Title (EN) STATOR PUNCHING, STATOR ASSEMBLY AND EXTERNAL ROTOR MOTOR
(FR) TÔLE DE STATOR, ENSEMBLE STATOR ET MOTEUR À ROTOR EXTERNE
(ZH) 定子冲片、定子组件及外转子电机
Abstract:
(EN) Disclosed are a stator punching, a stator assembly and an external rotor motor. The stator punching comprises a punching body (1) with a central hole, the punching body (1) comprises an annular yoke (10) and a plurality of first teeth (11) and second teeth (12) extending outward from the outer edge of the annular yoke (10), the first teeth (11) and the second teeth (12) are arranged alternately in a circumferential direction, each of the first teeth (11) comprises a common tooth root (111) and at least four projected teeth (112) extending outward from the common tooth root (111), a first embedding wire slot (13) is formed between each two adjacent projected teeth (112), a second embedding wire slot (14) is formed between adjacent first tooth (11) and second tooth (12), and the depth of the first embedding wire slot (13) in the radial direction of the punching body (1) is less than the depth of the second embedding wire slot (14) in the radial direction of the punching body (1). The stator punching can improve the performance of the motor.
(FR) L'invention porte sur une tôle de stator, un ensemble stator et un moteur à rotor externe. La tôle de stator comprend un corps de tôle (1) pourvu d'un trou central, le corps de tôle (1) comprend une culasse annulaire (10) et une pluralité de premières dents (11) et secondes dents (12) s'étendant vers l'extérieur depuis le bord extérieur de la culasse annulaire (10), les première dents (11) et les secondes dents (12) sont disposées en alternance dans une direction circonférentielle, chacune des premières dents (11) comporte une racine dentaire (111) commune et au moins quatre dents saillantes (112) s'étendant vers l'extérieur à partir de la racine dentaire (111) commune, une première fente d'incorporation de fil (13) est formée entre chaque deux dents saillantes (112) adjacentes, une seconde fente d'incorporation de fil (14) est formée entre de première dents (11) et secondes dents (12) adjacentes, et la profondeur de la première fente d'incorporation de fil (13) dans la direction radiale du corps de tôle (1) est inférieure à la profondeur de la seconde fente d'incorporation de fil (14) dans la direction radiale du corps de tôle (1). La tôle de stator peut améliorer le rendement du moteur.
(ZH) 一种定子冲片、定子组件及外转子电机,定子冲片包括带有中心孔的冲片本体(1),冲片本体(1)包括环形轭部(10)和从环形轭部(10)外侧边缘上往外伸出的若干第一齿部(11)和第二齿部(12),第一齿部(11)和第二齿部(12)交替周向排列,第一齿部(11)包括公用齿根部(111)、从公用齿根部(111)上往外伸出的至少4个凸齿(112),相邻的2个凸齿(112)之间形成第一相嵌线槽(13),相邻的第一齿部(11)和第二齿部(12)之间形成第二相嵌线槽(14),第一相嵌线槽(13)沿冲片本体(1)径向方向的深度浅于第二相嵌线槽(14)沿冲片本体(1)径向方向的深度,该定子冲片可以改善电机性能。
