摘要： The electric machine comprises a rotor (100) and a stator (200) surrounding the rotor (100). The stator (200) comprises a cylindrical stator core (210) having a laminated structure and slots (213) for a stator winding (211) and a stator frame (220) surrounding the stator core (210). The stator core (210) is attached with fastening brackets (300) by means of fastening means (350) based on a compression joint to the stator frame (220). The stator frame (220) comprises two opposite end constructions (221, 222) and at least one frame plate (223, 223A, 223B, 223C, 223D) located between the end constructions (221, 222). Back beams (212) extending in the axial (X-X) direction of the stator (200) are attached to an outer surface of the stator core (210). Each fastening bracket (300) comprises two perpendicular branches (310, 320), whereby a first branch (310) is attached to the stator frame plate (223, 223A, 223B, 223C, 223D) and a second branch (320) is attached to the back beam (212) by means of fastening means (350) based on a compression joint. The fastening means (350) passes through openings (311) in each branch (310, 320). The openings (311) are dimensioned to allow a small movement of the fastening means (350) in the openings (311) so that the stator core (210) can be centralized in a radial direction (R) and in an axial direction (X-X) in relation to the stator frame (220) before the fastening means (350) are tightened in order to lock the stator core (210) to the stator frame (220).
摘要翻译：电机包括转子（100）和围绕转子（100）的定子（200）。定子（200）包括具有层叠结构的圆柱形定子铁心（210）和用于定子绕组（211）的定子架（220）和围绕定子铁心（210）的定子框架（220）。定子铁心（210）通过基于与定子架（220）的压接头的紧固装置（350）附接有紧固支架（300）。定子框架（220）包括位于端部构造（221,222）之间的两个相对端构造（221,222）和至少一个框架板（223,223A，223B，223C，223D）。在定子（200）的轴向（X-X）方向上延伸的后梁（212）附接到定子铁芯（210）的外表面。每个紧固支架（300）包括两个垂直分支（310,320），由此第一分支（310）附接到定子框架板（223,223A，223B，223C，223D），并且第二分支（320）被附接通过基于压缩接头的紧固装置（350）连接到后梁（212）。紧固装置（350）穿过每个分支（310,320）中的开口（311）。开口（311）的尺寸被设计成允许紧固装置（350）在开口（311）中的小的移动，使得定子芯（210）可以在径向方向（R）和轴向方向（XX ）相对于定子框架（220）在紧固装置（350）被紧固以便将定子芯（210）锁定到定子框架（220）之前。
