To meet the power supply demand of the contactless photoelectric data acquisition system for the aero engine rotor dynamic parameters,a contactless inductive power transfer device for high-speed rotating parts was designed. The basic principle of the contactless inductive power transfer technology is stated briefly. Considering the characteristics of high-speed rotation application occasions and the photoelectric data transmission circuit,a solution of using spiral line PCB plate and flexible soft magnetic sheet as the loose coupling transformer is proposed. The design method of primary and secondary circuits,and compensation parameter are given. The experimental results verify this scheme can realize the stable output of 7 V/3 A.
