Trust the experts, variable speed drive installations with Digicon

Trust the Experts - VSD Installations

Digicon employ a team of Installation Engineers who are installing and commissioning drives all day, every day. Not only are our engineers specialists in the field, they also practice excellent H&S standards, as proven by our continued accreditation from Alcumus SafeContractor.

Our Installation Engineers train for years to qualify as electricians and even longer to gain the knowledge and skills required to install and commission Variable Speed Drives. VSD technology is always changing, and they receive specialist training on an on-going basis to keep up to date. Around 70% of the technical calls we receive are from clients who have purchased a VSD from us and are struggling to install or commission it. We don't mean to brag, but we know that we are good at what we do and our clients have peace of mind they are in the best hands with a Digicon Engineer. We practice robust H&S and compliance procedures and after each installation you will receive electrical test certificates and detailed commissioning/engineer reports completed by one of our qualified electricians. We have engineers based up and down the UK and more recently, a dedicated team in London and the South East. We can work around you, whether that is working in shut down periods, avoiding peak times or out of hours/weekend attendance.

I can hear you thinking that’s all well and good, but how much does it cost? We firmly believe that you get what you pay for these days, and we have seen budget prices resulting in unsafe electrical installations so we are always wary of companies who promise the world for very little expenditure. We are confident in the knowledge that our pricing reflects our quality of installation without breaking the bank.

Don't just take it from us... here are some of our clients recent comments:

  • "Send my regards to your whole team, fantastic work." - January 2018

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.

Energy Conservation Variable Speed Drives

Is Energy Efficiency Really Worth the Investment?

The upfront cost of investing in energy-efficiency solutions may deter some businesses from taking the plunge. There are many arguments that support this reluctance. Energy costs are indeed falling. Businesses in Germany are eligible for tax rebates on their energy supply. And, in the industrial sector, where electric motor systems account for 30% of global electricity consumption, it’s going to take a significant investment to upgrade motor efficiency class or install AC drives to optimise the efficiency of the motors.

On the other hand, there is plenty of evidence to demonstrate why energy efficiency is justifiably legislated, and that it does, in fact, have a considerable payback.

More information can certainly break down some of the barriers. Here’s a quick example. It’s a well-known fact that AC drives reduce the electricity consumption of motors under variable torque loading (for example, with fans and pumps). And the return on investment in AC drives can be as little as a matter of months. Copenhagen’s luxury business hotel, the elegant Crowne Plaza Copenhagen Towers insisted on state-of-the-art energy technology in its design. In order for energy consumption to be as low as possible, an innovative ground-water heating and cooling system equipped with AC drives was installed.

Energy savings through system optimisation

There is a very high potential for energy savings through system optimisation. Systems can be reconfigured, to work in a more efficient way, and drives are an important technology that is an enabler for these optimisations.

In addition, AC drives can also be configured to run in regenerative mode where braking energy is fed back into the power supply instead of being lost as heat. You can read more about reduced energy costs achievable when using the VACON® NXP range of common DC bus drive products here.

So, we find ourselves in a catch 22 situation. Introducing energy efficiency measures requires investment. Sometimes the benefits outweigh the costs, sometimes not. The basic rule of thumb is to examine all aspects – technical, commercial and logistical – and take into account the entire lifecycle of the system.

  • Every measure has side effects. Weigh up the side effects against the advantages
  • Consider lifetime costs. A low-purchase cost doesn’t necessarily equate to low operating costs
  • Wherever possible, consult experts, such as Digicon Solutions, to clarify the technical advantages and disadvantages of your investment

In times where energy efficiency is high on the political agenda and resources are getting scarce, it’s important to remember to save energy – but, for the sake of our businesses, not at any price. Let’s ensure that we make smart investments, ones that pay off for our industries and our societies and that create a better tomorrow for our future generations.

Four Reasons Why Motor Independence Matters

Whether we are genuinely interested in having a positive effect on the environment, or simply following the ever-intensifying standards and regulations, optimizing the energy efficiency of our motors and motor controllers is something we cannot escape.

The energy-efficiency discussion has forced the development of new motor technologies and the reinvention of existing, older technologies. In the past, the induction motor (IM) was the only type of electrical motor used in industrial applications. It is still today one of the most commonly used motors in most applications. Synchronous reluctance motor technology, first invented a century ago, was originally optimized for size and torque. Thanks to the advent of AC drives, the high-efficiency synchronous reluctance motor (SynRM) can now be optimized for energy efficiency. And then there are internal and surface-mounted permanent magnet motors. Each motor type has its advantages and drawbacks; the key is finding the one that best fits your application.

For optimal energy efficiency, we then need to take a look at the motor controller – the AC drive. We all know that AC drives reduce the electricity consumption of motors under variable torque loading (for example, with fans and pumps). In addition, AC drives can also be configured to run in regenerative mode where braking energy is fed back into the power supply instead of being lost as heat. But how do we put the energy-efficiency puzzle together? Are there any constraints on what AC drives we can use with what motors?

Is bundling the answer?

