Rockwell Automation Releases Medium Voltage Drives With Sensorless Vector Control
Heavy-industry operators can now use the Allen-Bradley PowerFlex 6000 medium voltage drives to meet a broader range of application requirements. Rockwell Automation has enhanced the drives to offer sensorless vector control (SVC) for 0-200-amp applications, additional voltage ratings and a standard-efficiency transformer option for the Asia-Pacific market. 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 addition 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.
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.
