Aiming at the power supply problem of high-speed rotating equipment, a wireless power transfer system based on U-shaped core coupling mechanismwith a primary coil is proposed. Firstly, the transfer model of the U-type coupling mechanismwireless power transfer system is established.*e expressions of transfer power and transfer efficiency are obtained by theoretical calculation, and the factors affecting the transfer characteristics of the system are analyzed. At the same time, the magnetic field distribution of the system and the coupling parameters change when the relative position of the primary and secondary coils changes through simulation analysis. Finally, an experimental platform is established for experimental verification.*e results show that the system can obtain 1.72w output power with 51.19% transfer efficiency when the distance between the secondary coil and U-core is 15mm and 30mm, respectively. *e transmission efficiency and power of the primary coil and secondary coil under different misalignments are tested and compared. It is proved that the wireless power transfer system based on U-type couplingmechanism can effectively realize the stable power supply of the rotating equipment monitoring system.
