Demanding manufacturing environments, such as utility, oil, gas and mining operations rely on medium voltage power to drive large industrial motors – often running 24 hours a day. To meet these needs, Rockwell Automation has announced new enhancements to medium voltage PowerFlex 6000T Variable Frequency Drives (VFDs).
PowerFlex 6000T drives with TotalFORCE technology deliver more than just high-performance motor control. The VFDs deliver real-time operating system data that can help increase productivity and energy savings.
To meet customer demand for greater output frequency range, Rockwell Automation has expanded the PowerFlex 6000T variable frequency drive range up to 120 Hz. The new output frequency range meets the needs for high-speed industrial applications, including turbines, compressors and pumps.
The PowerFlex 6000T motor controller also offers the new RealSine solution. The option helps reduce input harmonics to lower levels than the industry standard. Ranging from 2.4…4.16 kV up to 215 A, each individual secondary winding is specially phase-shifted to achieve 54 or 72 pulse respectively – compared to typical 18 or 24 pulse designs.
The new design offers up to 30% improvement in total harmonic current distortion at the drive primary side. By reducing harmonic distortion, the VFD improves system efficiency, reduces energy cost and minimizes power distribution issues on the factory floor.
When you invest in Rockwell Automation, you join in their mission to improve the standard of living for everyone by making the world more productive and sustainable.
