Rotor spinning machine with a multiple number of work stations and a suction device

A rotor spinning machine, comprising:

• a plurality of work stations arranged side by side between two front-side ends along at least one longitudinal side of the rotor spinning machine;
• each of the work stations comprising work elements for production and winding of a yarn in a spinning process, the work elements comprising a feed device, an opening device, a spinning rotor, and a winding device;
• a suction device that provides a negative spinning pressure at the work stations, the suction device comprising at least two separate negative pressure sources, wherein one of the negative pressure sources is arranged at each of the two front-side ends of the rotor spinning machine;
• each negative pressure source connected to a separate negative pressure channel that extends in a longitudinal direction of the rotor spinning machine only over a part of a total number of the work stations;
• each work station comprising a rotor housing connected to at least one of the separate negative pressure channels to provide negative pressure for the spinning process;
• and
• each work station comprising an individual drive for the spinning rotor.
