Embodiment Construction

[0012] according to figure 1 A pole of the type to be referred to below comprises a core 301 formed from a group of metal sheets, preferably square and with trimmed corners, and a winding 302 applied thereto. The manufacture of the core can utilize many different methods, which are not essential to the invention. In addition, said core 301 may be provided with an annular winding carrier 303 arranged close to its shell surface, said winding carrier being made of an insulating material such as plastic and having assembly flanges 304 between which the windings 302 will be located. The winding carrier 303 thus serves both for the mounting of the winding 302 and for the electrical insulation of the winding 302 relative to the core 301 in the radial direction with respect to the center of the core 301 and the winding axis 305 .

[0013] Said winding 302 consists, for example, of alternating layers of conductor strips 306 (for example made of aluminum) and first insulating layers 30...

Abstract

Disclosed is a magnetic pole for magnetic levitation vehicles, comprising a core (301) and a winding (314). According to the invention, the winding (314) contains at least two disks (315, 316) consisting of conduction bands which are wound around the core (301) in several layers. The individual layers are electrically insulated radially in relation to each other and in relation to the core (301) by means of first insulating layers (303, 310, 321). The individual disks (315, 316), however, are electrically insulated axially in relation to each other by means of at least one second insulating layer (317).

Description

technical field [0001] The invention relates to a magnetic pole according to the preamble of claim 1 . Background technique [0002] This type of poles is used in magnetically levitated vehicles for different purposes, for example, as a load bearing, part of a guide or as a braking magnet. These poles have hitherto been made from a core and applied to it a winding formed from layers of insulator and conductor arranged in an alternating sequence (PCT WO 97 / 30504). Conductors and insulators are made of strip materials such as aluminum tape and thin insulating foils. [0003] Prior art poles consist of a disc, so the number of layers is equal to the number of windings. If the number of windings is high, then this arrangement will involve cooling issues. If the core also acts as a cooling component, the heat generated in each layer also needs to pass radially through the electrically required but thermally disturbing insulating foil, whose total thermal resistance increases s...
