ABSTRACT:
A permanent magnet alternator includes a stator core having outwardly projecting teeth and further includes a plurality of permanent magnets surrounding the stator core. The stator core is formed from a continuous, helically wound metallic strip having a plurality of teeth defined between slots formed in one edge thereof. The stator core is formed by winding the strip edgewise around a cylindrical mandrel. To facilitate winding and avoid distortion, arcuate regions, conforming to the curve of the mandrel, are formed in the strip opposite the teeth.
