Embodiment Construction

[0015] figure 1 Shown are known poles, which are used, for example, in magnet arrangements for carrying magnets in maglev trains. The pole comprises a ferromagnetic iron core 1 consisting of a plurality of silicon steel sheets, which is provided with a pole face 2 on the top side, a contact face 3 for the magnet back 4 on the bottom side, and an upper The peripheral surface 5 provided between the pole surface 2 and the contact surface 3 below. On the peripheral surface 5 , a winding 6 is wound in the form of a disc, which is formed, for example, of conducting strips arranged in multiple layers, the conducting strips being made of aluminum or another suitable material with good electrical conductivity. exist figure 1 An intermediate layer 7 of insulating material, for example a suitable plastic, which is shown only in the right part but actually surrounds the core 1, is arranged between the core 1 and the winding 6 and serves in particular for the winding 6 to lie opposite th...

Abstract

The invention relates to a magnet pole for magnetic levitation vehicles, containing an iron core (1), a coil (6) applied thereon, a rear (4) of a magnet lying against a lower contact surface (3) of the iron core (1), and a protective layer (9) that encases the coil (6) and an upper pole surface (2) of the iron core (1). The protective layer (9) has a section (15) made of an elastic material in a lower region of the iron core (1), said section bordering the circumferential surface (5) of the iron core.

Description

technical field [0001] The invention relates to a magnetic pole of the type stated in the preamble of claim 1 and to a method for its manufacture. Background technique [0002] Magnetic poles of the above-mentioned type are used in maglev trains and here, for example, in magnet arrangements carrying magnets. It essentially comprises an iron core and a winding in the form of a strip of aluminum or the like wound onto the peripheral surface of the iron core (eg DE 197 03 497 A1, DE 10 2004 011 941 A1). In order to protect against environmental influences, such as moisture, the poles are also encapsulated with a protective layer of plastic, such as epoxy resin, which is relatively hard, wear-resistant and inflexible, and serves as protection from corrosion and mechanical loads. [0003] The underside of the core generally has no protective layer. The main reason for this is the fact that the undersides of the poles of a magnet arrangement are usually connected to one another...
