Abstract

An electric motor has a means serving to prevent rotation with reference to the encircling frame (1) of the cylindrical stator stack in which the plates (6) have been bound together by an aluminium shell (7) cast thereupon. The means comprises an axial projection (8) on the shell which as the stator stack is being pushed in place enters an axial groove (9) in the frame (1) to prevent rotation. <IMAGE>

Description

8207310-7 Uppfinningen åsyftar att frambringa en tillförlitligare anord- ning som inte uppvisar de förut kända problemlösningarnas nackdelar. 8207310-7 The invention aims to provide a more reliable device. which do not exhibit the previously known problem solutions disadvantages.

Uppfinningen kännetecknas av att det axiella spåret befinner sig i ett ringformigt anslag inuti stommen, mot vilket stator- paketet skjuts i axiell riktning.The invention is characterized in that the axial groove is located in an annular stop inside the body, against which the stator the package is pushed in the axial direction.

Uppfinningen beskrivs i det följande med hänvisning till vid- liggande ritning, vari fig. l föreställer en elmotor enligt en utföringsform av upp- *finningen i skärning, och fig. 2 visar en del av motorns stomme och av aluminiumskalet sedda inifrån.The invention is described in the following with reference to horizontal drawing, in which Fig. 1 shows an electric motor according to an embodiment of the finding in the cut, and Fig. 2 shows a part of the engine body and of the aluminum shell seen from the inside.

I ritningen avser referensnumret l motorns stomme, 2 bottnen och 3 locket. I bottnen och locket har rotorns 4 axel 5 lager- förts.In the drawing, the reference number refers to the engine body, 2 the bottom and 3 lid. In the bottom and the lid, the shaft 4 of the rotor has 5 bearings. brought.

Enligt uppfinningen har statorpaketet, som omfattar plåtarna 6 och det därpå gjutna aluminiumskalet 7, skjutits in i stommen l. Locket 3 är därvid givetvis avtaget. Statorpaketet 6,7 blir rotationsfritt fastlåst i förhållande till stommen l i och med att aluminiumskalet 7 uppvisar ett axíellt utsprång 8 som när man skjuter statorpaketet på sin plats träder in i ett axiellt *spår 9 i stommen. Det axiella spåret 9 befinner sig i ett ringformigt anslag 10 inuti stommen 1, mot vilket statorpaketet skjuts i axiell riktning.According to the invention, the stator package comprising the plates 6 and the aluminum shell 7 cast thereon, is pushed into the body l. The lid 3 is then of course removed. The stator package 6.7 becomes rotationally locked in relation to the body 1 through that the aluminum shell 7 has an axial projection 8 as when one pushes the stator package into place entering an axial * track 9 in the frame. The axial groove 9 is in one annular stop 10 inside the body 1, against which the stator package is pushed in the axial direction.

Utsprånget 8 framställs lämpligast genom gjutning samtidigt som aluminiumskalet 7 gjuts på plåtarna 6. Likaså gör man spåret 9 lämpligast samtidigt i samband med gjutning av stommen l. I tillägg till läsningen som utsprånget 8 och spåret 9 utgör kan man naturligt använda ett krympförband 8207310-7 mellan statorpaketet 6,7 och stommen l. Detta krympförband kan emellertid vara relativt löst så att byte av statorpaket underlättas.The protrusion 8 is most suitably made by casting simultaneously as the aluminum shell 7 is cast on the plates 6. The same is done groove 9 is most suitable at the same time in connection with casting of the body l. In addition to the reading as the projection 8 and the groove 9 constitutes, one can naturally use a shrink joint 8207310-7 between the stator package 6,7 and the body 1. This shrink joint can however, be relatively loose so as to replace the stator package facilitated.

Det är klart för en fackman i branschen att uppfinningens olika utföringsformer kan Variera inom ramen för efterstående patentkrav. Detta gäller framför allt formen och storleken av utsprånget 8 och spåret 9.It is clear to one skilled in the art that the invention different embodiments may vary within the scope of the following patent claims. This applies above all to the shape and size of the projection 8 and the groove 9.
