US 10,207,695 B2 · Compressor system and method for operating the compressor system in dependence on the operating state of the rail vehicle

Abstract

A rail vehicle compressor system comprises a compressor, driven by an electrical machine via a drive shaft, for producing compressed air for at least one compressed air tank. The electrical machine is activated at least indirectly via a control device for operating the electrical machine at least one nominal speed between a maximum speed and a minimum speed. At least one pressure sensor determines the pressure for the control device and is disposed in a compressed-air-carrying line downstream of the compressor. A final control element for continuously influencing the speed of the electrical machine is disposed between an electrical supply and the electrical machine, wherein the control device controls activation of the final control element. A method for controlling the compressor system is also provided, wherein, the compressor is operated at a variable speed in between the maximum speed and the minimum speed based on rail vehicle operating state.
