Title
(EN) ELECTRIC MACHINE WITH PERMANENT MAGNET ROTOR
(FR) MACHINE ÉLECTRIQUE COMPRENANT UN ROTOR À AIMANT PERMANENT
Abstract
(EN)
A multi-phase electric machine may include a stator, and a rotor for rotating within the stator, the rotor including poles having combination magnet pieces with varying strengths and dimensions creating a non-sinusoidal back EMF. In one aspect, a multi-phase electric machine may include a stator, and a rotor for spinning within the stator,the rotor includes a plurality of poles having magnet assemblies includes at least a low strength magnet and a high strength magnet therein for creating a non-sinusoidal back EMF. In other aspects, a multi-phase electric machine of the present disclosure includes a stator, and a rotor for spinning within the stator, the rotor including a plurality of poles having magnet assemblies includes at least a first magnet and second magnet therein for creating a non-sinusoidal back EMF wherein a strength ratio of the first magnet and second magnet greater than the absolute value of 1.

La présente invention concerne une machine électrique polyphasée pouvant comprendre un stator et un rotor destiné à tourner à l'intérieur du stator, le rotor comprenant des pôles comprenant des pièces aimantées de combinaison ayant des résistances et des dimensions variables créant une force contre-électromotrice non sinusoïdale. Selon un aspect, une machine électrique polyphasée peut comprendre un stator et un rotor destiné à tourner à l'intérieur du stator, le rotor comprend une pluralité de pôles comprenant des ensembles aimants comprenant au moins un aimant à faible résistance et un aimant à haute résistance à l'intérieur de ce dernier permettant de créer une force contre-électromotrice non sinusoïdale. Dans d'autres aspects, une machine électrique polyphasée de la présente invention comprend un stator et un rotor destiné à tourner à l'intérieur du stator, le rotor comprenant une pluralité de pôles comprenant des ensembles aimants comprenant au moins un premier aimant et un second aimant à l'intérieur de ce dernier permettant de créer une force contre-électromotrice non sinusoïdale, un rapport de résistance du premier aimant et du second aimant étant supérieur à la valeur absolue de 1.
