STRUCTURE DE ROTOR À AIMANTS PERMANENTS
(ZH)
一种永磁转子结构
Abstract:
(EN)
A permanent magnet rotor structure comprises a rotor iron core (1) and a permanent magnet body (2). Several magnetic induction blocks (11) are arranged on the rotor icon core (1). Between two adjacent magnetic induction blocks (11), a radial groove (110) is formed for mounting the permanent magnet body (2). A block hook (111) protrudes on magnetic induction blocks (11) on two sides of an opening of the radial groove (110). An axial notch (21) is arranged on at least one outer side surface of the permanent magnet body (2); an axial protrusion (112) is arranged on at least one outer side surface of the magnetic induction blocks (11); the permanent magnet body (2) is mounted in the radial groove (110); and the axial protrusion (112) of the magnetic conduction blocks (11) is inlayed into the axial notch (21) of the permanent magnet body (2). Alternatively, an axial protrusion (22) is arranged on at least one outer side surface of the permanent magnet body (2); an axial notch (113) is arranged on at least one outer side surface of the magnetic conduction blocks (11); the permanent magnet body (2) is mounted in the radial groove (110; and the axial protrusion (22) of the permanent magnet body (2) is inlayed into the axial notch (113) of the magnetic induction blocks (11). The structure is simple, is convenient and firm to mount, and has high reliability and a long service life.
(FR)
L'invention porte sur une structure de rotor à aimants permanents qui comprend un noyau de fer de rotor (1) et un corps d'aimants permanents (2). Plusieurs blocs d'induction magnétique (11) sont disposés sur le noyau de fer de rotor (1). Entre deux blocs d'induction magnétique adjacents (11), une rainure radiale (110) est formée pour monter le corps d'aimants permanents (2). Un crochet de bloc (111) fait saillie sur des blocs d'induction magnétique (11) sur deux côtés d'une ouverture de la rainure radiale (110). Une encoche axiale (21) est disposée sur au moins une surface latérale externe du corps d'aimants permanents (2); une saillie axiale (112) est disposée sur au moins une surface latérale externe des blocs d'induction magnétique (11); le corps d'aimants permanents (2) est monté dans la rainure radiale (110); et la saillie axiale (112) des blocs de conduction magnétique (11) est incrustée dans l'encoche axiale (21) du corps d'aimants permanents (2). De manière alternative, une saillie axiale (22) est disposée sur au moins une surface latérale externe du corps d'aimants permanents (2); une encoche axiale (113) est disposée sur au moins une surface latérale externe des blocs de conduction magnétique (11); le corps d'aimants permanents (2) est monté dans la rainure radiale (110); et la saillie axiale (22) du corps d'aimants permanents (2) est incrustée dans l'encoche axiale (113) des blocs d'induction magnétique (11). La structure est simple, est commode et solide pour un montage, et possède une fiabilité élevée et une longue durée de vie.
(ZH)
一种永磁转子结构,包括转子铁芯(1)和永磁体(2),转子铁芯(1)上设置若干块导磁块(11),在相邻两导磁块(11)之间形成用于安装永磁体(2)的径向凹槽(110),在径向凹槽(110)的开口部的两侧导磁块(11)上凸出挡钩(111),永磁体(2)至少一个外侧表面设置轴向凹口(21),导磁块(11)至少一个外侧表面设置轴向凸起(112),永磁体(2)安装在径向凹槽(110)里面,导磁块(11)的轴向凸起(112)镶嵌在永磁体(2)的轴向凹口(21)里面;或者永磁体(2)至少一个外侧表面设置轴向凸起(22),导磁块(11)至少一个外侧表面设置轴向凹口(113),永磁体(2)安装在径向凹槽(110)里面,永磁体(2)的轴向凸起(22)镶嵌在导磁块(11)的轴向凹口(113)里面。该结构简单、安装方便牢靠、可靠性高、使用寿命长。
