Abstract

A contactless energy supply for electrical consumers mounted on the mobile part of a linear motor is provided, the energy supply being provided without additional voltage sources. A higher frequency energy supply field is superposed over the propulsion field, the energy supply field being inductively decoupled using the energy transmitting interface of the secondary part, and supplying consumers mounted on the secondary part with energy.
