Title
(EN) SINGLE-PHASE ELECTRIC MOTOR AND CLOSED COMPRESSOR
(FR) MOTEUR ELECTRIQUE MONOPHASE ET COMPRESSEUR FERME
(JA) 単相電動機及び密閉形圧縮機
Abstract
(EN)
A high-efficient and inexpensive single-phase electric motor and a closed compressor using it is produced by ensuring a magnetic path of a stator iron core back and forming such a shape that the material scribing is preferable. The single-phase electric motor comprises a stator having an iron core formed of a laminate of electrical steel sheets and provided with slots and a single-phase two-pole distributed winding composed of main and auxiliary windings provided in the slots and a rotor disposed along the inner circumference surface of the stator with an air gap therebetween. The single-phase electric motor is characterized in that five or more generally linear cuts are made in the outer circumference portion of the stator iron core and a rectangle with straight lines including four cuts among the five or more cuts is formed.

L’invention concerne un moteur électrique monophasé bon marché à haut rendement et un compresseur fermé l’utilisant, le moteur étant fabriqué de façon à établir un chemin magnétique au dos d’un noyau de fer de stator et à présenter une forme favorisant la découpe de matière. Le moteur électrique monophasé comprend un stator doté d’un noyau de fer formé d’un stratifié de feuilles d’acier électriques et doté de fentes et d’un bobinage dipolaire distribué monophasé constitué de bobinages principal et auxiliaire montés dans les fentes, et un rotor disposé le long de la surface circonférentielle intérieure du stator, le stator et le rotor étant séparés par un entrefer. Le moteur électrique monophasé est caractérisé en ce qu’au moins cinq découpes généralement linéaires sont ménagées dans la partie circonférentielle extérieure du noyau de fer du stator et un rectangle constitué de quatre lignes droites incorporant quatre découpes parmi lesdites au moins cinq découpes est formé.
