| Abstract: | Aiming at the defect that voice coil motor is prone to failure in long-term reciprocating motion, a new voice coil motor structure is proposed, which cancels power supply lead and uses electromagnetic induction principle to transmit non-contact electric energy. In this paper, the mathematical model of the power supply structure of the new voice coil motor was deduced and analyzed, and the air gap flux density under different permanent magnet distribution and structure size parameters was analyzed by the finite element optimization analysis software, and the corresponding optimization ideas were put forward. Finally, the size optimization design of the permanent magnet magnetic circuit structure and the power supply electromagnetic circuit structure was completed, so that the new structure can meet the design requirements, and a prototype was made to verify the optimization results |
