The energy supply mode of mine monorail crane is an important factor to determine the reliability and efficiency of the system. A mine monorail crane system based on dynamic wireless power supply technology was designed in this paper. The system is safe, environmentally friendly and convenient. The designed magnetic coupling mechanism has the advantages of high coupling coefficient and low loss. The simulation results prove the correctness and feasibility of the design.
