Title
(EN) STATOR USED IN AN ELECTRICAL MOTOR OR GENERATOR WITH LOW LOSS MAGNETIC MATERIAL AND METHOD OF MANUFACTURING A STATOR
(FR) STATOR UTILISÉ DANS UN MOTEUR OU UN GÉNÉRATEUR ÉLECTRIQUE COMPORTANT UN MATÉRIAU MAGNÉTIQUE À FAIBLE PERTE ET PROCÉDÉ DE FABRICATION D'UN STATOR
Abstract
(EN)
A stator for an electrical motor or generator and method for manufacturing such stator includes providing a plurality of teeth and joining the teeth with a yoke. An electrically conductive winding is applied around each of the teeth. The teeth and/or yoke may be made from a stack of low-loss magnetic material sheets. The teeth and/or yoke may be made by folding a stack of magnetic material sheets.
(FR)
L'invention porte sur un stator pour un moteur ou un générateur électrique et sur un procédé de fabrication d'un tel stator, lequel procédé consiste à fournir une pluralité de dents et à assembler les dents avec une fourche. Un bobinage électroconducteur est appliqué autour de chacune des dents. Les dents et/ou la fourche peuvent être fabriquées à partir d'une pile de feuilles de matériau magnétique à faible perte. Les dents et/ou la fourche peuvent être fabriquées par pliage d'une pile de feuilles de matériau magnétique.
