MOVITRANS
®
consists of stationary and mobile
components for contactless energy transfer to
mobile electrical consumers. The required en-
ergy is transferred via electromagnetic fields
(contactless) from a coil or an insulated station-
ary conductor via an air gap to the mobile con-
sumers (vehicles) selectively or along a track.
Compared to the conventional energy transfer,
e.g. using contact lines or charging stations, the
MOVITRANS
®
system is particularly wear-free
and thus maintenance-free. With the contact-
less energy transfer system, there is no longer
need for heady batteries which sustainably af-
fects the design of the mobile assistance sys-
tem. The line cables on the main tracks supply
the vehicles with energy when they cross them.
Charging a battery is no longer required. The
vehicles can thus be used in 3-shift operation
as no breaks for charging the battery are re-
quired. At the same time, fewer mobile assis-
tants are needed compared to a system with
battery-supplied vehicles. Resources are used
responsibly, especially regarding the inevitable
battery exchange for battery-supplied vehicles.
A further example is
our short-term energy
storage system
for flexible tracks. To store
electric energy, the DC voltage storage unit is
expanded with electric capacitors or batteries,
realized with energy storage modules with in-
novative double-layer capacitors. Using a DC
voltage converter connected between the supply
system connection and the storage modules, it
is possible to individually control the stored en-
ergy. The storage unit is charged actively and
the stored energy can be used by the consum-
ers. Using the short-term energy storage system
from SEW-EURODRIVE, application-specific pow-
er supply interruptions can be bridged and ex-
tremely flexible plant concepts can be realized.
In regard to the digital factory and the impor-
tance of swarm technology, this system plays a
central role in creating the future. The reduced
installation technology of such systems comes in
handy especially in case of power failure or line
interruptions.
