An electric rotating machine includes an outer stator, and an inner stator arranged inside the outer stator in concentric relationship to the outer stator. The inner stator has a plurality of permanent magnets which contain iron-neodymium-boron. A rotor is arranged in concentric relationship to the outer stator and the inner stator between the outer stator and the inner stator. The rotor is configured for movement in relation to the outer stator and the inner stator and defines with the inner stator an internal air gap there between. Each permanent magnet of the inner stator has a north pole and a south pole on a side facing the internal air gap.
