Title
(EN) FLUX DIRECTING, POLE SPAN SETTING, FEATURE ON ROTOR LAMINATION OF AIR-COOLED ELECTRIC MOTOR/GENERATOR

Abstract
(EN)
A rotor having a plurality of laminations joined together and mountable on a shaft for rotation relative to a stator of a rotary electric machine arrangement has a solid section that surrounds an opening within which the shaft is receivable. The solid section includes an outside diameter, magnet receiving voids, and steps delimiting a plurality of pole spans from flux directing features at sides of each of the pole spans. Adjacent flux directing features between adjacent pole spans are disposed on opposite sides of scalloped areas or other such recesses, permitting cooling air flow past the rotor. The invention also concerns a lamination usable together with additional laminations to provide such a rotor, as well as an arrangement, such as an AC motor, generator, or motor/generator, including a stator and such a rotor.

Le rotor selon l'invention ayant une pluralité de stratifications jointes ensembles et montables sur un arbre pour une rotation par rapport à un stator d'un agencement de machine électrique rotative a une section solide qui entoure une ouverture dans laquelle peut se loger l'arbre. La section solide comprend un diamètre extérieur, des vides de logement d'aimants, et des échelons délimitant une pluralité de portées depuis des attributs d'orientation de flux sur des côtés de chacune des portées. Des attributs d'orientation de flux adjacents entre des portées adjacentes sont disposés sur les côtés opposés de zones festonnées ou d'autres évidements similaires, permettant à l'air de refroidissement de circuler au-delà du rotor. L'invention concerne aussi une stratification utilisable avec d'autres stratifications pour produire un tel rotor, ainsi qu'un agencement, par exemple un moteur à CA, un générateur, ou un moteur/générateur, comprenant un stator et un tel rotor.
