wheel field windings,
an exciting armature, and
an electronic power supply circuit supplying power to the set of polar wheel field windings from the exciting armature,
wherein the electronic power supply circuit comprises a support made of insulating material and conducting tracks held by said support, these tracks connecting the exciting conductors to terminals, in the form of connectors, into which electronic components of the electronic power supply circuit are plugged and locked mechanically in place,
wherein the terminals are produced monolithically with at least a part of the conducting tracks,
wherein the conducting tracks are electrically in contact with threaded studs for the attachment of cable terminals connected to cables of the alternator, and
wherein the terminals are produced by bending the metal used to make the conducting tracks, with the said metal having been cut out from sheet.

2. Rotor according to claim 1 , the terminals constituting fast on connectors, the electronic components being provided with complementary fast on connectors.

3. Rotor according to claim 2 , the terminals constituting female fast on connectors, the electronic components being provided with complementary male fast on connectors.

4. Rotor according to claim 1 , said cables of the alternator being connected to the set of polar wheel field windings.

5. Rotor according to claim 1 , the electronic components being diode bridges.

6. Rotor according to claim 1 , the exciting armature being multiple-phased, and double-wounded, a single-phased diode bridge being associated with each phase, the diode bridges being interconnected.

7. Rotor according to claim 1 , the mechanical locking of the electronic components being performed by bolting.

8. Rotor according to claim 1 , the conducting tracks being held on the support by the overmoulding of thermoplastics material.

9. Rotor according to claim 1 , the conducting tracks being held on the support other than by overmoulding.

10. Rotor according to claim 1 , the support being positioned on an end face of the exciting armature, with the terminals projecting outwards.

11. Rotor according to claim 1 , the support being produced in the form of a base and a cover comprising openings, paths being formed in the base of the support to hold the conducting tracks.

12. Rotor according to claim 11 , ends of the conducting tracks being housed in housings in the base of the support.

13. Alternator comprising a rotor according to claim 1 .
