The proposed magnetic coupler can overcome the shortcomings of the contact slip rings equipped in traditional rotating equipment and reduce the impact of rotating equipment metal shafts on the system, and is characterized by non-contact, high efficiency, wear free, safety and reliability. In this paper, the proposed magnetic coupler is optimized using finite element simulation software, and the circuit model of wireless energy transmission using S-S compensation scheme is given. Finally, the experiments demonstrated that the proposed magnetic coupler achieves 95% high efficiency output under the conditions of rotation and 5kW output power.
