2D hybrid magneto-thermal model for PM induction heating device with rotating movement

A new 2D-hybrid model in cylindrical coordinates intended for the study of a transient magneto-thermal coupled problem is proposed. This used to evaluate spatiotemporal distribution temperature rotating aluminum billets heated by permanent magnets induction-heating device (PMIHD). The proposed hybrid consists coupling an exact analytical solution 2D magneto-harmonic field thermal analysis where dependence electrical and physical properties billet considered. Based on separation variables technique, serves induced current resulting power density loss nonmagnetic billet. Furthermore, analysis, based lumped network model, developed radial axial directions In order validate performances studied PMIHD are compared with those obtained Finite Element Method (FEM).
