VFDs Improve Process Control and Reduce Energy Costs
According to the American Iron and Steel Institute, energy costs account for 20% of the cost of producing steel. So, by reducing energy consumption, steel plants can increase profitability.
By allowing precise control of motor speed, variable frequency drives (VFDs) not only reduce energy costs by 30% or more, they improve process control, reduce waste/spoilage, and help improve product quality.
But VFDs Can Damage Motor Bearings and Shut Down Processes…
But, VFDs can damage motors. They induce voltages on the shafts of the motor they control — voltages that can discharge through motor bearings, causing fluting and catastrophic motor failure.
