Introduction: 9 tips to increase energy eciency
with drive technology
Energy prices are soaring to unprecedented heights. It is time
to review energy saving measures to keep costs in check as
much as possible. With this 9-point checklist for energy-efficient
of energy guzzlers in your facilities and measures to leverage
energy efficiency in motor driven equipment by utilizing drive
technology. You will learn where you can start working on
increasing efficiency, and in doing so, save costs. After all, electric
drive technology is a key technology for increased energy
efficiency. It is currently the most effective, fast, and easy solution
for reducing energy consumption quickly and significantly.
Speed control of electric motors can operate almost all
applications like conveyors, elevators, refrigerator compressors,
air conditioning systems in buildings, pumps and many other
industrial applications in an energy-optimized manner. In its
World Energy Outlook 2016, the IEA estimates that global
electricity consumption can be reduced by 8 percent by 2040
if AC drives are used in all suitable applications - and if they are
used efficiently.
This energy efficiency checklist helps with useful tips and shows
where the greatest potential lies that can be lifted quickly. These
measures pay off twice: Every kilowatt hour of electricity saved
not only reduces your energy costs, but also minimizes your
companys CO

footprint.
Speed control matters: Leverage energy-
saving potential in all your motor
applications quickly
Pick the low hanging fruits: Check for
fans and pumps in your applications and
facilities

Good to know Advice
AC drives do not only help operators save energy and energy costs,
but also help saving costs for operation, maintenance, and repair as life
cycle costs are reduced. Often, AC drives with speed control really is the
best choice to save energy and costs.
To learn more about the energy-efficient use of AC drives, go directly to
checkpoint 3.
Consider softstarters
In applications where speed control is not an option, it is worth
considering using a softstarter which is equipped with a bypass.
Without a bypass, the device will create unnecessary losses in motor
operation.
In general, softstarters are typically used in applications running directly
on the mains. They are designed to protect your electric motor from
possible damage and at the same time extend its lifetime and the
lifetime of the whole system by decreasing the heat caused by frequent
start/stops, reducing the mechanical stress on the motor and its shaft,
amongst others.
Identify all your motors > 0.75 kW
which are not speed controlled yet
but have a potential. Do you use
valves, dampers, or other technologies
to control the fl
ow or speed in
applications? These are perfect
candidates to start with!

plant the us of AC drives on rotating
equipment creates net production of
both electricity and heat and reduces
its carbon footprint by 35%.
Read much more about it
Electric motors are responsible for around 40 percent of the world’s electrical energy consumption. In
industry, their share is as high as 65-75 percent depending on the region and sector.
As energy becomes increasingly expensive, variable speed control of electrical motors has proven to
be one of the most effective cost-reducing measures available. Forapprox. 60-70 percent of motors it
makes sense to apply speed control making it a good starting point for your energy efficiency journey.
Large electrical machines are of course of interest, but a much bigger potential might still hide in all the
small motors you use in your applications, processes, and facilities. Let’s leverage this potential.
