Multi rotors permanent Magnet Heater for controlling temperature distribution in aluminum billets

摘要

Permanent Magnet Heaters, PMH, have been recently proposed as a possible high efficiency solution for the heating of high conductive metals. The optimal design of a Permanent Magnet Heater is presented with reference to a real industrial case. The design has been carried out by means of transient magnetic and thermal 2D and 3D Finite Element Models coupled with multiobjective optimization algorithms.
