Method and system for generating compressed air of at least one vehicle, particularly at least one railway vehicle

A system for generating compressed air of at least one vehicle,

• particularly at least one railway vehicle, comprising:
• an electric motor arranged to generate a driving torque;
• a first coupling means, arranged to selectively assume a first state in which it connects said electric motor to said first compressor or a second state in which it disconnects said electric motor from said first compressor;
• a second coupling means, arranged to selectively assume a first state in which it connects said electric motor to said second compressor or a second state in which it disconnects said electric motor from said second compressor;
• a control means arranged to control the transition between the first state and the second state, and vice versa, of said first coupling means and the transition between the first state and the second state, and vice versa, of said second coupling means, so that said driving torque generated by said electric motor is selectively supplied to the first compressor or to the second compressor or simultaneously to said first compressor and to said second compressor.
