This paper designs and implements a contactless maglev rotating power transfer system with new rotary inductive coupled structure for the testing equipment on shaft of high-speed rotation applications. The magnetic FEM software is used to analyze the power transfer characteristics of the structure with magnetic poles. This paper extends the magnetic material of the structure to improve the coupling capability. Moreover, for the purpose to verify the stability of power transfer of the proposed rotary inductive coupled structure, this paper builds a brushless doubly fed motor and use its armatures of rotor as the power transfer target. In order to design an accurate structure, the three-dimensional printing technology is used to print its frame. Two permanent magnetic bearings are used to levitate the shaft. Finally, an integrated platform is constructed for the experiment. The maximum rotational speed of the shaft is 4800 rpm. The maximum output power received in load is 297W and the maximum efficiency is about 82%.
