Abstract
Described is a rotor (3) for an electrical machine (1) which comprises a rotor laminated core (6) divided into a plurality of sectors (B), in each of which there is arranged a permanent magnet assembly (4) which has two permanent magnets (13a, 13n) which are arranged in a V shape and which are positioned symmetrically with respect to a plane of symmetry (C) splitting the sector (B) into two half-sectors (D, D′). An outer contour (E) of the rotor laminated core (6) runs in each sector (B) symmetrically with respect to the plane of symmetry (C) and is formed in one half-sector (D, D′) by at least three different radii with just as many different centre points. The invention also relates to an electric machine (1) having such a rotor (3) and to a vehicle (17) having such an electric machine (1).
