The simplified design of this drive lowers commissioning, training and maintenance time, and significantly reduces the total cost of ownership from initial purchase price to annual maintenance costs.
Rockwell Automation now offers the Allen-Bradley Powerflex 7000 medium voltage AC drive. The drive offers users enhanced reliability and ease of use. Part of the new Allen-Bradley Powerflex family of drives, it incorporates a new power semiconductor device known as the symmetrical gate commutated thyristor (SGCT). These SGCT components exhibit lower conduction and switching losses, reduce total component count and increase reliability. The Powerflex 7000 also features sensorless vector control for better performance compared to 'volts-per-hertz' drives and it has the ability to control motor torque similar to DC drives. The drive meets IEEE-519 harmonic guidelines (without a phase-shifting transformer), maintains near unity power factor and produces sinusoidal voltage and current waveforms to the motor. (Inverter-duty motors are not required with this drive.)
The air-cooled Powerflex 7000 features a user-friendly operator interface similar to all Powerflex drives and is available in standard supply voltages from 2400 to 6600 V to control induction and synchronous motors ranging from 373 kW (500 hp) to 3000 kW (4000 hp). This wide range makes the Powerflex 7000 ideal for standard and special purpose industrial and commercial applications ranging from fans, pumps and compressors, to extruders and conveyors.
Rockwell Automation says that its Allen-Bradley Powerflex family of drives represents the industry's latest in drives design and performance, from low to 3000 kW (4000-hp) applications. New capabilities in motor and logic control have shaped drives into more than simple motor control devices, which equates to greater productivity for users. Powerflex drives are smarter than ever, with the ability to affect motor performance and communicate with the control process, enabling users to more simply manage information from shop floor to top floor.
