The output energy theory model of the electromagnetic microgenerator was first studied. The most appropriate turns numbers and cross section radius of the induction coils were obtained by the theory analysis. Then finite element simulations were carried out to determine an optimum structure by the Software Ansoft Maxwell. The obvious change law of the magnetic induction intensity B in different direction was induced,and at the same time the induced electromotive force was generated with the relative position changing between permanent magnet vibrator and induction coil. Based on the model of all the simulation results,when the relative distance is about 1. 25 mm between permanent magnet vibrator and induction coil,the maximum output voltage and output power of the model are 2. 65 mV and 0. 6626 μW,respectively. The process of modeling and simulation analysis in this paper would provide for the overall structure design and fabrication of electromagnetic microgenerator.
