ABSTRACT:
A permanent magnet-excited d-c machine including a stator, a plurality of flux-conducting pieces disposed in the stator, and a plurality of tangentially magnetized permanent magnets disposed in the stator between each of the flux-conducting pieces. Compensation slots are provided in the flux-conducting pieces on both sides of each of the permanent magnets and form a compensation tooth on the flux-conducting pieces between each of the slots and the permanent magnets in the stator. A winding is disposed in the slots adjacent each magnet and is looped around each magnet and each compensation tooth disposed between the compensation slots.
