Abstract
A method of manufacturing a claw-type magneto-electric rotor. The claw type rotor comprising magnetic material parts forming the poles of the rotor and amagnetic material parts separating the poles of opposite polarity confined in a hollow cylindrical casing in the shape of a body of revolution, wherein the casing is made from an amagnetic material. The method includes a step of filling the hollow cylinder with the magnetic material parts and amagnetic material parts and a step of isostatic compression of the combination of these parts and the hollow casing cylinder. Each magnetic or amagnetic material part is made from a plurality of nested, independent, matched and coaxial tube elements each having lateral edges, transverse ends and a lateral face having the exterior shape of the corresponding radial thickness of the magnetic or amagnetic material part concerned.
