Wireless power transmission for multi-degree-of-freedom motor applications based on magnetic field coupling

Abstract

This paper proposes a wireless power transmission scheme for three-degree-of-freedom motors’ applications in the field of bionics. In order to overcome the inconvenience of the rotating device with its charged wires, the wireless power transmission of the internal image visual acquisition device is realized. A three-coil receive structure suitable for motion device is designed. Using multi-physical simulation method, the parameters, magnetic flux and received power of single-coil receive structure and three-coil receive structure for wireless power transmission are calculated. The advantages of the three-coil receive structure are obtained. Finally, the accuracy and validity of the simulation are verified by experiments.
