Contactless power transmission – maintenance-free and up to 240W
High power density and maximum efciency with small dimensions
Burnt, bent or dirty contacts are often the cause of timeconsuming and costly
production failures. This is all the more true of applications requiring frequent
plugging cycles. To name but one example, these include industrial robots
performing frequent tool changes. Here, the level of wear is especially high.
FreeCon Contactless allows power to be transmitted via an air gap by means of an
inductive resonance coupling – it’s a solution that’s completely wear-free and
especially efcient. Double the power density and a far higher degree of efciency
is achieved compared with comparable solutions that are available on the market.
Thanks to FreeCon Contactless, you can avoid contactrelated failures and cut your
maintenance costs considerably. It even opens up completely new areas of
application, since for the rst time ever an automated process can be used to
establish a connection which previously would have to be plugged manually. The
process of charging driverless transport systems, for instance, can be automated.
Highmaintenance slip ring transmitters can be replaced too, since
FreeCon Contactless securely transmits power even in the case of rotational
movements.
Wear-free electrical connection that can be switched as part of a
controlled process
FreeCon Contactless enables reliable and contactless transmission of up to
240W of power with compact dimensions and maximum efciency. The
transmission can even be controlled via PLC. It is therefore possible to switch
10A directly via the PLC without the need for an additional contactor.
High power density with
maximum efciency
For the rst time ever, 240 W of power
can be transmitted contactlessly via two
especially small modules. Extremely low
transmission losses translate into an
efciency level of up to 93%
F ≤ 93 %
