Title
(DE) MOTORSTATOR
(EN) MOTOR STATOR
(FR) STATOR DE MOTEUR
Abstract
(EN) A motor stator structure includes multiple teeth 20, 20', 20" and multiple arched bridge sections 30, 30', 30" respectively connected between the tooth roots 21 of the adjacent teeth. Each of the arched bridge sections 30, 30', 30" has an arched section 31, 31' extending along two adjacent sides of a predetermined parallelogram. The motor stator structure further includes multiple enlarged sections a respectively positioned at the tooth roots of the teeth 20, 20', 20". Each of the arched bridge sections 30, 30', 30" is positioned outside the range of the corresponding enlarged section a. The motor stator structure is composed of multiple small stators 10" stacked on each other. At least two punched splits 40" are respectively positioned between the tooth roots of two adjacent teeth 20" to separate the adjacent teeth 20". The space of two ends of the arched bridge section is enlarged to increase the pass space of magnetic field.
(FR) La présente invention concerne un stator de moteur comprenant des dents (20, 20', 20'') multiples et des parties pont en arc (30, 30', 30'') multiples reliées séparément entre les bases (21) des dents de deux dents adjacentes. Chaque partie pont en arc (30, 30', 30'') présente un anneau circulaire (31, 31') s'étendant longitudinalement au niveau de deux bords latéraux adjacents d'un parallélogramme prédéfini. Le stator de moteur comprend également des orifices (a) multiples de zone élargie disposés séparément sur les positions des bases de dents des dents (20, 20', 20''). Les parties pont en arc (30, 30', 30'') sont disposées au-delà des rayons d'action des orifices (a) de zone élargie correspondants. Le stator de moteur est formé par empilement de multiples petits stators (10''). Au moins deux orifices de poussée et de coupe (40'') sont situés respectivement entre les bases des dents de dents (20'') adjacentes, et les orifices de poussée et de coupe (40'') séparent les dents adjacentes (20''). Au moyen de l'accroissement de l'espace au niveau de deux extrémités des parties pont en arc, le stator de moteur augmente l'espace de passage du champ magnétique.
