Abstract
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.
