Abstract

The invention relates to a compressor system for a rail vehicle, comprising a compressor (3), driven by an electrical machine (1) via a drive shaft (2), for producing compressed air for at least one compressed air tank (4), wherein the electrical machine (1) can be activated at least indirectly via a control device (5) for operating the electrical machine (1) at at least one nominal speed (n) between a maximum speed (m) and a minimum speed (i), wherein furthermore at least one pressure sensor (7) for determining the pressure for the control device (5) is disposed in a compressed-air-carrying line (6) downstream of the compressor (3). According to the invention, a final control element (8) for continuously influencing the speed of the electrical machine (1) is disposed between an electrical supply (15) and the electrical machine (1), wherein the activation of the final control element (8) takes place via the control device (5). Furthermore, the invention also relates to a method for controlling the compressor system according to the invention, wherein, in dependence on an operating state of the rail vehicle, the compressor (3) is operated at a variable speed, assuming any intermediate value between the maximum speed (m) and the minimum speed (i).

Description

technical field

[0001] The invention relates to a compressor system for a rail vehicle comprising a compressor driven by an electric motor via a drive shaft for generating compressed air of at least one compressed air container, wherein the electric motor can at least indirectly Actuated by a regulating device for operating the electric machine at at least one setpoint speed between a maximum and a minimum speed, in addition at least one device for measuring pressure sensor. Furthermore, the invention also relates to a method for controlling the compressor system of the invention. Background technique

[0002] Compressors in rail vehicles place many, partly opposing demands, such as high supply performance, sufficient on-duration, low noise emissions, low energy consumption, small installation space and low acquisition costs and Life cycle costs. Here, depending on the operating state of the rail vehicle, the compressor has to meet very different demand profiles. A typic...
