摘要：
A rotor of an electric machine which might be used in a wind turbine is described. The rotor comprises (a) a mechanical support structure and (b) a magnet arrangement (560). The magnet arrangement comprises (b1) a first permanent magnet component (570a) and (b2) a second permanent magnet component (570b). The first (570a) and the second (570b) permanent magnet component are attached to said support and are arranged in axial direction of the rotor. The cross section in circumferential direction of the first permanent magnet component (570a) has a first shape and the cross section in circumferential direction of the second permanent magnet component (570b) has a second shape being different from the first shape.
