The thermal magnetic material (TMM) is one of new materials, which the permeability is varied with the temperature change, and it is possible to use the TMM for the thermostatic switches. In order to analyze the dynamic characteristics of the thermostatic switches, we have to consider not only the magnetic field, but also the heat transfer and the motion of the armature, simultaneously. In this paper, a new method coupled with the magnetic field analysis, the heat transfer analysis and the motion equation is proposed by using the 3-D finite element method with edge elements. The validity of this method is verified through the comparison of the measured results. The usefulness of this method is confirmed by applying to the dynamic characteristics analysis of the thermostatic switch.
