Abstract[English]
A permanent magnet-assisted synchronous reluctance motor (10) (PMa SynRM) structure which addresses several challenges in conventional motor designs. By strategically incorporating permanent magnets (82,88,94) (PMs) into the motor (10) structure, the PMa SynRM structure improves the overall motor (10) performance by achieving increased reluctance-to-permanent magnet torque ratio, decreased torque ripple, reduced dependency on permanent magnets (82,88,94), optimized torque and power characteristics for dominant reluctance torque scenarios by designing for applicable and proper geometric dimensions, material characteristics, and winding layouts, and increased energy efficiency and lower environmental impact.[French]
L'invention concerne une structure de moteur à réluctance synchrone assisté par aimant permanent (10) (PMa SynRM) qui aborde plusieurs défis dans des conceptions de moteur classiques. En incorporant stratégiquement des aimants permanents (82, 88, 94) (PM) dans la structure de moteur (10), la structure PMa SynRM améliore les performances globales du moteur (10) en obtenant un rapport de couple de réluctance-aimant permanent accru, une ondulation de couple réduite, une dépendance réduite sur des aimants permanents (82, 88, 94), des caractéristiques de couple et de puissance optimisées pour des scénarios de couple de réluctance dominante par conception pour des dimensions géométriques, des caractéristiques de matériau et des agencements d'enroulement applicables et appropriés, et une efficacité énergétique accrue et un impact environnemental inférieur.
