Advances in Variable Speed Drives Ease ComplicationsJul 21, 2017
Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% of the world’s electricity for industrial and consumer applications. The key benefit is to provide new and improved process control, while also boosting power factor and overall system efficiency (energy savings). VSDs are used in a multitude of applications, ranging from relatively simple applications (like pumps and fans) to more complicated applications (e.g., winders and dynamometers).
