In this paper, an equivalent circuit model for magnetoelastic resonator is introduced. Elements of the model consist of coil inductance, magnetization of the resonator, a parallel RLC resonator representing the resonator resonance and a transformer indicating conversion ratio. This model suggests an approach to describe electrical response and characteristics of the resonator subject to geometries and excitation conditions. Moreover, corresponding techniques for extraction of parameters of the system are developed. Experimental results show that the model gives reasonable approximation of the system and accurately predicts behavior of the system.
