Engineering calculators
Seven engineering calculators for induction heating system design — power sizing, frequency selection, skin depth analysis, current density visualization, coil design, shrink fitting, and wire/strip line speed. Based on fundamental electromagnetic and thermal physics.
Calculator Tools
Power Calculator
How much power do I need? Enter material, geometry, target temperature and heat time to calculate the required power supply kW rating.
Frequency Calculator
What frequency do I need? Enter material, part geometry and process type to get the recommended frequency range and skin depth.
Skin Depth Explorer
Interactive log-log chart comparing skin depth vs frequency for 10 common materials. Toggle materials, hover for values, click to highlight.
Current Density Profile
Visualize how eddy currents distribute across a workpiece cross-section. Adjust frequency to see the transition from through-heating to surface-heating.
Coil Design Estimator
Estimate solenoid coil parameters from workpiece dimensions — inductance, coupling factor, impedance, current, and water cooling requirements.
Shrink Fit Calculator
Calculate the required heating temperature for interference fit assembly — enter shaft and bore dimensions, material, and desired clearance.
Wire & Strip Line Speed
Calculate maximum line speed for continuous induction heating — wire annealing, strip processing, tube heating. Enter material, geometry, power and target temperature.
