Pole shoes in a D.C. machine are designed to support the field coils, spread out the magnetic flux for better uniformity, and reduce the reluctance of the magnetic path. They do not directly function to reduce eddy current loss; instead, eddy current loss is typically reduced by laminating the core on which the pole shoes are mounted.
