Frequency Selectable Induction Heating Targets

This paper examines a scheme for developing frequency selectable induction heating targets for stimulating temperature sensitive polymer actuators. “Frequency selectable” implies that each target has a frequency at which it heats preferentially compared to other remaining targets. Single-turn conductors whose critical dimensions are small compared to their associated skin depth (over the freque...

Development of a Model for Induction Heating

Modelling and Simulation of Induction Heating

This paper deals with the simulation of induction heating of conducting workpieces with a complex shape and topology. We assume that its conductivity is high, which, owing to the skin effect bars the fields from penetrating deep into the conductors. This justifies the use of a simple magnetostatic model that describes the magnetic field outside the workpiece and the inductor. Field concentratin...

Computer Simulation of Induction Heating Processes

Induction heating computer simulation is a powerful tool for process design and optimization, induction coil design, equipment selection, as well as education and business presentations. The authors share their vast experience in the practical use of computer simulation for different induction heating and heat treating processes. A comparison of simulation versus the experimental “trial and err...

Computational Modeling of Induction Heating Process

An accurate 2D steady state mathematical model for induction heating process is described and additional results of electromagnetic field, eddy currents distribution and volumetric heat generation have been computed for a sample setup using a finite element method. For the calculations, the input voltage of induction coil is set to be 200 V with a frequency of 10 kHz. It was shown that for the ...
