Abstract
The present invention provides a method for mounting at least one magnetic pole of a rotor of a motor of a synchronous electrical rotating machine from elementary elements, the rotor including a hub. The method includes the following successive steps: forming the set of elementary elements of rectangular parallelepipedal shape by fixing at least two elementary elements to each other with an electrical insulator being interposed therebetween; the set of elementary elements being magnetizable; machining a main face of the set of elementary elements in order to form a cylindrical face having a radius substantially equal to the predefined radius of the hub; magnetizing the set of elementary elements; and fixing the set of elementary elements to the hub, the set of elementary elements forming at least a portion of the magnetic pole.
