Abstract: A rotor for a multipolar synchronous electric machine including a plurality of salient poles, each salient pole being surrounded by an induction coil; a ring integrating the plurality of salient poles; wherein each salient pole includes a polar body integral with the ring; two removable pole tips facing each other on either side of the polar body; front parts provided along the ends of the polar body, to radially maintain the induction coil in a transverse portion thereof; the polar body including two slots formed on either side of the polar body and having a shape adapted for receiving the pole tips; the front parts blocking the displacements of the pole tips in the slots.
Abstract: A rotor for a multipolar synchronous rotating machine includes a plurality of salient poles, each salient pole including a polar body and being surrounded by an induction coil including a plurality of layers of coiled wire; a plurality of spacers such that each spacer of the plurality of spacers creates a first spacing between two successive layers of coiled wire of the plurality of layers for the circulation of coolant between each layer of coiled wire of the plurality of layers, the rotor including a second spacing between the polar body and each layer of coiled wire of the plurality of layers for the circulation of the coolant between the induction coil and the polar body.

Abstract: A rotor of a multipolar synchronous electric machine, with salient poles, includes a plurality of salient poles and a source of magnetomotive force, distributed on each of the salient poles, configured to generate a magnetic flux configured to encompass the armature of a stator, a part of the magnetic flux generated by the source of magnetomotive force, designated leakage flux, being dispersed between the salient poles of the rotor; the rotor including a magnetic compensation source configured to compensate the leakages of magnetic flux dispersed between the salient poles, the compensation source being dimensioned so as to compensate at least a part of the leakage flux.
Abstract: A stator for a rotating electrical machine, includes a housing including an outer casing and two end plates, a lantern ring made of a stack of magnetic plates supported by a frame made of flanges connected by bars; wherein the housing includes intermediate plates that are semicircular in shape and which form a cradle that is capable of supporting the lantern ring, the flanges are semicircular in shape and adapted so as to match the semicircular shape of the intermediate plates of the housing, when the lantern ring is placed inside the housing, the flanges including an upper part that has two vertical parallel edges that can be rigidly attached to the outer casing of the housing.
