A rotary vane pump for generating a vacuum, having an electric drive with a motor stator and a motor rotor, wherein the motor stator and the motor rotor radially encompass the pump housing. The motor stator is non-rotatably disposed around or on the pump housing. The motor rotor is disposed on the side of the motor stator facing away from the pump housing, such that an overall housing is provided that accommodates the electric drive and the pump housing, and the overall housing has a housing floor and a housing shell, wherein the housing floor, together with the pump housing delimits the pump chamber. |

1. A rotary vane pump for generating a vacuum, having a pump housing that delimits a pump chamber, having a pump rotor that can rotate in the pump housing, and having at least one vane in the pump rotor, supported such that it can be radially displaced, for dividing the pump chamber, wherein an electric drive is provided for driving the pump rotor, wherein the electric drive has a motor stator and a motor rotor, wherein the motor stator and the motor rotor radially encompass the pump housing, wherein the motor stator is non-rotatably disposed around or on the pump housing, and the motor rotor is disposed on the side of the motor stator facing away from the pump housing, wherein an overall housing is provided, which accommodates the electric drive and the pump housing, and the overall housing has a housing floor and a housing shell, wherein the housing floor, together with the pump housing, delimits the pump chamber. |
