The variable-speed
drive is an indispensable piece of equipment for a huge number of
applications, such as fans, pumps, mixers and conveyors. But why exactly are these
devices so invaluable? Find out as we reveal some of the advantages of
variable-speed drives.
Energy savings
This is undoubtedly the main benefit of a variable-speed
drive. Controlling an electric motor’s speed means the application consumes
only as much energy as it needs to, keeping costs and carbon emissions to a
minimum. ABB estimates that its drives across the world save about 115 million
megawatt hours of electricity each year, the equivalent of 14 nuclear reactors.
Reduced maintenance
costs
Starting, stopping and braking can easily be programmed to
reduce stress on mechanical equipment, lowering maintenance expense in the
process.
Quick return on
investment
The cost of installing a variable-speed drive can normally
be recouped via energy savings in less than a year. In some cases it’s as
little as a few months.
Easily retrofitted
into an installation
If you want to upgrade existing equipment which is
mechanically controlled by a damper or valve, there’s no need to replace the
whole system. Variable-speed drives are designed to be retrofitted into old
machinery, providing a significant energy-efficiency improvement.
Real-time clock
This handy feature allows the user to easily set up
programmes with different running speeds at selected times or on chosen days.
This offers flexibility and means equipment does not need to be manually
re-programmed every time a change is required.
Low harmonic
solutions
Harmonics (current and voltage distortion) are a regular
cause of power problems, but they may be reduced with variable-speed drives via
filters and chokes.
You cans see that a variable-speed
drive can solve many problems, so for more information give us a call on
