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). Features and advantages of the systems (1) as exemplified are as follows: lightweight and compact design; refrigerant circuit sealed from electric motor for ease of maintenance and service; air cooled from unique fin and airflow passage design, with fan width pulse width modulation; intelligent control system with pressure and temperature sensors/transducers and software; separate compressor working assembly to ensure piston alignment and compression is not affected by heat distortion; separate outer housing and compressor crankcase to ensure leak free operation.
