Dynamic Analysis Method of Linear Resonant Actuator With Multimovers Employing 3-D Finite Element Method

This paper proposes the dynamic analysis method of a linear resonance actuator with multimovers under PWM (Pulse Width Modulation) feedback control employing the 3-D finite element method (FEM). The effectiveness of this method is shown by the comparison with the experimental results. Furthermore, the effect of a link-spring on each mover motion is clarified.
