A synchronous machine and a process for manufacturing a synchronous machine having permanent magnets arranged within the rotor such that the leak of magnetic flux generated by the magnets is reduced and having constructive characteristics that maximize the difference in the reluctances of direct axis and quadrature axis while providing the strength necessary for the good functioning of the equipment. Magnet-fixation grooves of the rotor are provided with elongated ends in a curved shape, a first elongated end extending from the first free end to a region adjacent the end of the rotor groove bottom, the first elongated end being configured from an opening in the rotor, forming reluctance-increase channels, a second elongated end of the fixation grooves being configured so as to form the reluctance-increase channel and extending from the respective second free-end portion toward the second free-end portion of the other fixation groove of the pair.
