MOVITRANS
®
is made up of stationary and mo-
bile components for contactless power supply to
moving electrical loads. The required energy is
transferred via electromagnetic fields (contact-
less) from a coil or an insulated stationary con-
ductor via an air gap to the mobile consumers
(vehicles) either selectively at specific points or
along a track. Compared to conventional energy
transfer, e.g. using contact lines or charging
stations, the MOVITRANS
®
system has particularly
low wear, making it maintenance-free. With the
contactless energy transfer system, there is no
longer need for heavy batteries, which has a long-
term effect on the design of the mobile assistance
system. 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 required.
At the same time, fewer mobile assistants are
needed compared to a system with battery-sup-
plied vehicles. Resources are used responsibly,
especially regarding the inevitable battery ex-
change for battery-supplied vehicles.
Another example is
our short-term energy
storage system
for flexible travel tracks.
To store electric energy, the DC voltage storage
unit is expanded with electric capacitors or
batteries. This is made possible by energy
modules that are made of innovative double
layer capacitors. The DC-to-DC converter
connected between the grid connection and the
energy modules allows individual control of the
stored energy. The storage unit is charged ac-
tively and the stored energy can be used by the
consumers. Using the short-term energy storage
system from SEW-EURODRIVE, application-
specific power supply interruptions can be
bridged and extremely flexible plant concepts
realized. In regard to the digital factory and the
importance of swarm technology, this system
plays a central role in creating the future. The
reduced installation technology of such systems
is particularly useful during power failures or line
interruptions.
