Aiming at problem that in practical application

wired charging sensor is easy to cause a series of safety problems in industrial and mining enterprises. Basesd on the theory

establish a mutual inductance equivalent model of wireless power transmission system. In order to analyze the impact on the system of mutual inductance and power efficiency

energy transmission experiment system is designed. Feature analysis of transmission distance and deflection angle

by changing the test load coil position on the opposite side coaxial

ipsilateral coaxial

different shafts characteristics of three typical locations. The results show that through the appropriate collocation of distance and angle can achieve better transmission efficiency. It can play a guiding role on practical application of the magnetic coupled resonant wireless power transmission system.
