Airports
Drum motors take up less space
than external drive systems
allowing more space in current
BHS footprints to expand.
VDG drum
motors are
permanently
lubricated,
so vibration
analysis isn't
needed.
It also identifies equipment irregularities with enough
time to ensure that materials required to repair or replace
the equipment is available on-hand.
" Both these, and other benefits drive towards a status-based
maintenance approach instead of a time-based
maintenance plan, allow repair and replacement when
components require it, and not necessarily based on a calendar-driven
schedule, " Studdiford says.
" This could also lead to an increased life cycle of equipment
while monitoring components during their decline
instead of replacing based on the manufacturer's recommendation.
There are huge overall cost savings to be had with
regard to the life of a BHS and its overall total cost of ownership, "
he adds.
Nord Drivesystems recently introduced its generation of
IE5+ motors utilizing a reduced noise, high efficiency design
suited to acoustically sensitive areas in airports. They present
flexible mounting solutions whether direct mounted to a
gearbox or mounted to a NEMA or IEC adapter.
The two frame sizes, 70 and 90, offer a power range from
0.5 - 3HP and a speed range from 0 - 2,100 rpm. IE5+ synchronous
motors are outfitted with an integrated encoder
that can be programmed for precise control over speed, synchronization
and position.
Permanent magnet motors (PMM) like the IE5+ offer durability
and sustainable energy savings for airports.
" We've seen projects in testing where it provided double-digit
efficiency gains over previous installations, " Chandler
says. " However, we also look at how what we can take
out. We've looked at direct drive solutions, eliminating
pulleys and chains so there's a lot of opportunity in
increased gains. "
Studdiford says the permanent magnet motors promise
higher performance and generally lower weight than traditional
AC induction motors. They also tend to have a smaller
footprint, which makes permanent magnet motors good for
retrofitting older systems.
" While more expensive than induction motors in their initial
product cost, PMMs and their energy savings can realize
a full return on investment in as little as two years, " he says.
" They are also synchronous, which allows them to work in
applications where induction motors cannot. "
Drum Motors Drive Potential
North American airports and airlines want their luggage systems
to handle twice as many bags on a similar footprint as
their current baggage handling system. Drum motors provide
a solution to meet this demand.
Drum motors hermetically seal the electric motor and
gear reducer inside the head drive roller. This eliminates the
need for external drive system components, such as chains,
sprockets and chain guards. It also eliminates the need for
pillow block bearings because the shafts on a drum motor
are stationary.
" When you use our drive system, you can put conveyors
closer together in a closer space so you can achieve better
space utilization, " says Alex Kanaris, president and owner
of Van Der Graaf (VDF). " And using these drive systems
are going to cost them about 30 percent less than what
they're using now. "
