vsosnsu-1 2 De lameller som är belägna upp till ca. 10 mm från respektive statorände är vridna 900 relativt de övriga lamellerna. Därmed bildas i spåren lä radiellt riktade kanter l5, vilka är anordnade för fixering av en lagersköld 16. Vid mønteringen av lagerskölden 16 på statorn 10 skjutas skölden över stator- änden in över spåret lh. För att enkelt bestämma inskjutningslängden kan styr- klackar vara anordnade. I Fig. 1 visas dessa bestå av i skölden, som består av plåt, utstansade flikar 17 som är inåtböjda. Flikarna är jämnt fördelade runt lager- sköldens periferi och anligger vid monterad lagersköld mot statorändytan. När sköl- den befinner sig i detta läge, anbringas ett verktyg som pressar ner material från lagerskölden i spåret lä och mot kanten 15. Detta utförs samtidigt i alla spår lä. De partier av lagerskölden vilka nedpressas i spåren lh har beteckningen 18. Som framgår ovan sker den erforderliga bearbetningen av statorlamellerna ll redan vid tillverkningen av dessa. Inför monteringen av motorn fordras sålunda ingen efterbearbetning av statorpaketet. Då material från lagerskölden i en opera- tion direkt pressas ned i tillhörande spår och mot den radiella kanten för bildande av ett nitförband, erfordras ej heller någon förberedande bearbetning av lager- skölden. Det ovan beskrivna och på ritningen visade utföringsexemplet är inte avsett att i något avseende begränsa uppfinningen, vars omfång endast bestäms av efterföljande patentkrav. P a t e n t k r a v _vsosnsu-1 2 The slats located up to approx. 10 mm from each stator end are turned 900 relative to the other slats. Thus, radially directed edges 15 are formed in the grooves 1a, which are arranged for fixing a bearing shield 16. When mounting the bearing shield 16 on the stator 10, the shield is pushed over the stator end over the groove 1h. To easily determine the insertion length, guide lugs can be arranged. In Fig. 1 these are shown to consist of in the shield, which consists of sheet metal, punched-out tabs 17 which are bent inwards. The tabs are evenly distributed around the periphery of the bearing shield and abut when the bearing shield is mounted against the stator end surface. When the shields are in this position, a tool is applied which presses material from the bearing shield into the groove lä and towards the edge 15. This is done simultaneously in all grooves lä. The parts of the bearing shield which are depressed in the grooves 1h have the designation 18. As can be seen above, the required machining of the stator lamellae 11 already takes place during the manufacture of these. Thus, prior to mounting the motor, no post-processing of the stator package is required. When material from the bearing shield in an operation is directly pressed down into the associated groove and against the radial edge to form a rivet joint, no preparatory machining of the bearing shield is required either. The exemplary embodiment described above and shown in the drawing is not intended to limit the invention in any respect, the scope of which is determined only by the following claims.
