ABSTRACT OF THE DISCLOSURE A rotor for a synchronous salient-pole electrical machine, having a rim built up in annular layers consisting of segments provided with recesses forming slots on the rim circumference, in which alike poles are mounted and which form a plurality of groups distributed in series over the rim circumference, the distances between the adjacent slots in all the groups being the same and different than equal distances between the adjacent slots of different groups. In some of the segments, the adjacent recesses are spaced from each other by the same distance equal to the distance between the slots within a group. In other segments, mounted in those layers of the rim, wherein between the places of location of the adjacent slots of different groups, there are no joints between the segments, the adjacent recesses are arranged in the same manner except for two adjacent recesses in each segment, located at a distance equal to the distance between the adjacent slots of different groups and coincident, upon the installation, with the places of location of these slots. The invention provides an improved emf curve shape of the electrical machine due to suppression of the tooth harmonics, at rather minor complication of the production of parts of the rotor, its assembly and repair.
