MOVITRANS® line – contactless long-distance energy transfer system

If you need to bridge long distances quickly and flexibly without long conveyor belts, mobile materials handling technology is a must. If you also want to avoid cumbersome, high-maintenance cable carrier / conductor rail systems or fixed floor installations and instead benefit from freedom and flexibility in your energy transfer project management, our MOVITRANS® line solution is ideal.

MOVITRANS® line ensures perfect energy transfer, even over long distances. It is a contactless, quiet, wear-free and low-maintenance system. No room for a control cabinet? With MOVITRANS® line, you also save time and space.

How do we achieve this? It's simple! With MOVITRANS® line, the power socket rides along, as it were. Energy is transferred contactlessly through an air gap, which enables a completely wear-free, low-maintenance electromagnetic connection. This contactless energy supply also makes it possible to achieve high speeds of over 10 m/s.

MOVITRANS® technology from SEW‑EURODRIVE works on the principle of inductive power supply. Electrical energy is transferred continuously along the route via a line cable that benefits from incredibly simple, flexible installation and is easy to reposition if you subsequently want to modify or add to it. This makes complex, cumbersome and high-maintenance systems consisting of cable carriers, conductor rails and fixed floor installations a thing of the past.

Features

Comprehensive and unit-independent solution

  • The technology is based on the principle of inductive energy transfer.
  • Electrical energy is transferred continuously along the route via a line cable that benefits from flexible installation.
  • When using the new system with a wedge-shaped cable design, there is no need for time-consuming concrete sawing work or grouting of the grooves.
  • The electromagnetic connection takes place through an air gap – a low-maintenance and wear-free process.
  • Contactless energy transfer is emission-free and resistant to contamination from external sources.
  • The simple operating principle offers significant practical benefits in system operation.
  • Complex, cumbersome cable carrier and conductor rail systems and fixed floor installations are a thing of the past.

Safe disconnection

SAFS:
Safe disconnection of the power supply

To prevent people from being affected by invisible electromagnetic fields, our MOVITRANS® technology benefits from the unique "SAFS" safety function. This abbreviation stands for Safe AC Field Stop (AC = alternating current). This can be used advantageously, for example, when the line cable is not in use or for vehicle maintenance purposes.

SAFS ensures the magnetic field is safely deactivated if there is no mobile vehicle for loading on the route or if it is not currently in use. The SAFS function complies with ISO 13849 performance level d (PL d) and the IEC 61800-5-2 standard for drive systems.
