Abstract
The utility model relates to an uncased AC permanent magnet servo motor stator, which comprises a stator magnet core formed by superposing a plurality of magnet core silicon steel plates; one or more than one adjacent silicon steel plate among the silicon steel plates rotates 90 DEG to each other; an end plate (3) which shares an axis and a side shape with the stator magnet core is respectively arranged at two ends of the stator magnet core; flanges are arranged at the outer edge of the end plates and the silicon steel plates; and the arrangement of the silicon steel plates allows the stator magnet core to eliminate vortex and at the same time to improve heat dissipation and allows a bigger area between the silicon steel plates for contacting the air. In addition, the interlaced silicon steel plates make the stator more elegant in appearance without a case.
Description
Technical field
The utility model relates to a kind of motor stator, especially relates to a kind of no shell alternating-current permanent-magnet servo motor stator.
Background technology
At present, the alternating-current permanent-magnet servo motor volume of producing is all smaller both at home and abroad, all adopt chlamydate design, but for alternating-current permanent-magnet servo motor large-scale, large volume, if still adopt housing designs, shell will very hugely could hold motor fully so, so, the shell cost of motor then can't be ignored, and for whole motor, shell has occupied very big cost.In addition, large-scale alternating-current permanent-magnet servo motor caloric value height, power is big, and housing designs can hinder radiating effect, also is a hidden danger of large-scale alternating-current permanent-magnet servo motor housing designs.In addition, the stator core in the common motor all is a simple superposition and constituting, and not only outward appearance is plain in this simple stack, for heat radiation also without any help.Thereby nowadays in a hurry need a kind of large-scale alternating-current permanent-magnet servo motor stator of design with good heat dissipation.
Summary of the invention
The utility model mainly is to solve the existing weak heat-dissipating of prior art, volume is big, cost is high technical problem, and a kind of good heat dissipation, volume is little, cost is low no shell alternating-current permanent-magnet servo motor stator are provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of no shell alternating-current permanent-magnet servo motor stator is provided, comprise by stacking the stator core that some magnetic core silicon steel sheets form, its special feature is, in described some silicon steel sheets, the above silicon steel sheet of adjacent a slice or a slice is rotated into 90 degree mutually, be provided with the end plate of and ipsilateral shape coaxial with stator core at the stator core two ends, end plate and silicon steel sheet outer have flange.Wherein stator core is overrided to form by some silicon steel sheets that are rotated into 90 degree mutually, not only reduced eddy current, and the angle that has allows and has certain space between the every silicon steel sheet end, can help heat radiation, the silicon steel sheet that interlocks in addition and superpose also makes stator core more attractive in appearance, fixing and outside connection of end plate makes whole stator can break away from shell fully before and after adding, and itself had the multiple advantage of firm, attractive in appearance and good heat dissipation.
As preferably, described silicon steel sheet is provided with two flanges, and 180 degree of being separated by, and described end plate is provided with four flanges, and adjacent two flanges 90 degree of being separated by, and the flange on the end plate matches with flange on the silicon steel sheet.When silicon steel sheet revolve turn 90 degrees after, all flanges of silicon steel sheet are still covered by the flange on the end plate, thereby have protected on the one hand silicon steel sheet, on the other hand can be by connecting the bolt of end plate and silicon steel sheet.
As preferably, the flange of described silicon steel sheet and end plate has corresponding bolt hole, by running through the bolt of end plate and silicon steel sheet.The bolt that runs through end plate and silicon steel sheet is that most convenient also makes one of the most firm method.
As preferably, in described some silicon steel sheets, the silicon steel sheet of adjacent a slice is rotated into 90 degree mutually.Every adjacent mutual angle of silicon steel sheet is all different.
As preferably, in described some silicon steel sheets, two adjacent silicon steel sheet is rotated into 90 degree mutually.The mutual angle of per two silicon steel sheet is all different.
As preferably, flange before and after the front and back end plate connects respectively.Under the situation that does not adopt housing designs, the end plate particular design of employing can reach the function that connects the motor body.
Therefore, the utlity model has rational in infrastructure, manufacturing process is simple, cost is low, structure is simplified, characteristics such as wide accommodation, the especially arrangement mode of the silicon steel sheet of Ti Chuing, can allow stator core when solving eddy current problem, can help heat radiation, have an area that more contacts between the silicon steel sheet of being separated by with air.In addition, Jiao Cuo silicon steel sheet also allow holder do not have under the situation of shell more attractive in appearance.

Accompanying drawing 2 is partial enlarged drawings of A;
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: accompanying drawing 1 is a kind of package assembly schematic diagram of the present utility model, comprise by stacking the stator core 2 that some magnetic core silicon steel sheets 1 form, in described some silicon steel sheets, adjacent a slice silicon steel sheet is rotated into 90 degree mutually, be provided with the end plate 3 of and ipsilateral shape coaxial with stator core at the stator core two ends, silicon steel sheet is provided with two flanges 4, and 180 degree of being separated by, described end plate is provided with four flanges, and adjacent two flanges be separated by 90 the degree, flange on the end plate matches with flange on the silicon steel sheet, four angle ends of silicon steel sheet and end plate all are provided with corresponding bolt hole 5, by running through the bolt of end plate and silicon steel sheet, flange before and after the front and back end plate connects respectively.Fig. 2 is staggered flange place.
When assembling, at first on fixed mount, stack first silicon steel sheet, second silicon steel sheet then differs an angle of 90 degrees with first silicon steel sheet and stacks up, the 3rd and second differs 90 degree and stacks up, the 3rd then can with first fit like a glove, so constantly laminate silicon steel sheet to the needed height of stator, become the stator core of motor stator, install end plate at the two ends of stator core then, the flange of end plate and the flange of silicon steel sheet match.Use the bolt that can run through all silicon steel sheets and end plate that stator core is fixing as a whole at last.
