Permanent magnet generator with stator teeth made of sheets with oriented grains for on-board vehicle charging

A permanent magnet generator for on-board vehicle charging, the permanent magnet generator comprising:

• an external rotor;
• a stator assembly accommodated inside said external rotor and provided with a stator yoke, with a plurality of stator teeth extending from said stator yoke and with a plurality of conductive windings arranged around at least one portion of each of said stator teeth;
• and
• at least one permanent magnet associated with at least one portion of an internal wall of said external rotor and facing said stator assembly,
• wherein said stator yoke is made of magnetic steel sheet with non-oriented grains, and
• said stator teeth are made of magnetic steel sheet with oriented grains,
• wherein said permanent magnet generator further comprises coupling means between said stator yoke and said stator teeth, and
• wherein said stator yoke is a single-piece component comprising a plurality of coupling holes for directly mounting the stator assembly to an endothermic motor.
