Stator stack for long-stator linear electric motor and method for manufacturing same

专利摘要:
A lamination bundle or stack for a long-stator-linear motor. Each lamination is made of a thin, siliconized metal sheet for the electrical industry with a thickness of between 0.35 to 1.00 mm, and at one end of its narrow side has a recess, and at its opposite end has an extension corresponding to this recess for a positive or form-locking arrangement of the bundles in rows adjacent to each other. Of the teeth laterally defining the grooves of cable windings each end tooth has a width which corresponds to half the width of the adjacent tooth and at its free end is cut at an incline, whereby the inclined cutting line extends from the groove to the end of the narrow side. The laminations are stacked so as to completely cover each other, and have their contacting surfaces glued together over the entire surface area thereof.

Tape 19 cutouts are made to accommodate the connecting element and cutouts 24 to compensate for the bends produced when the surfaces of the plate are cut down, touching the surfaces are glued to each other with a pre-cured Duroplast glue. 5-8 microns thick. coated on all sides with an anti-corrosion protective layer - cured
The invention relates to the construction of a plate stator pack for a long-linear linear electric motor, preferably a magnetic railway with a long stator, and to the technology of its continuous manufacture. .
The purpose of the invention is to increase efficiency and improve the performance of the electric motor.
FIG. 1 shows a plant for the continuous production of stator bags; in fig. 2 - three-phase cable winding in the form of a meander; in fig. 3 - plate plate; in fig. 4 - the final segment of the plate package with the applied pre-cured adhesive; in fig. 5 - stacked stator packs; in fig. 6 shows a cut-out of a laminated plate-shaped sheet metal bag with an anti-corrosive overlaying; in fig. 7 - plate stator package.
The manufacturing process of the stator pack is carried out as follows.
In the installation (Fig. 1), the strip 2 of electrical steel is wound from the drum 1 and with the help of a straightening and feeding device 3, the strip is automatically fed to a cutting press 4. -The strip 2 of silicon electrical steel has a thickness of 0.35-1.00 mm and on both sides it is covered: with layer 5 of pre-hardened Duroplast glue. The width of the strip corresponds approximately to the length of the package to be manufactured. In the cutting press 4, plates 6 are cut out of the strip, which, after cutting, with a falling compound of epoxy resin, which is applied by an electrostatic varnishing method. Duroplast glue is applied to the strip on both sides before shtampovka, and before heat treatment in a tunnel kiln or induction heating the plate is glued. After heat treatment, the package is covered with an anti-corrosion protective layer. 2 s, p. and 4 hp f-ly, 7 ill.
give to the store 7 located below the cutting plane, in which they are either counted or weighed, aligned with the position and stacked on each other to form a package 8. Combining tool 9 serves to cut the plates, and it produces both further advancement of electrical steel strip as well as and cutting of special low-waste plates in successive mills with cutting places shifted in a staggered manner.
The bag 8, consisting of superimposed plates 6, with the help of the conveyor 10 is fed first through the curing zone 11 and then through the cooling zone 1-2. When heated to approximately 230 ° C, the individual adhesive-coated plates are glued together under pressure in the store 7 to form the bag 8. At the end of the conveyor 10 and after the cooling zone 12, the laminated glued stator bag 8 is removed from the magazine 7 using the device 13, convenient for post-processing, and laid onto the next conveyor 14. Being on this
The conveyor plate pack is brought to the device 15, in which an anti-corrosion protection is applied to the whole package by an electrostatic varnishing method; the coating 16 is a 5-fold epoxy resin curing compound. The temperature remaining in the package is in the order of 100 ° C and is used to cure the anti-corrosion coating from
0 epoxy resin. The required high bond strength of the plates in the package with glue is achieved by briefly heating the bag in zone 11.
Due to the use of an already pre-cured adhesive for joining the plastic
equal to half the width of the adjacent tooth, and their heads are beveled to the front side. Due to the bevel, the engagement of the carrying magnet and the plate pack of the long stator is prevented during mechanical forced driving. In the package, on the side of the grooves, T-shaped notches 23 are made to accommodate the connecting element in the adjacent plate package. Moreover, on the same side of the plate, notches 24 are made to compensate for the bends resulting from cutting the grooves 17 in the plates.

Tin requires little energy. In this way, the curing time and the continuity of the cutting and piling processes are ensured, so that no additional manufacturing time is required for these operations. Due to the coating of electrical steel with thermosetting adhesive having the property of lubrication, the service life J5 of the tool 9 is extended. Due to the chess cutting, the cut profiles for the grooves of one plate correspond to the teeth of the sheet being cut down and the minimum of electrical waste turn, provides a significant reduction in cost.
Each plate 6 for assembly into a package 8 has grooves 17 on one longitudinal station 25 along the plate on one side in the pore to accommodate the cable-regular sequence and the windings and the tooth 18, which are alternately and equally spaced from each other. the other, and on the other, opposite side, a recess 19 for the slander on the carrier path. In addition, for connecting adjacent packages, groove 20 is made on one end side of each plate, and on the other side there is a corresponding notch, step 21.
Thus, the end sides of each plate package are provided with either a groove or a protrusion, which allow a firm connection of the individual laminated bags placed in the path and the distribution of forces in case of a possible transfer of the carrying magnet from one stator package to another.
In addition, due to the output of
The edge of the glue plates prevents the electromagnetically undesirable contact of the burr of punching of adjacent plates and eliminates shrinkage holes-50 either in a plate-like stator bag with mechanical forces or vibrations. In order to eliminate damage during operation at the joining points of two adjacent lamellar packages 8, the plate is covered, previously deflated, and provide the correct thickness of the grooves between the grooves with the distorted duroscopic glue, and each end plate 22 of each plate 6 is wide.
