Synchronous motors with cylindrical rotors for the petrochemical industry
An important role is played by the compressor in the petrochemical industry. Typical high-speed compressor drivers are turbines and induction and synchronous motors. The cylindrical-rotor synchronous motor and its application as a high-speed compressor driver is discussed. Important tasks within the production processes of the petrochemical industry include gas liquefaction, compression, refrigeration, and heat recovery. Compressor drive systems constitute important components in plants for such processes. In the past, large high-speed radial and axial compressors were driven mainly by turbines, but in recent years electric motors have been used increasingly. In addition to lower plant costs, the advantages include high operating efficiency, low pollution, and simpler handling and maintenance. The majority of drives are operating at constant speed, using a four- or six-pole motor with step-up gear. For large ratings, synchronous motors are preferred.
