Abstract :
This paper presents a transient analysis method coupled with the equations of magnetic field, heat transfer and motion using the three-dimensional (3-D) finite-element (FE) method. This method is applied to predict the dynamic response of a thermostatic switch for temperature sensing and high current interception. In this method, the thermal nonlinearity of the permeability of temperature-sensitive magnetic material (TSMM) is considered. The effectiveness of this method is verified through the comparison of the measured results.
