Embodiment Construction
[0031] figure 1 The shown open-end rotor spinning device generally bears the reference numeral 1 and, as usual, has a rotor housing 2 in which a rotor body 26 of a spinning rotor 3 rotates at high rotational speeds.
[0032] The spinning rotor 3 is now driven by an electric motor independent drive, preferably a DC motor 18 , and is mounted with its rotor shaft 4 in the magnetic bearing arrangement 5 . The DC motor 18 is supplied with electrical energy via a line 27 .
[0033] As is known, the rotor housing 2 itself, which is open to the front, is closed during the spinning operation by means of a rotatably mounted cover 8 and is connected to a vacuum source 11 via a corresponding suction line 10, the vacuum The source generates the spinning vacuum required in the rotor housing 2 for yarn production. As can be seen, a channel plate connection 12 is provided in the recess of the cover part 8 , which has a thread delivery nozzle 13 and an opening region of a fiber guide channel...
