WEG motor-control packages comprise low-maintenance motors, ruggedised CFW-09 inverter drives and direct-on-line (DOL) starting controls. These packages are helping En-Fab to achieve production targets in a major steam-injection recovery project undertaken to help Petroleum Development Oman (PDO) reverse Oman's declining oil production. En-Fab was contracted by PDO to design and install 100-million-BTU steam generators in the Omani oil field.To date, WEG has delivered 34 motor-control systems to En-Fab to control multiple motors on the oilfield. Each system comprises WEG's CFW-09 Series variable frequency (VF) drives and customised control packages with direct-on-line (DOL) starting. This equipment helps run the main and booster pumps that supply water to the steam generators, as well as the large fans for combustion air to the burner assembly. En-Fab has requested other equipment vendors to supply two- and four-pole WEG motors on their equipment to complement the use of the WEG VF drives and controls.
'It's the ruggedness and the ability to operate at differing voltages and frequencies that has ensured the specification of WEG products for this project,' said Michael Smith, WEG's automation sales engineer. 'The WEG CFW-09 series of VF drives features Vectrue Technology and is among the world's most advanced technology for use with three-phase AC induction motors. He added: 'The series provides users with the benefits of software selectable V/F, sensorless vector and closed-loop vector (with encoder) control techniques in one product.
