Abstract

In installations including fixed and mobile structural elements and a rotary current motor as a drive, the rotary current motor can be used for the wireless transmission of both energy and/or data. The transmission from the fixed structural elements to the mobile structural elements of the rotary current motor is especially inductive. In the corresponding device including a rotary current motor including a stator and a secondary element, the secondary element is not embodied as a solid conductor with or without a laminated core, according to prior art, but rather as a laminated core including integrated windings which is the same as, or similar to, the stator.
