AB  - A complete time domain thermal model of a compression driver was developed using COMSOL Multiphysics in order to predict heating phenomena and minimize potential damage. Heat transfer in the model relies on conduction, natural convection, and radiation all together ensuring a rigorous approach. Considerations accounting for power compression are also included in order to provide detail in the temperature prediction through time. Results are satisfactory and represent the outcome of an accurate method to predict operation limits of such devices, together with the change of magnetic induction in the air gap due to thermal effects.
