Variable Speed Drives adjust a motor’s speed to closely match output requirements, rather than just running at full speed all the time.

BG Energy Solutions delivers to its customers eVSD, a simple, retrofit device that can be fitted to AC Induction motors to reduce their electricity consumption.

The result? Your building’s appliances function effectively – but use less electricity.

How do they work?

Most motors are over-specified. There is no need for them to function at the highest demand level all the time.

  • The eVSD device ensures the motors run at an appropriate speed and torque.
  • Using eVSD to slow a fan or pump motor from 100% to 80% can save as much as 50% of the energy used.
  • eVSD is suitable for every fan, pump and HVAC motor above 1.1kW.
