Abstract：To solve the problem of low transmission efficiency in wireless energy transmission of multi-degree-of-freedom motor,a wireless power transmission method based on magnetic coupling resonance was proposed.In accordance with the resonance principle,the wireless power transmission model based on magnetic coupling resonance was constructed,the impedance matching state was described by the reflection coefficient to obtain the optimal load impedance;the chaotic optimization algorithm was used to realize the optimization of coil loss rate and wireless power transmission for multi-degree-of-freedom motor.The experimental results show that the power output of the multi-degree-of-freedom motor reaches 893 W after using this method and the transmission efficiency is improved by more than 0.10.The power output and the transmission efficiency are enhanced simultaneously,indicating the feasibility and effectiveness of the as-proposed method.
