Variable-Speed Drives (VSDs)

Detailed overview of innovation with sample startups and prominent university research


What it is

Variable-speed drives (VSDs), also known as adjustable-speed drives or frequency converters, are electronic devices that control the speed of electric motors. By adjusting the frequency and voltage of the power supplied to the motor, VSDs allow for precise control of motor speed, optimizing energy consumption and improving process efficiency.

Impact on climate action

Variable-Speed Drives (VSDs) under Energy-Efficient Industrial Equipment significantly advance climate action by optimizing energy consumption in industrial processes. By adjusting motor speed to match demand, these innovations reduce energy wastage, lower carbon emissions, and promote efficiency, contributing to a more sustainable and low-carbon industrial sector.

Underlying
Technology

  • Power Electronics: VSDs use power electronics components, such as transistors and diodes, to convert AC power to DC power and then back to AC power at a variable frequency.
  • Pulse Width Modulation (PWM): PWM is a technique used to control the average voltage and frequency of the output power by switching the power on and off at a high frequency.
  • Motor Control Algorithms: VSDs incorporate motor control algorithms that adjust the frequency and voltage of the output power based on the desired motor speed and load requirements.
  • Feedback Mechanisms: VSDs often use feedback mechanisms, such as encoders or sensors, to monitor motor speed and adjust the output power accordingly.
