Compressors with variable-frequency drives work more efficiently than conventional units, and reduce maintenance costs and noise levels. Compressed air is a vital utility to most commercial and ...

A variable frequency driven (VFD) is a type of motor that controls the levels of frequency and voltage that alter the speed of an electric motor. The drive alters torque and motor speed and can be ...

October 2025 marks the 50th anniversary of ABB’s Low Voltage Variable Speed Drive (LV VSD). Developed by Finnish engineering ...

For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

As a hybrid technology that combines mechanical and electrical systems, electrohydraulic variable speed drives allow for motor speed adjustments to conserve energy and provide precise control over ...

This month marks the 50th year since ABB’s Low Voltage Variable Speed Drive (VSD) was first brought to market.
