Abstract (en)

[origin: CN110777454A] The invention relates to an open-end rotor spinning device (3) with a spinning rotor (19) which can be driven by an individual electromotive drive (21), the rotor cup (17) of the spinning rotor rotates in a rotor housing (10) which is closed by a cover element (22) during the spinning process and is connected to a negative pressure source (23) via a pneumatic line (29). According to the invention,at least one pneumatic line (29) arranged between the rotor housing (10) and the negative pressure source (23) is positioned in the area of the individual electromotive drive (21) of the spinning rotor (19) in such a way that the spinning negative pressure initiated by the negative pressure source (23) cools the individual electromotive drive (21) of the spinning rotor (19) via a suction air flowpresent in the pneumatic line (29).
