Description

lérêlfc% tekirm * i & forvk or iramfefetektorrrrrrrrrrrrrrrrrrrrr to seal off the brackets containing the electromechanical or current ducts for the sealing of the brick top, which is formed as a straight block where one of the parallel sheets of the slab is curved, the other side parallel sheet

The rotor of an electric motor and its anteroom comprise poles separated from each other by grooves, most of which are coils of copper wire, but above all of the rolls due to the stabilization of the system against vibrations, introducing these grooves to the tea with the zeros.

Such closures are described, for example, in the document OE 11 2 ÖÖS ÖQ4 SI6 A1 ti *, especially for larger Induction devices, where finished rolls are placed in the grooves, which are then closed with their closures. their parallel cards face the coils and the air gap. In most cases, the pellets are made of plastic, especially glass fiber reinforced plastics pFkfe), on the one hand, a layered structure, on the other hand, is a magnetic material cap, such as iron powder. The latter is used to impart a magnetic property to the wedge, thereby improving the starting current. the ocos és and the load current, :: valimfot are reduced by iron losses, which results in a lower heat dissipation. The wedge of the wedges is mostly made of plywood, milling. The cross section of the bars fits into the groove to provide a more stable position in the groove :. Figure 1 shows a cross-sectional view of some of the known locks, most of which are trapezoidal at the edges so that the wedges, even when crossing the tolerance limits, are sure to be poured into the cuff, depending on their size: higher or lower on the bronze teeth, and their flanks : They are always halfway through the grooves, and they are young people such as ih. and 1d. Figures 1b and 1b are generally used when the grooves are so narrow that a trapezoid shape: a: structure :, rr »int: the stability of all of them is especially in gpngteai Ä Ä avoiding edges ek, for example, rounding; vigy with chamfer, improves electric power • magnetic properties. since it has been possible to avoid high-pitched aitii in those places.

The drawback of the known figures is, among other things, that it is too much ?! high magnetic material, such as iron content, can improve the wedge's electrical and magnetic properties, but strongly as ancestors! For example, in the case of layered wedges, the separation of the individual layers occurs, which can lead to a breakdown of each layer and, as a consequence, a motor bursting. Sometimes there are one or more spacers between the coil and the impregnator of the motor or generator for impregnation. resin benedyesft, perfectly. This way, it is not always perfect for curing the cistern, there are also lots of glue-covered areas where the wedge is therefore slightly looser | and the constant mechanical stress due to magnetic load: you can loosen even further, maybe you can move too hard to lay out the pads The current usage pattern! therefore, our goal is to create clues that: at least partially solve the above-mentioned problems,

OPERATING PRINCIPLE OF THE USE SAMPLE The use of this tool to solve the winding of the tarpaulin grooves on the air gap is accomplished by means of locks, which are formed by a straight block where one of the parallel faces of the column is the coil, the other parallel sheet is the air gap wall. where the parallel sheet facing the sample and the coil is provided with a longitudinal longitudinal extension extending towards the coil. Preferably, the parallel face of the closure facing the air gap is also provided with a longitudinal extension:, which extends from the tongue to about Told in this case, is a continuation of the wedge! which is smaller than the maximum width of the wedge, and which extends into the groove or the groove, The maximum width of the wedge corresponds to the maximum distance between the grooves where the particular wedge is inserted.

For a closure, the pattern of use with shingles extends: supplying the wedge against the chafing and stabilizing its position in the groove, which first of all is suitable for the coil on the inner side of the coil, i. E. One side of the wedge, i.e. a. Lignus Filler Handle Extension promotes heat dissipation An inner extension is the servant itself toward the former as a spacer, which makes it unnecessary to use them, especially if more spacers are required. There are no special constraints on the dimensions of the extensions except for the widths that are substantially equivalent to the given groove in the given location, Â The skilled artisan will readily determine the optimum between the cost of producing a sealed closure material for the use pattern and the cost of producing it. conceivable The limit of the heights of the usefulness in the case of an internal pond is the length of the groove of the groove of the groove at the outer extremity: the height of the support. Preferably, the extension is adapted to the particular pattern of groove walls,

In a preferred embodiment, the wedge itself, without the axle (s), is a central axis of the motor or generator shaft into the teeth: the plane of the maximum width is located in the horizontal plane of the closure. Or, at the same height, the locks are seen from the lowest point of view, without the need for an extension. An advantage of this is that it is generally to insert the wedge into the grooves of the motor at the same distance; it is easier to do and the wedge is placed in the groove without tension. For the same reason, the whole lock is preferably designed as such with a central plane, such as a utility top: including a top-side top extension, but the extensions are optionally asymmetrical | They are.

In other preferred embodiments, the usage pattern is taerlni sealed with a pair of extensions, which increases stability, drives the thermal conductivity, and renders production simpler as it is; whole pieces can be made in one piece.

To improve the eieMrames Ä magnetic properties, we need to reduce the amount of field property as described above; the corners of the extension or extension; preferably rounded or broken The use pattern seals preferably have glass fiber reinforcing plastics (GFK), so that conventional materials can also be used to produce the present compositions. # According to the pans! the closures are particularly preferably made of magnetic material, in the form of iron powder for the feedstock. made of filled plastic. Such embodiments have particular advantages, namely that the presence of additional magnetic materials in the groove improves electrical properties, resulting in a lower degree of machine overheating with greater efficiency and less energy loss. The magnetic material also has better thermal conductivity and thus good heat dissipation when applied instead of one or more spacers in the groove, which further reduces the wood heating of the machine, and in addition, the closure according to the usage pattern may be at least partially coated with an insulating material. you can apply the material to the wedge in any way you like, such as spraying, sauce, eosetelis! Insulating material may include all materials known in the art, such as polyethylene felt or wood strips, aramides (e.g., Nomex®), or inorganic material based products (e.g., Teflon # '~ lamlates). In the following, we use m patterns for concrete examples of examples: Write:% which should only be considered as illustrations and not limitations of protection. Here we refer to the appendix »:
