Problems solved by technology

This means that basically the same structure as in German patent DE 297 13723, the magnetic lines of force form flux leakage due to the air gap to be overcome, which causes a large power loss
[0006] The disadvantage of such a device is that only low power densities can be achieved with this known design

Embodiment Construction

[0029] In FIGS. 1 and 2 , the rotor is designated by 1 and the stator housing, which receives the rotor, is designated by 10 . The rotor 1 comprises magnets 2 on its surface, ie on both sides thereof, whose polarity is opposite. This means that the magnets on one side of the rotor face are north poles and the magnets on the opposite side are south poles. The magnet 2 is distributed into two turns on the rotor. Furthermore, the rotor itself comprises a radial rim area 5 not equipped with these magnets and having two holes 3 for passing the skeins. In order to reduce wear, ceramic inserts 4 can be arranged on the two bores 3 .

[0030] The rotor 1 is housed in the stator housing 10 . The stator housing, generally indicated at 10, comprises a C-shaped iron core 11 around which is wound a corresponding winding 12, the ends of which face towards the magnets of the rotor. Between the rotor and the housing or between the rotor and the core is a gap 20 through which the skeins 30,...

Abstract

The invention relates to a device for forming a doup edge. The device has an electromotor, comprising a rotor and a stator for accommodating the rotor, the rotor (1) having at least two guide openings for the doup threads and having several axially oriented magnetic poles (2). The rotor can be held by the stator (10) in an axial direction on both sides.

Description

technical field [0001] The invention relates to a device for forming a leno selvedge (Dreherkante) with an electric motor comprising a rotor and a stator receiving the rotor, the rotor having at least two skein guide holes, the rotor also having a plurality of shafts oriented magnetic poles. Background technique [0002] EP 674031 discloses a so-called rotary selvedge twister for weaving machines, which has a ring designed as a rotor which is accommodated in a housing designed as a stator. The ring, also called a disk, has two guide holes for the passage of the skeins. Furthermore, such rings of the prior art are arranged radially, ie on their outer periphery, with magnets which cooperate with the stack of steel laminations arranged in the stator housing. Through the rotation of the rotor in the casing, the skeined yarns introduced into the two yarn guide holes by the rotor are twisted with each other, and each twisting forms a weft yarn. The mode of operation of forming ...
