Movitrans, a contactless energy transfer system from SEW-Eurodrive, causes no electromagnetic interference and is insensitive to outside influences. The device has been EMC tested according to BGV B11 and is a suitable power supply system for mobile applications. The system works on the principle of inductive energy transfer. Electrical energy is transferred from a conductor in a fixed installation to one or more mobile loads without contact. Electromagnetic coupling is realized via an air gap and is not subject to wear.
