A permanent magnet rotor alternator is disclosed having a one-piece, rotor hub/flywheel/starting gear. Three high permanence ceramic permanent magnets provide a rotor having a contiguous ring of twelve alternating poles which allows for higher alternator efficiency. The magnets are ceramic and are adhesively bound to the rotor hub, which is driven by an extended cran shaft. The rotor rotates within a wound stator assembly of which the laminated stator core is a part of the alternator's frame assembly, and thus, serves as a shield should a rotor magnet come loose.
L'invention concerne un alternateur de rotor à aimant permanent comportant un moyeu/volant/engrenage de démarrage monobloc. Trois aimants permanents à forte rémanence, en céramique, constituent un rotor formé d'un anneau contigu de douze pôles alternatifs et lui confèrent un haut rendement. Les aimants en céramique sont fixés par collage au moyeu du rotor, qui est actionné par un arbre allongé. Le rotor tourne à l'intérieur d'un ensemble stator bobiné dont le noyau feuilleté fait partie d'un ensemble carcasse de l'alternateur et sert donc de protection au cas où un aimant du rotor se détacherait.
