Abstract
(EN) A motor stator comprises multiples teeth (20, 20', 20'') and multiple arch bridge portions (30, 30', 30'') separately connected between tooth roots (21) of two adjacent teeth. Each arch bridge portions (30, 30', 30'') has an arch ring (31, 31') extending along at two adjacent side edges of a preset parallelogram. The motor stator also comprises multiple enlarged area ports (a) separately located on the positions of the tooth roots of the teeth (20, 20', 20''). The arch bridge portions (30, 30', 30'') are located beyond the ranges of the corresponding enlarged area ports (a). The motor stator is formed by stacking up multiple small stators (10''). At least two pushing and cutting ports (40'') are respectively located between tooth roots of two adjacent teeth (20''), and the pushing and cutting ports (40'') separate the adjacent teeth (20''). By expanding the space at two ends of the arch bridge portions, the motor stator increases the passing space of the 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.
(ZH) 一种电机定子,包括多个齿(20,20',20'')和分别连接于相邻两齿的齿根(21)间的多个拱桥部(30,30',30'')。各拱桥部(30,30',30'')分别具有沿预定平行四边形两相邻侧边延伸的拱圈(31,31')。电机定子还包括分别位于各齿(20,20',20'')的齿根位置的多个放大区端口(a),各拱桥部(30,30',30'')位于对应放大区端口(a)的范围外。电机定子由多个小定子(10'')层叠而成,至少两个冲断口(40'')分别位于相邻两个齿(20'')的齿根部位间,冲断口(40'')分开相邻的齿(20'')。电机定子通过扩大拱桥部两端的空间,增加了磁场的通过空间。
