A rotor () for a rotary electric machine which comprises: two field spiders () each of which runs more or less radially with respect to the main axis of the rotor () and comprises a series of axial arms () in which each arm () runs axially inwards from the associated field spider (), towards the other field spider () in such a way that each arm () of a field spider () lies in the space there is between two consecutive arms () of the other field spider (); and at least one magnetic element () the main orientation of which is longitudinal position transversely between two adjacent arms () belonging one to each field spider () and which comprises at least one magnet (), characterized in that the magnetic element () comprises at least one support shim () made of a non-magnetic material and mounted on a transverse end face of the magnet (), and means of connecting the shim () to the magnet ().

Rotor for rotary electric machine comprising magnet element between two adjacent teeth

An electrical rotating machine rotor, in particular for a motor vehicle, comprising a central shaft, an annular core coaxial with the shaft and two polar wheels which are axially arranged on either side of the core, of the type wherein the shaft includes at least one drive section which is axially force-fitted into a fixing bore of at least one component of the rotor so as to secure in rotation at least one of the two polar wheels of the rotor to the shaft, an intermediate sleeve being radially interposed between each polar wheel and the central shaft, and on which sleeve is mounted said polar wheel. The invention also concerns a method for making such a rotor.

Rotor for an electrical machine comprising an intermediate sleeve interposed between at least one polar wheel and a shaft on which it is mounted

A method for producing a claw-pole rotor, including: a step of mounting polar wheels on the shaft in such a way that each tooth of a polar wheel is located in the existing space between two consecutive teeth of the other polar wheel; a step of machining the lateral faces facing two adjacent teeth, whereby an axial groove is machined in each lateral face; and a step of mounting a magnetic element between two adjacent teeth such that the magnetic element is received in the axial grooves. The method is characterized in that the step of machining lateral faces is carried out before the step of mounting polar wheels on the shaft. The invention also relates to a rotor obtained by such a method.

Method for producing a rotor comprising a step of machining grooves in the teeth of the poles, and rotor obtained by said method

An alternator for a vehicle comprises two pole pieces having interlaced poles () and magnets, the poles exhibiting grooves profiled along an axis () and accommodating the magnets, the profile completely preventing the magnets escaping from the grooves in a plane perpendicular to the axis (). It has, for each magnet (), a strip () interposed between one face () of the magnet and at least one of the grooves (), the strip () being produced from a material which is less hard than the magnet.

Alternator for a vehicle with take-up of play on the inter-pole magnets

The vehicle alternator comprises a rotor ( ) having interleaved polar horns ( ), at least one of the horns having, facing towards another one of the horns, a side face ( ) formed with a profiled groove ( ). The groove has one longitudinal end ( ) which is blind in a longitudinal direction of the groove.

Alternator with interpolar magnets for a motor vehicle

The vehicle alternator comprises a rotor having interleaved pole pieces, permanent magnets disposed between the pole pieces, and at least one magnet-support strip which extends over a circumferential outside face of the pole pieces.

Motor vehicle alternator with interpolar magnets

The invention concerns a vehicle alternator comprising a rotor including a shaft, two plates comprising nested pole horns, magnets extending between the pole horns, and members for maintaining the magnets. The maintaining members extend opposite an external surface of the axial end of the plates.
