T
oday’s production facilities are often textbook examples of
optimisation. Speed control of motors according to changing
needs improves process control, which is essential to ensure
high quality of the product produced. Accurate control from a VLT®
drive has positive effects on efficiency, material usage, environmen-
tal emissions, and production yield. A recent major trend is towards
increasing user friendliness and drives dedicated to and optimised
for specific applications.
Digitalisation drives down operating costs
The era of digitalisation has long begun and our dependence on
data, analytics, and the cloud will develop dramatically in the com-
ing decades. For ac drives, the potential is enormous and includes:
• Predicting customer problems and solving them before they start
• Enabling OEMs to run their applications even better
• Leveraging data utilisation to reduce costs for the customer
• New services drawing upon analysis of big data
With digitalisation developments, ac-drive programmability is en-
hanced with improved connectivity, data gathering and analysis
abilities, moving towards more customisable solutions. Digitalisation
also brings data handling, intelligence, and learning as totally new
fields of ac-drive software functionalities; end-to-end communications,
device availability, interoperability, and security on a wide variety of
digital platforms including your mobile phone.
Energy efficiency drives development in new motor tech-
nologies
For each application, a different motor technology can provide the
optimal performance characteristics. When the ac drive is compatible
Process optimisation
for
accuracy, quality, and reliability
with all typical motor technologies, then the system designer is free
to choose the optimal motor for overall system efficiency. This adapt-
ability will become increasingly important with widening diversity of
new motor technologies.
Energy storage and hybridisation
The increasing development of hybridisation involves equipping
general processes and machines which with energy storage to up-
grade performance and efficiency. VACON ® drives contribute to the
advantages of energy storage which include:
• Peak shaving, removing the need to dimension systems to peak
power demand
• Optimising performance by operating at the optimum point,
avoiding over- and underload operation
• Back-up power, which removes the need for idle reserve running
Outlook
With their diminishing size, increasing capabilities, and growing intel-
ligence, variable speed drives have become indispensable for both
the industrial and domestic sectors. In the present economic climate,
reducing total lifecycle costs and optimising system performance,
without compromising on product quality, are now more crucial key
factors in the early stages of the design process than ever before.
Danfoss Drives is a world leader in variable
speed control of electric motors. We offer
you unparalleled competitive edge through
quality, application-optimised products and
a comprehensive range of product lifecycle
services. Our low voltage and medium volt-
age VLT® and VACON® drives are used
with all major motor brands and technologies
in power sizes from small to large.
