  • Electric drive compressor system
    Patent number: 11867163
    Abstract: An electric drive compressor system (1) comprising: a reciprocating compressor (2) having temperature and pressure sensors (83, 84) for sensing a pressure and temperature of gas prior to compression by the compressor (1) and for sensing a pressure and temperature of gas after compression by the compressor (1); a motor (3) connected to the compressor (1) for driving the compressor (1); a cooling system (4) for cooling the motor (3); and a controller (5) for controlling the motor (3) in real time based on the temperature and pressure sensor readings of the gas prior to and after compression by the compressor (1).
