A rotor assembly for an electromechanical transducer is provided. The rotor assembly comprises a mechanical support structure and a magnet arrangement having a first magnetic component part and a second magnetic component part. The first magnetic component part and the second magnetic component part are attached to the mechanical support structure and are arranged along an axial direction (Z) of the rotor assembly. With respect to the axial direction a first cross section of the first magnetic component part has a first shape and a second cross section of the second magnetic component part has a second shape being different from the first shape. It is further described an electromechanical transducer and a wind turbine, which are both equipped with such a rotor assembly.

A tubular body for an electrical machine is provided. The tubular body comprises a curved surface area, a first tooth and a second tooth. The tubular body is arrangable with respect to a further tubular body such that one of the tubular body or the further tubular body is rotatable with respect to the other one around a rotary axis. The first tooth and the second tooth extend from the curved surface area along a radial direction with respect to the rotary axis. The first tooth comprises a first side wall facing a second side wall of the second tooth, wherein the first side wall comprises a first section which is parallel to the second side wall such that a circumferential distance between the first section and the second side wall is constant along the radial direction.
