摘要：谐振耦合式无线能量传输是一种新的非接触式能量传输技术，能实现无线能量驱动电机。该文从电路耦合模型出发，分析系统传输功率与系统参数之间关系，从而对线圈进行了优化设计，使其达到最佳传输效果。最后设计了一台实验样机，该样机利用两个相同频率的谐振铜线圈产生强耦合，使电能以无线传输的形式实现了在一定距离范围内驱动直流小电机。实验结果验证了该设计方法有效性。

Abstract:  Magnetic resonance coupling is a new technology for wireless power transmission, which can drive motor via wireless energy. In this paper, the wireless system based on coupling model of circuit was analyzed, and the relationship among transmitting power and coil sizes was researched, further more, the best transmission effect was obtained to optimize the design of system. At last, a wireless power transmission prototype was designed, the prototype using two same frequency resonant copper wire produce strong coupling, it was able to drive small DC motor within a certain distance via wireless. The experimental results verify the effectiveness of the proposed method.
