Abstract

This paper presents a novel construction of VCM with moving coil by wireless power supply based on the electromagnetic induction principle. By the proposed VCM, the problem of aging and broken of power supply line caused by the repeated movement can be overcame, and the requirement of repeated movement of moving coil with high frequency for a long time can be satisfied. This paper is organized as follows. Firstly, the construction of the proposed VCM is introduced. Secondly, its power-driven circuit based on interleaving double switch forward converter is provided. Finally, a control strategy of reciprocating motion is proposed. The effectiveness of method is verified by simulated results.
