Permanent magnets are mounted within an electrical machine in a pitched saw- tooth pattern around the rotor shaft. This focused flux configuration provides for improved magnet mounting strength without resort to bonding or taping; provides improved rotor and stator cooling by access to the axial generator air flow; and provides for a simpler and more easily manufactured design. A laminated version of this basic structure provides for reduced surface losses and self-heating.
L'invention concerne des aimants permanents qui sont montés à l'intérieur d'une machine électrique selon un motif en dents de scie orienté autour de l'arbre de rotor. Cette configuration à flux concentré permet une meilleure résistance de montage d'aimant sans recourir au collage ou au rubanage ; permet un meilleur refroidissement du rotor et du stator par accès à l'écoulement d'air de générateur axial ; et permet une conception plus simple et fabriquée plus facilement. Une version en couches de cette structure de base permet des pertes surfaciques réduites et un échauffement spontané réduit.
