Definitions

the invention relates to an electrical cable for a linear motor, which consists of an electrically well conductive metallic conductor, one surrounding it inner conductive layer, an insulation arranged above the inner conductive layer, one the outer conductive layer surrounding the insulation, one over the outer conductive layer arranged jacket made of electrically conductive insulating material and a arranged between the outer conductive layer and the jacket, electrically conductive Intermediate layer exists and on a manufactured with such a cable three-phase winding (DE 196 38 603 A1).
Linear motors have long been known for different types of electric drives. There are both direct current and alternating current synchronous and Asynchronous motors.
the linear motor has both a fixed stator and a movable rotor part in contrast to the conventional motor not circular, but arranged in a straight line.
the electrical energy is like this with a linear motor converted into mechanical energy that it is immediately used for a translational movement becomes usable.
Areas of application for a linear motor are, for example Passenger transport, the conveyor and transport system, assembly lines, luggage transport, Mining, cranes, towing equipment, machine tool slides and the Actuation of sliders.
the linear motor can be in the grooves of an inductor have arranged excitation winding, which is three-phase in AC.
the rotor part then either consists of a rail made of electrically good conductivity Material such as copper or aluminum (asynchronous motor), or made of permanent magnetic material (synchronous motor).
the invention has for its object the cable described above or to make the winding so that it or it in a simple manner different operating voltages is adaptable, so that damage by high operating voltages can be excluded.
the electrical resistance of each Length unit can be variably set to values between 1 ⁇ / m and 30 ⁇ / m.
the resistance value of the intermediate layer per unit length is greater than the corresponding one Resistance value of an earth conductor attached to the sheaths of the cables.
the electrical resistance of the shield to the respective Requirements can be easily adapted.
the structure of the cable be Manufacturing processes and the equipment used for this can be used remain unchanged.
the tape can, for example be designed as a hybrid tape with plastic threads and metallic wires or made of consist of carbon fibers combined into one unit.
the resistance value of the However, the screen remains so high that no low-resistance leads to high losses Secondary circles arise. Losses due to voltages and currents in the cable shield are negligible compared to other line losses.
the Resistance value of the band is set so that it is for the respective Use of the cable is sufficiently high. If in the stator of the linear motor, in the the cable is used for the three winding strands, a separate one with the conductive ones Sheaths of all three cables in good contact with the earth conductor are present the resistance value of the tape is higher than the resistance value of one as an earth conductor used metallic strand set. Regardless of that for the Operating voltage used for linear motors are then fault and equalizing currents safely derived via the earth conductor. The cable and especially its outer sheath are effectively protected against damage caused by excessive currents. This is also true with large temperature differences, which the cables operate during the day and night and are exposed in different seasons. The tape stays with the Manufacturing set resistance value even then with great accuracy.
the inductor of a linear motor is designated, which together with a three-phase winding forms the stator of the same.
the inductor 1 consists of Laminated core, in which slots 2 for receiving winding strands of the winding are attached.
the stator is elongated. It can be many kilometers long.
winding strands consist of electrical cables whose more precise structure is shown, for example, in FIG. 2.
a cable 3 is shown, the meandering course in the grooves 2nd of the inductor 1 is attached.
the unoccupied grooves 2 of the inductor 1 are for Inclusion of two additional cables with the same structure as cable 3 intended. For the sake of simplicity, they are not shown.
the three cables together form the three-phase winding of the linear motor.
the cable 3 is like this built that it is easy to deform to the meandering course and without additional effort its shape also in the outside of the inductor 1 Areas - the winding heads 4 - maintained.
a metallic strand 5 serving as an earth conductor can extend over its entire length electrically well conductive material that is in good electrical contact with the Cable stands and can be connected to earth potential.
the cable 3 has, for example, the following Construction:
the conductor of the cable 3 is designed as a conductor rope 6, which consists of a variety of Single wires is formed. There are at least two layers of individual wires. The direction of lay of the stranding in these two layers should be opposite. For in the event that there are more than two layers, they should alternate have the opposite direction of impact.
