Abstract
(EN) A stator and an electric generator. The stator comprises a magnetic frame (1), a magnetic shoe (2), and at least one coil unit (3). The main body of the magnetic frame (1) is an annulus or a hollow regular polygon. The magnetic frame (1) is provided on the circumferential direction thereof with at least one gear groove (11). The coil unit (3) is arranged on the gear groove (11). The magnetic shoe (2) is arranged on two sides of the magnetic frame (1) and encloses the coil unit (3) within the magnetic shoe (2). The coil unit (3) comprises, sequentially stacked, an electrically conductive layer (31) and a magnetically permeable layer (32). The stator and the electric generator allow for reduced friction of a rotor and for increased energy conversion efficiency of the electric generator.
(FR) L'invention concerne un stator et un générateur, le stator comprenant un support magnétique (1), des bandes magnétiques (2) et au moins une unité d'enroulement (3). Le corps principal du support magnétique (1) de forme annulaire ou adoptant la forme d'un polygone régulier creux présente sur son pourtour au moins une encoche (11). Sur la rainure (11) vient l'unité d'enroulement (3) et de part et d'autre du support magnétique (1) viennent les bandes magnétiques (2) dans lesquelles est enroulée l'unité d'enroulement (3), laquelle comprend une couche conductrice d'électricité (31) formée d'éléments mis côte à côte et une couche magnétique (32). Ledit stator et ledit générateur permettent de réduire la résistance du rotor et d'augmenter l'efficacité de conversion d'énergie du générateur.
(ZH) 一种定子及发电机,定子包括导磁架(1)、导磁靴(2)和至少一个线圈单元(3)。所述导磁架(1)的主体为圆环形或中空正多边形,沿所述导磁架(1)的周向上均匀开设有至少一个齿槽(11)。所述线圈单元(3)设置在齿槽(11)上,所述导磁靴(2)设置在所述导磁架(1)的两侧且将所述线圈单元(3)包覆在所述导磁靴(2)内,所述线圈单元(3)包括依次层叠导电层(31)和导磁层(32)。该定子和发电机能够减小转子的阻力、提高发电机的能量转换效率。
