To solve the issues including the inflexibility, connector wear, and electric shock risk in contact charging system for inspection robots, the wireless charging system for inspection robots is introduced in this paper. The circuit model of this paper is developed based on the mutual inductance theory. The expressions of the receiving power and the efficiency are derived. The coordinate calculation method for mutual inductance between non-coaxial rectangular spiral coils according to the movement characteristics of inspection robot is presented. According to the calculation method, the characteristics of the receiving power and the efficiency varying with the position change of the receiving coil are investigated. The location of the positioning device for starting the wireless charging system can be selected based on the system characteristics. The theoretical analysis is verified by experiments.
