Rockwell Automation has released enhanced Allen-Bradley PowerFlex 6000 medium voltage drives that offer sensorless vector control (SVC) for 0-200-amp applications, additional voltage ratings and a standard-efficiency transformer option for the Asia-Pacific market. These enhanced drives are focused on heavy-industry operators that can apply them to a broader range of application requirements and help to lower their total system costs. With a previous launch for 200-680-amp applications in 2017, SVC is now available for 0-680 amps and 2.3-11 kV voltage ratings.
The SVC enhancement brings heavy-duty ratings to PowerFlex 6000 drives in the 0-200-amp range, already available for the 200-amp and above range. It provides constant torque capability without the need for an encoder, which can help to lower the total cost of ownership for applications, such as slurry pumps and reciprocating compressors.
Two new voltage ratings are also now available for the 0-680-amp drive range. The first is 6.9kV, most commonly found in Canada, and the second is 11 kV, most commonly found in Australia and Europe.
In addition, a standard-efficiency transformer option is now available for the Asia-Pacific market, which can also help to lower the total cost of ownership for the drives.
