Abstract

A contactless decentralized power supply is proposed with communication capability through only one transformer. A prototype of a wireless transmission system of power and information (WTPI system) was built, and the two-axis position controls of servo motors were achieved by transferring the power and signal through one rotatable high-frequency transformer. The proposed concept can be applied for robotics and numerical control (NC) machines
