Modeling, design and analysis of an induction heating coil for brazing process using FEM

In this research a modeling, design and analysis of the most suitable dimensions and the number of turns of the induction coil required for a certain brazing process was done by using FEM. Ansoft Maxwell computer package is used for this purpose. The simulation determines the electromagnetic field distribution inside the work coil by the required excitation current and frequency. Then the optimal work coil is determined. Also, it is used to determine the required magnitude of the load resonant circuit capacitance to achieve this frequency. The simulation describes the expected behavior of the load parameters during the brazing process.
