A multipole rotor is disclosed for an electric motor, the rotor having a rotor core and a plurality of individual permanent magnets, which are distributed over a circumference of the rotor and which,when seen in a cross-sectional view of the rotor orthogonal to an axis of the rotor, have a convex curvature on the side facing the air gap between a stator of the electric motor and the rotor. Four respective permanent magnets, which are juxtaposed in the circumferential direction of the rotor, define together a magnetic pole pair, the magnetization direction of each individual permanent magnet enclosing an angle between 30 DEG and 60 DEG with a reference plane extending through the axis of the rotor and through the center of the respective permanent magnet.
