To meet customer demand for greater output frequency range, Rockwell Automation expands the PowerFlex 6000T variable frequency drive range up to 120 Hz. The new output frequency range meets the needs ...

Do you know how to maintain variable frequency drives (vfd’s)? Doing so is easier than you might think. By integrating some simple, logical steps into your preventative maintenance (PM) program, you ...

Early VFDs affected output voltage control through controlled rectification and the DC bus was variable, but the VFD output waveform was somewhat crude. Since the early 1990s, digital control of ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...
