Benefits of Using a Variable Speed Drive

Approximately one third of the world's electrical energy is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. This proves that significant energy efficiency improvement opportunities are available…

ABB Low Harmonic Drives

Harmonic distortion may disturb or damage sensitive equipment connected to the same circuit of a variable speed drive. Any distorted voltage and current waveform that deviates from the ideal waveform presents the potential to harm electronic…

Variable Frequency Drives for Wastewater

The flow and pressure of fans and pumps need to be controlled because water consumption varies during a day. The flow and pressure can be adjusted either electrically with variable speed drives or mechanically with fixed-speed solutions…
