Abstract

The levitation system consists of pairs of three limb choke coils with the cores vertically side-by-side and connected such that the centre limb carries the sum of the flux in the two equal outer limbs. The secondary winding, forming part of the vehicle to be propelled and stabilised, covers, at least in part, all of the six magnetic poles thus created. Instead of aluminium the use of a higher conductivity material for the secondary winding on the vehicles is proposed, and the use of copper of copper alloys suggested. With copper the levitation height is practically doubled for the same primary circuit field strength. Thus for no increase in levitation the primary circuit input can be significantly reduced.

Description

Bezeichnung: Wechselstrommagnetanordnung zur ErzeugungDesignation: AC magnet arrangement for generation

eine Schwebelage stabilisierender Abstoßungskräfte für Körper aus nichtferromagnetischem Werkstoff Die Erfindung betrifft eine Wechselstrommagnetanordnung zur Erzeugung eine Schwebelage stabilisierender Abstoßungskräfte für Körper aus nichtferromagnetischem Werkstoff, bei dem von einem Wechselstrom in entgegengesetzter Richtung durchflossene einseitig offene Dreischenkel-Drosselspulen mit ihren Längsseiten nebeneinanderstehen, bei dem deren Wicklungen so parallel oder in Reihe geschaltet sind, daß jeweils der Fluß im mittleren Schenkel einer Dreischenkel-Drosselspule die Summe der Flüsse in den äußeren Schenkeln darstellt und bei dem der Körper die von den Dreischenkel-Drosselspulen gebildeten 6 Magnetpole wenigstens zum Teil überdeckt. a floating layer of stabilizing repulsive forces for the body non-ferromagnetic material The invention relates to an alternating current magnet assembly to generate a floating layer of stabilizing repulsive forces for bodies non-ferromagnetic material, in which from an alternating current in opposite Direction through which three-legged choke coils open on one side with their long sides stand next to each other, in which their windings are connected in parallel or in series are that in each case the flux in the middle leg of a three-legged choke coil represents the sum of the flows in the outer thighs and at which the body the 6 magnetic poles formed by the three-legged choke coils are at least partially covered.

Eine derartige Wechselstrommagnetanordnung ist Gegenstand der aus der DE-OS 21 08 305 bekannten Hauptanmeldung und der aus der DE-OS 24 22 083 bekannten Zusatzanmeldung.Such an alternating current magnet arrangement is the subject of from the main application known from DE-OS 21 08 305 and the one known from DE-OS 24 22 083 Additional registration.

Es hat sich durch praktische Versuche herausgestellt, daß nichtferromagnetische Werkstoffe hoher elektrischer Leitfähigkeit als Werkstoff für Schwebefahrzeuge geeigneter sind als Aluminium. Besteht der Fahrzeugboden mit seinen Seitenkanten beispielsweise aus Kupfer statt aus Aluminium, so steigt bei gleicher Feldstärke der Primärmagnete auf der Fahrbahn die Schwebehöhe auf das Doppelte. Der im Kupfer induzierte Sekundärstrom erhöht sich gegenüber dem im Aluminium im umgekehrten Verhältnis zu den spezifischen Widerständen der beiden Metalle.It has been found through practical tests that non-ferromagnetic Materials with high electrical conductivity are more suitable as materials for suspension vehicles are as aluminum. If the vehicle floor exists with its side edges, for example made of copper instead of aluminum, the primary magnet increases with the same field strength on the road the hovering height doubled. The secondary current induced in the copper increases compared to that in aluminum in inverse proportion to the specific Resistances of the two metals.

Es ist ICu RAl IAl RCu Darin bedeuten ICu und IA1 die induzierten Ströme im Kupfer bzw. Aluminium und RAl und RCu die spezifischen Widerstände der beiden Metalle. It is ICu RAl IAl RCu where ICu and IA1 mean the induced Currents in copper or aluminum and RAl and RCu the specific resistances of the both metals.

Gleichung (1) setzt voraus, daß die im Kupfer und Aluminium induzierte Spannung die gleiche ist. Das ist bei der durch den erhöhten Wirbelstrom bei Kupfer hervorgerufenen größeren Schwebehöhe der Fall.Equation (1) assumes that the induced in copper and aluminum Tension is the same. This is due to the increased eddy current in copper caused greater floating height is the case.

Der größere Sekundärstrom erhöht Antriebskraft und seitliche Stabil sierungskraft, aber auch die Verluste im Verhältnis RAl/Rcu.The larger secondary current increases driving power and lateral stability sizing power, but also the losses in the ratio RAl / Rcu.

Infolgedessen ist es möglich, die Primärleistung der Fahrbahn,Zmagnete ebenfalls im Verhältnis RCUlRAl herabzusetzen, um die gleichen Betriebsverhältnisse wie beim Aluminium zu erhalten. Das be text eine Ersparnis an Investitions- und Betriebskosten, die etwa im gleichen Verhältnis liegen. Lediglich die Verluste im Fahrzeug bleiben die gleichen, sind aber gegenüber denen auf der Fahrbahn klein. Die Kühlung erfolgt teils durch den Fahrwind, teils durch eine Kühlanlage, die von Sekundärwicklungen im Boden des Fahrzeugs gespeist wird.As a result, it is possible to use the primary power of the roadway, Zmagnete also reduce in the ratio RCUlRAl to the same operating conditions as with aluminum. That be text a saving in investment and Operating costs that are roughly in the same proportion. Only the losses in Vehicles remain the same, but are small compared to those on the road. The cooling is done partly by the wind, partly by a cooling system that is supplied by Secondary windings in the bottom of the vehicle is fed.