Some motor suppliers offer a bundled motor and drive solution. On paper, this may seem the most convenient, and cost-effective, option. You’re only dealing with one supplier, compatibility is ensured and spare parts stock is minimized. However, it is important to keep an eye on the total cost of operation and the total lifecycle costs.

Think about support, for example. You still need to contact one person for drive support, another for the motor, and yet another for other equipment in the chain. That’s time consuming and potentially costly.

And what about replacements or retrofits? If the motor-drive bundle has been delivered to an installation in a remote region, and the exact same motor technology or compatible drive technology is not available, you’re looking at expensive, and potentially critical, downtime in a breakdown situation.

So, to come back to the headline, let’s look at the topic of motor independence and discuss why choosing an AC drive that adapts to any motor technology makes the most sense.

Reason 1: Flexibility

In this sense, flexibility means the ability to accommodate changing customer specifications and new technological trends over the entire lifetime of an application. If the drive is compatible with all state-of-the-art motor technologies, it’s just a case of including new motor algorithms into software updates of the drive when needed.

Reason 2: Fast replacement/retrofitting

As discussed earlier, there may be occasions when there are bottlenecks in delivery by a particular motor supplier. Similarly, it may be difficult to find an identical replacement motor, for example, in a remote site or location. In these instances, your only option might be to choose a different motor technology. Having a drive that’s compatible with all motor technologies gives you the freedom to choose another, more available, motor technology to avoid costly downtime.

Reason 3: One drive fits all

Now, we’re talking about multiple installations in, for example, large plants. Having the same motor-independent drives installed throughout the entire plant mean there’s a lower spare parts stock inventory, simplified staff training and more straightforward maintenance.

Reason 4: A future-proof solution

Using automatic motor adaptation, motor-independent drives can deliver optimal performance of any motor both now and throughout the lifetime of the application. Motor-independent drive suppliers continually test new motor technologies in order to develop new algorithms for compatibility. Independently optimized components adapt completely to a variety of applications. OEMs, for example, can therefore design the highest-performance drive/motor system for a specific niche application.

As you can see, choosing the right motor and drive combination doesn’t have to be a complicated, stressful task. If you’ve found the ideal motor for your application from a motor supplier you trust, there’s no reason to make any changes to that scenario. Where you can make changes, and changes that will improve your options, reduce potential downtime, simplify maintenance and lower lifecycle costs, is by choosing a motor-independent AC drive.

Vacon NXP and VLT® Lift Drive LD 302

Reliable operation and excellent ride comfort

Along with the proven Vacon NXP Lift Drive, Danfoss has now introduced its VLT® Lift Drive. Both drives are been designed from the outset to be easy to install and set up in elevator applications, and to be compatible with almost any type of elevator control system. And it’s available off the shelf from Digicon, which makes it possible to keep lift downtime to an absolute minimum.  Digicon work closely with its dedicated lift partner Digital Advance Control.

An ideal choice for retrofit?

The Danfoss NXP and VLT drives boast open architecture with the simple menu structure written in plain, easy-to-understand language.

Fitting the Danfoss VLT® Lift Drive proved to be as straightforward as expected and, after it had been installed, it was found to provide a much smoother ride than the old drive it replaced. It was also much quieter in operation ­ always a bonus in residential locations ­ as it has a specially controlled cooling fan that runs only when needed.

Energy and Money Conservation

A Brief Overview of VSD Technology

Electric AC induction motors run at a fixed speed and are ideally suited to applications where a constant motor output speed is required. However over half of all motor application have some kind of varying demand, such as fans, pups, winding reels and precision tools. Historically, processes would have been controlled using opening and closing dampeners and valves, or changing output speeds with gears or pulleys, all whilst the motor speed remained constant.

In the 1980’s, variable speed drives (VSDs) started appearing on the market offering an alternative method of controls. A VSD also referred to as a ‘drive’ or ‘inverter’ is an electronic power controller that is able to adjust the electrical supply to an AC induction motor with a corresponding change in the motor’s speed and torque output.

By implementing this type of control, a very close match between motor speed and the process requirements of the machine it is driving may be achieved.

Controlling the speed of a motor provides users with improved process control, reduced wear on machines, increased power factor and large energy savings.

Like a good wine, VSD technology has matured, and is now extremely versatile and offers a high degree of motor control. Motor speeds can be accurately varied from zero rpm through over 100% of the rated speed whilst the torque is also adjusted to suit.

Different options are available to suit a variety of applications and budgets. Basic VSD designs are used in simple applications such as fan and pump control whereas more complex versions are available for very precise speed and torque control, for example in multiple winders or materials forming applications.

VSD’s range from 0.18kW through to several MW in size; and are connected to the motor’s electrical supply.

In many applications, variable speed control can lead to substantial reductions in energy use. The use of VSD technology is particularly effective in fan and pump applications where an exponential relationship exists between the machine speed and the energy used.

Surely a 10% reduction in speed should equate to a 10% reduction in energy usage? This is correct when we are talking about a conveyor or a mixer, but fans and pumps are different.

The relationship between the speed and power of a fan or pump is called Cube Law. If you reduce motor speed by 10%, achieve a 27% reduction in energy consumption. Reduce motor speed by 20%, achieve a 48% reduction in energy consumption.

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
