Variable Speed Drives in Industrial Automation: How VSD Technology Improves Motor Efficiency and Process Control
- 〡 by WUPAMBO
Variable speed drives (VSDs), also known as variable frequency drives (VFDs) or AC drives, regulate energy flow between the electrical supply and motors. They convert incoming AC power to DC, smooth it through capacitors, and then invert it back to AC with adjustable frequency and voltage. This process ensures motors run at the exact speed or torque required by the application.
