Abstract:
A claw-pole machine having a stator and a rotor, and an exciter coil that is wound on a solid core in the rotor, with the solid core extending in a 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 a plurality of tangential side surfaces, which alternate axially, starting from two sides, wherein a plurality of U-shaped metal sheets are attached to solid, radially-outward-oriented parts of the claw-pole fingers, with each U-shaped metal sheet being layered in a rotary axial direction to prevent eddy currents, and further wherein the U-shaped metal sheets, formed by stamping, extend around tangential side surfaces of the claw-pole fingers in a wedge shape so that the U-shape metal sheets cannot follow centrifugal forces.
