Users in heavy industries have a new motor control option for compressors, pumps and fans. Allen-Bradley PowerFlex 6000 medium voltage AC drives from Rockwell Automation offer expanded, user-friendly control for variable and constant torque applications. The latest release delivers a wider voltage range (2,4 to 11 kV) and provides 100 percent starting torque, leveraging sensorless vector control.
The drives are easy to commission, use and maintain, with standard faceplates and EtherNet/IP connectivity. They provide a cost-effective solution for heavy industries with higher power needs in their applications.
“Our scalable portfolio of medium voltage drives offers a breadth of functionalities to best fit application needs,” said Rikus Botha, PCB sales manager, Rockwell Automation sub-Saharan Africa. “Together with the PowerFlex 7000 drive, users can now select the right feature set for their application requirements.”
With an extended power range, the drive can be used for applications with output voltage ratings up to 11 kV and motor current ratings up to 680 A, while remaining an air cooled design. With eco-designed main cooling fans, users in Europe and other IEC markets can meet EC regulation 327 and ErP directive 2009, and avoid the larger footprint of a liquid-cooled drive. Internally powered cooling fans reduce power requirements and installation costs. A tertiary winding on the isolation transformer provides internal power for the fans.
Two new ratings are available – 6,9 kV for North America, and 11 kV for EMEA and Australia. The full range of ratings includes 2.4, 3, 3.3, 4.16, 6, 6.3, 6.6, 6.9, 10 and 11 kV.
With optional, automatic cell bypass up to 680 A, users can keep their operations running in case of a power cell failure and reduce unplanned downtime. In addition, an uninterruptible power supply helps increase system reliability, minimise downtime and mitigate potential machine damage.
