A New Inductor for Transverse Flux Induction Heating

Five‐phase travelling wave induction heater for continuous heating of flat material

“…Researchers proved that the in short pitch coil the obtained temperature range is wider and better than the full pitch coil. Also, the heat uniformity is more than the full pitch coil and the time rise time is shorter than of full pitch [10, 11]. Moreover, researchers find out that the arrangement of coil windings could affect the heat distribution.…”

Closed and quasi‐closed yoke configurations for travelling wave induction heaters

“…Many aspects which are affecting the performance of the heater have been considered, and the relationships between the air‐gap and pole‐pitch, the slot‐tooth ratio or slot‐depth have been analysed and improved in the literature such as crossed yoke, slot wedges, distributed vernier and slot less travelling wave induction heaters [7, 8]. However, definite criteria for the choice of the winding arrangement and the optimum design are not yet available [8]. In this paper, the possibility of focusing the magnetic flux lines to govern the eddy current density within the area faces of the heater is investigated.…”

“…Therefore, 2D or 3D FEAs is a universal choice for simulation and analysis multiphase systems. Both methods need a relatively long calculation time, which includes large quantities of work to input data and a previous knowledge of the poly‐phase exciting current (amplitude, frequency and phase) [8]. In this paper, numerical FEAs are used to investigate the electrical and thermal performances.…”
