Abstract

The invention concerns a transverse flux electrical machine operating with alternating current, having a first element having an alternate arrangement of excitation cores and of flux return cores and a winding of electrical conductors, the winding of electrical conductors being wound as a toroid, inside all said excitation cores; a second element having an exciter section comprising two toothed magnetic structures, each toothed magnetic structure comprising a number of slots equal in number to the total number of excitation cores and of flux return cores, the corresponding slots of each magnetic structure being toothed by being aligned; a magnetized sub-assembly is inserted inside each indentation so that an alternating arrangement of magnetic north poles and south poles is produced in each of these magnetic toothed structures of said exciter section; an air gap between the first element and the second element; at least one of the first element and of the second element being capable of rotating around a rotation axis that is common to the first element and to the second element.
