Variable Speed Drives

What is an AC Drive?

Making our world and way of living more sustainable

An AC drive is a device used to control the speed of an electrical motor in order to: 

  • enhance process control
  • reduce energy usage and generate energy efficiently
  • decrease mechanical stress on motor control applications
  • optimise the operation of various applications relying on electric motors

Drives can also be utilised to convert energy from natural and renewable resources like the sun, wind or tides, and transmit it to the electrical network or use it for local consumption. In hybrid technologies, AC drives are used to combine conventional energy sources and energy storages to create total energy management solutions.

AC drives are also known by various other names such as adjustable speed drives, adjustable frequency drives, variable frequency drives, variable speed drives, frequency converters, inverters and power converters.

Did you know?

  • Emerging economies are driving the increase in energy consumption
  • 20% of the world’s energy consumption is electrical energy
  • More than 50% of electrical energy is used by electrical motors
  • 75% of AC drives are used on pumps, fans  and compressors
  • Global electrical energy consumption could be reduced by 10% if AC drives were used in every suitable application

The need for energy conservation in order to save the environment is a key driver in the development of speed control devices, and AC drives provide the optimum method of controlling the speed of electrical motors to match load demand. Even small changes in motor speed can cause significant changes in energy consumption.

AC drives are well hidden, but nevertheless they play a major and very necessary role in modern, everyday life by making the world and our way of living more sustainable.

NHS Car Park

NHS Warwick Hospital making significant operational cost savings

Digicon installed and commissioned variable speed drives to AHU fans and heating pumps at Warwick Hospital. The drives were integrated into the existing Johnson Controls building management system to provide significant energy and operational cost savings.

Siobhan Hill, Energy Manager for South Warwickshire NHS Foundation Trust, said, “This scheme is one of several measures we are implementing at our facilities to reduce energy consumption, reduce bills and help to combat climate change. As a specialist in this field and due to their sole focus and support geared toward variable speed drives, Digicon were the obvious choice. The speedy response to our enquiry and professionalism with which the whole process was under- taken from start to finish was excellent.” Siobhan added, “The initial report was extremely concise and very helpful in securing funding for this project. We were equally pleased with the time scaling of the installation to ensure no disruption to the hospital. One major fact that also had to be considered was response times and support in the event of any problems. Digicon proved to be excellent following a minor problem, as we had a Digicon engineer on site within 3 hours following my initial phone call. They also have 24/7 technical support available if needed. I would have absolutely no problem recommending Digicon to anyone in the future.”

National Leisure Group makes huge savings with Digicon Drives

As part of the UK's ongoing mission to monitor and reduce CO2 emissions and energy usage, a National Leisure Group consisting of more than 90 health clubs across the UK found that their pumps and fans were constantly using more energy than was required.

After carrying out extensive site surveys and running free of charge trials, controls experts Digicon Solutions evaluated that the pump and fan installations at the Clubs had all been sized to provide copious amounts of reserve capacity that would not be needed during day to day operation. Our expert engineers at Digicon, discovered that the majority of the applications were fitted with single speed starters, which meant the pumps and fans always operated at full speed, irrespective of the actual requirements. This wasted money and created far more energy consumption than acceptable in these challenging times, where energy saving and reduced CO2 emissions are paramount to ensuring a greener planet.

Digicon suggested that fitting variable speed drives with timers, CO2 sensors, day/night real time clocks, and humidity sensors would allow the motors' operating speeds to be matched to the demand. This significantly reduced the energy usage.

Our experts advised that the potential for savings in applications of this type is excellent, as the power used is proportional to the cube of the speed.

To date, Digicon have installed more than 520 Variable Speed Drives for over 90 Centres within this Group across the UK. By using our Drives, the group is currently making savings of over £400,000 per year. 

We have also installed approximately 600 additional drives to other leading Leisure Clubs nationwide!

By using a Variable Speed Drive (VSD) to reduce the speed of a pump or fan application you can typically achieve the following savings;

  • reduce motor speed by 10%, achieve a 27% reduction in energy consumption
  • reduce motor speed by 20%, achieve a 48% reduction in energy consumption
