Abstract
The utility model relates to a motor technical field discloses a fixed knot of segmental punching constructs for fix the iron core on the frame, the iron core sectorially comprises towards the piece closed assembly a plurality of, lies in the fixed plate at iron core both ends on locating the frame, is equipped with a plurality of notches of evenly distributed on the outer circumference of segmental punching, and the notch stack of all segmental punchings constitutes the spacing groove, and this limiting groove is equipped with the mounting that is used for fixed segmental punching, the both ends and the fixed plate fixed connection of this mounting. Above -mentioned scheme, adopts simultaneously and takes tangential half -circular arc notch so reduce the magnetic field loss to the minimum because the area of recess obviously is lighter than the bolt through -hole, and is littleer than the contained angle department magnetic field loss of keyway commonly used, has reduced the influence to the motor operation.
Description
Technical field
This utility model relates to technical field of motors.
Background technology
Stator core is the vitals constituting motor magnetic flux loop and fixed stator coils, and it is compressed by punching and various securing member and constitutes an entirety.Stator core typically requires and is fixed on the enterprising enforcement use of frame, current fixed form is, the segmental punching being stacked is cascaded by bolt and is fixed, the program must have through hole on some segmental punchings, bolt this through hole restriction site of traverse, fixing plate on support is positioned at segmental punching two ends, and fastens with nut at the two ends of bolt, enables segmental punching to fasten.Having drawbacks in that of such scheme need to process the hole for bolt traverse, complex steps in punching, changes the Distribution of Magnetic Field of segmental punching simultaneously, affects the stressing conditions of iron core.
Utility model content
This utility model is intended to provide the fixed structure of a kind of segmental punching, to simplify installation procedure, avoids the distribution of the magnetic force to segmental punching to impact simultaneously.
This programme provides following base case: the fixed structure of segmental punching, for iron core is fixed on support, iron core is made up of some segmental punching closed assemblies, including the fixing plate being located on support to be positioned at iron core two ends, the excircle of segmental punching is provided with equally distributed some recesses, the recess superposition of all segmental punchings constitutes stopper slot, is provided with the fixture for fixed sectors punching in this stopper slot, and the two ends of this fixture and fixing plate are fixed and connected.
Beneficial effect: the stack up fixing plate at composition stopper slot, fixture and iron core two ends of the recess that segmental punching is processed on excircle is connected so that whole iron core can be fixed；Adopting such scheme, owing to the area of recess is significantly less than bolt hole of the prior art, so being reduced to by magnetic losses minimum, installation procedure becomes simple and convenient simultaneously.
Prioritization scheme one: described fixture is key, the two ends of key and the welding of fixing plate, the mounting means of key is simple and firm, and welding procedure is simply without doing too much processing to fixing plate.
Prioritization scheme two: described fixture is bolt, two ends and the fixing plate of this bolt are fastened by nut；Bolt is connected as removably connecting, it is simple to installation and removal.
Prioritization scheme three: described recess be shaped as arc, inwall is round and smooth, it is to avoid the loss in magnetic field, angle, reduces the impact that motor is run.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fixed structure of this utility model segmental punching；
Fig. 2 is the structural representation at A place in Fig. 1；
Fig. 3 is the structural representation that segmental punching is installed.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: segmental punching 1, recess 2, key 3, fixing plate 4, bolt 5.
Embodiment 1: basic as shown in accompanying drawing 1, Fig. 2, the fixed structure of the segmental punching 1 in this programme, iron core is made up of some segmental punching 1 closed assemblies, and it is welded on support to be positioned at the fixing plate 4 at iron core two ends, the excircle of segmental punching 1 has equally distributed some recesses 2, the shape of cross section of recess 2 is circular arc, and recess 2 superposition of some segmental punchings 1 constitutes elongated keyway, is provided with the key 3 for fixed sectors punching 1 in this keyway；Being interference fit between key 3 and keyway, the two ends of key 3 are connected on fixing plate 4.
Operation principle: the recess 2 that segmental punching 1 is processed on excircle stacks up composition keyway, key 3 is connected with the fixing plate 4 at iron core two ends, whole iron core can be fixed, owing to the area of groove is significantly less than bolt 5 through hole, so magnetic losses being reduced to minimum, adopt circular arc recess 2 simultaneously, less than the angle magnetic losses of conventional keyway, reduce the impact that motor is run.
Embodiment 2: basic as shown in accompanying drawing 1 and Fig. 3, and embodiment 1 the difference is that, the bolt 5 for fixed sectors punching 1 is installed in this keyway, the two ends of bolt 5 utilize nut to be connected on fixing plate 4.Adopting bolt 5 to be fixed, the mode screwed is installed more laborsaving.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