the conductor rope 6 can There are aluminum wires. But it could also be copper wires or wires an aluminum-copper composite can be used.
the conductor cable 6 is surrounded by an inner conductor layer 7, which is on the same can be extruded.
the extrusion process is coordinated so that the Material of the conductive layer 7 also penetrates into the gusset, which between the Individual wires of the outer layer of the conductor cable 6 are present.
the conductive layer 7 is thereby firmly connected to the conductor cable 6, since it is anchored to the same.
the Tight fit is so good that the conductive layer 7 neither by bending nor by axial Stress is released from the conductor rope 6.
the inner conductive layer 7 can preferably one based on EPDM (ethylene propylene diene monomer) constructed material can be used. This is a material based on one Copolymers of ethylene and propylene.
the base material becomes highly active lead blacks added. That can be a soot alone. There can also be several guide blacks in the Waste is used.
Insulation 8 is arranged above the inner conductive layer 7 and is in the same Operation can also be applied by extrusion.
the insulation 8 consists for example of a mixture based on EPR (ethylene propylene rubber).
An outer conductive layer 9 can also be applied to the same operation Insulation 8 are extruded for the same material as for the inner Conductive layer 7 can be used.
the cable 3 has an outer jacket 10 which is made of a conductive Plastic is made. It is also applied by extrusion.
materials for the Sheath 10 are suitable, for example, polymers based on acetate copolymers of ethylene, which have, for example, an acetate content of 30% to 70%. This Highly conductive carbon blacks are added to polymers, preferably in combination
the intermediate layer 11 consists of a band H (FIGS. 3 to 8).
it can be a hybrid tape in which plastic threads and metallic ones Wires of variable composition are connected to one unit.
the electric one Resistance per unit length of such a hybrid band can be changed as a result. He can within the specified limits in the production of the hybrid tape, for example, using the so-called Raschel technology, and thus the respective requirements can be easily adapted.
materials for the Plastic threads are, for example, polyamide, polyaramide or glass.
the metallic wires are preferably made of copper.
the hybrid band can be in any width and length can be produced. The width can be for use in cables for example between 10 mm and 150 mm. The same benefits apply to one Band consisting of carbon fibers combined in one unit.
the desired value for the electrical resistance of the band H is the manufacturer same specified by the manufacturer of the cable.
the band H supplied by the manufacturer then has the value required for its intended use between 1 ⁇ / m and 30 ⁇ / m.
the manufacturer of tape H has different options. So can be used to adapt the electrical resistance of a hybrid band to the given values the number of metallic wires versus the number of Plastic threads can be variable. The can also be varied Diameter of the metallic wires.
the metallic wires can be on a predetermined length of the hybrid band also electrically either in series or are parallel to each other. You can also alternate both in series and be arranged parallel to each other.
the band H can form the intermediate layer 11 either around the outer Guide layer 9 are wrapped around or formed in the longitudinal direction, as in 3 to 8 is shown:
the band H is around the outer conductive layer 9 of the cable 3 wrapped around so that its edges overlap.
the overlap Ü can for example between 2 mm and 8 mm.
the band H itself can be used as Wrapping tape should be 10 mm to 80 mm wide.
the band H can also be wound around the outer conductive layer 9 in this way be that its edges meet. This results in a sales-free, all-round and closed intermediate layer 11 in the longitudinal direction of the cable.
An uninterrupted intermediate layer 11 is also provided when the tape H 5 with a gap L between its edges around the outer conductive layer 9 is wrapped around.
the cable is used with particular advantage in the stator of a linear motor in which at least one metallic strand 5 serving as an earth conductor made of good electrical power conductive material is present.
the strand 5 has good electrical contact with the conductive sheaths 10 of the three cables present in the stator. High, for example Currents generated by induction are usually higher than those on earth connected strand 5 dissipated. That is in any case with the present cable ensured because the value of the electrical resistance of the intermediate layer 11 used tape H per unit length at least slightly higher than that corresponding resistance value of the strand 5.
