Definitions
- the invention relates to a method for assembling form coils or tooth coils in grooves of a laminated core of a dyna moelectric machine and auxiliary elements for mounting these coils in a laminated core.
- Stators or stator segments of dynamoelectric machines have coils in a layered laminated core in order to drive an Ar work machine through electromagnetic interaction with a rotor or to generate electrical energy through the driven rotor.
- a groove lining is known to be used as a sliding aid and protection of the insulation.
- this slot lining can only provide insufficient protection against damage to the insulation of preformed coils and tooth coils during introduction into the slot.
- the invention is based on the object of a method for the introduction of preformed coils or tooth coils in grooves of stators or stator segments that close damage to the insulation of preformed coils or Zahnspu len through teeth of the laminated core during insertion.
- the problem is solved by a method for assembling prefabricated preformed coils or toothed coils on a layered laminated core to form a stator segment or stator through the following steps:
- auxiliary element to facilitate assembly of form or Zahnspu len in grooves of a laminated core, the auxiliary element in particular having a special isosceles triangle-like basic structure with facing curved legs.
- auxiliary element is provided at least at the front ends of a laminated core, which ensures a Füh tion of these coils in the groove of the laminated core in a radial assembly of the form or toothed coils in the grooves of the laminated core. This in particular avoids damage to the insulation caused by the edges of the teeth.
- the form or tooth coils are open or closed Spu sources, which have a solid insulated conductor or individual ge mutually insulated sub-conductors. These sub-conductors, which are insulated from one another, are usually surrounded by main insulation. The main insulation is in particular present in the intended groove area of a dynamo-electric machine.
- the auxiliary elements are preferably placed on the pressure fingers so that contact with the sharp edges of the teeth in the area of the end faces of the laminated core with the insulation of the Form and tooth coils are avoided.
- the width of the pressure fingers is less than the width of the teeth, so that the auxiliary elements can ensure that the coils are guided without reducing the width of the groove during assembly.
- Such a laminated core can also be constructed from partial laminated cores, viewed in the axial direction, which are each separated from one another by spacers.
- auxiliary elements are not only to be arranged on the end faces, but also, for example, on the spacers between the partial laminated cores. This reduces contact with the insulation and the sharp-edged teeth.
- the auxiliary element is designed in the form of a triangle, the two legs of a triangle formed at the same time having a kink.
- This kink ensures the guidance of the mold or tooth coils in the area of the tooth during assembly.
- the legs of the triangle can also be curved.
- the two legs of this isosceles triangle are extended over the hypotenuse of this triangle, so that a fixation on pressure fingers, on the metal sheets or on the spacer can take place via these extended legs.
- This fi xing can be improved by snap elements on the extended legs.
- FIG 1 A perspective view of a stator
- FIG 5 placing a tooth coil in the grooves of a laminated core
- FIG. 6 shows a wind power plant shown in principle.
- FIG. 1 shows a perspective view of a stator segment 5, with a toothed coil 16 in a groove 6.
- the laminated core 26 is divided into partial laminated cores 12, which are spaced apart from one another by means of spacers 8.
- FIG. 2 shows a partial laminated core 12 at one axial end of the laminated core 26, the partial laminated core 12 having a pressure plate 1 with pressure fingers 2 which are used to compact the laminated core 26.
- the auxiliary element 7 has a fundamental triangular shape.
- the triangle has two identical leg sides 15, each of which has a kink 18 in the upper part. This kink 18 makes it easier to guide a preformed coil or a toothed coil 16 onto the tooth 3 or into the groove 6.
- the auxiliary element 7 should have good sliding properties, in particular above the bend 18, in order to prevent the Spu le from tilting during the assembly process.
- the auxiliary element 7 is made of a slidable material, such as glass hard fabric or PTFE or another hard plastic. It can also be made of a metal, in particular steel.
- a coating e.g. a sliding film
- This cover can be replaced when it is worn out.
- Snap elements 27 can improve the temporary fixation of the auxiliary elements 7 on the tooth 3 or on the pressure finger 2.
- the tooth width 4, in particular in the area of the tooth tip 13, is the same or slightly smaller (approx. 0 to 3 mm depending on the dimension of the arrangement) than the width 10 of the auxiliary element 7 in this area. In this way, contact of the insulation with the edges of the tooth tip 13 is now avoided in any case during assembly.
- the width 10 of the auxiliary element 7 is equal to the tooth width 4 or slightly larger.
- an eyelet 11 is provided in the upper area of the auxiliary element 7.
- FIG. 4 shows a basic assembly process in which a toothed coil 16 is placed in the grooves 6.
- An auxiliary element 7 with a width 10 is positioned on the pressure fingers 2 and thus prevents the insulation of the coil 16 from coming into contact with the edges of the laminated core 26 or partial laminated core 12.
- auxiliary element 7 is now pulled off with the aid of a recess 11, in particular an eyelet, and placed on the adjacent or another pressure finger 2 and thus the process of radial insertion of the coils 16 is repeated.
- At least two auxiliary elements 7 are required per coil, which are each arranged on an end face of the laminated core 26 for the assembly process.
- a stator or a stator segment 5 or stator segments 5 for a generator 21 of a wind power plant 20 according to FIG. 6 with air cooling is thus provided, with cooling air 23 being passed through gaps between the laminated cores 12 of the laminated core 26 to cool the stator.
