Abstract
A claw-pole machine has a stator and a rotor, and an exciter coil that is wound on a solid core in the rotor. The solid core extends in the radial direction into two claw magnet wheels that end in a plurality of claw-pole fingers, having a plurality of solid, radially-outward-oriented parts, and has a plurality of tangential side surfaces, which alternate axially, starting from two sides, wherein a plurality of U-shaped metal sheets are attached to the solid, radially-outward-oriented parts of the claw-pole fingers. The U-shaped metal sheets are layered one on top of the other in the axial direction to prevent eddy currents.
