Patent ID: 7969061

Claim:
A method of producing a claw rotor ( 12 ) for a rotating electrical machine, comprising a central shaft ( 14 ) and two magnet wheels ( 20 , 22 ), each magnet wheel ( 20 , 22 ) extending radially overall with respect to the main axis of the central shaft ( 14 ), and comprising at its outer periphery a series of overall trapezoidal shaped teeth ( 30 ), which extend ( 30 ) axially in the direction of the other magnet wheel ( 22 ), comprising the steps of: a step of mounting the magnet wheels ( 20 , 22 ) on the shaft ( 14 ) so that each tooth ( 30 ) of one magnet wheel ( 20 , 22 ) is situated in the space existing between two consecutive teeth ( 30 ) of the other magnet wheel( 20 ); a step of machining facing lateral faces ( 68 ) of two adjacent teeth ( 30 ) each belonging to a magnet wheel ( 20 , 22 ), which consists of machining an axial groove ( 70 ) in each lateral face ( 68 ); a step of mounting a magnetic element ( 62 ) between two adjacent teeth ( 30 ), so that the magnetic element ( 62 ) is housed partly in the axial grooves ( 70 ) machined in the facing lateral faces ( 68 ) of two adjacent teeth ( 30 ), wherein the step of machining the lateral faces ( 68 ) of two adjacent teeth ( 30 ) is implemented before the step of mounting the magnet wheels ( 20 , 22 ) on the shaft ( 14 ) directly or indirectly.
