Integration of inductive energy transfer into the guidance of a linear direct drive

Inhalt:
Inductive energy transmission is an alternative to cable-based energy supply in some drive technology applications. It also offers potential for use in the field of linear direct drives as a replacement for the drag chains currently used in industry. Its feasibility has already been demonstrated in previous work. The transmission system was adapted to the drive without changing the overall design of it. With the aim of reducing the number of components required, research was then carried out into the development of a drive concept for function integration. For this purpose, a linear direct drive with linear shaft guides made of hollow shafts was developed. The hollow shafts fulfill the function of guiding the drive unit on one hand and open up the option of supporting the primary coil of the transmission system on the other. In initial tests, the influence of these shafts on the transmission system was investigated. Here it was found that the choice of material influenced the efficiency. The decisive factor was the increase in the resistance of the primary coil. Finally, the feasibility and functionality of the entire drive was demonstrated by commissioning.
