Abstract
A vibrating motor is a multi-physics product in which there is coupling between electrical, magnetic, and mechanical domains. To obtain a more accurate analysis, nonlinear parameters, such as inductance, speedance, and force factor, are considered as functions of current and displacement based on the finite element method. By solving a voltage equation using a numerical iteration method, current and displacement at each frequency of the vibrating motor can be calculated. The validity of the analysis method was demonstrated by comparing the results of the experiment with those of the simulation and they were found to be similar.

Nam et al proposed a novel design of a linear actuator with a large magnetic force to reduce the response time, which was analyzed by a transient analysis in the mechanical domain [6]
In force this study, the nonlinear parameters are considered as respect to the inductance, speedance, factor, which are caused by the vibration of the motor, functions of displacement and current to analyze the performance of the vibrating motor using were considered as constant values
Summary
Electronic devices have fascinated people all over the world, with emphasis being placed on improving performance. A vibration actuator was developed based on active magnetic springs by taking advantage of polynomial fitting to outline the magnetic force characteristics [10], and Lee developed a horizontal linear vibrating actuator and modeled the mechanical domain by a two-degrees-of-freedom system that considered the electromagnetic and mechanical domains separately [11] In both cases, nonlinear parameters such as inductance, speedance, and force factors were not considered. In force this study, the nonlinear parameters are considered as respect to the inductance, speedance, factor, which are caused by the vibration of the motor, functions of displacement and current to analyze the performance of the vibrating motor using. To analyze performance of theand vibrating motor coupling using FEM and a considering nonlinear parameters of the vibrating motor is used for securing an accurate motor numerical iteration method.
