Abstract

A spinning apparatus of a rotor spinning machine. The apparatus has spinning shells (2) with openings at two sides are coaxially mounted on a radial electromangeitc bearing, an electromagnetic bearing and an electromagnetic functional unit (31) of an electrical rotation drive of a driving system (3), the spinning shell (2) is provided with an inlet opening for entry of dissolved fibers (4) and an outlet opening for discharging a spun yarn (5), the outlet opening extends to an aperture formed in a stator (33) of the electrical rotation drive, a discharge chute (7) of the yarn is connected to the aperture in the stator of the electrical rotation drive, and the stator of the electrical rotation drive is supported in a cover (11) of a spinning unit (1). A discharge chute is supported in a bushing (6) made of heat conducting material, and the bushing is supported in the stator of the electrical rotation drive and in the cover of the spinning unit and used for dissipating heat from the stator of the electrical rotation drive to the cover of the spinning unit.

Description

technical field [0001] The invention relates to an open-end spinning machine, the spinning rotor of which is coaxially installed on the radial electromagnetic bearing, the electromagnetic bearing and the electromagnetic functional part of the electric rotary driver of the drive system, and is formed by openings on both sides. The yarn rotor is provided with an inlet hole for the entrance of the picked fibers and an outlet hole for the exit of the spun yarn, which continues into a hole formed in the stator of the electric rotary drive, wherein the stator of the electric rotary drive The holes in the yarn are connected by the pulling nozzle of the yarn, and the stator of the electric rotary drive is installed in the cover of the spinning unit. Background technique [0002] An open-end spinning machine in which the spinning rotor is coaxially mounted on radial electromagnetic bearings and electromagnetic functional parts of the electromagnetic bearing and the electric rotary dr...
