Induction Heating Fundamentals and Advantages
📌 Induction heating uses high-frequency current in a coil to induce eddy currents in a workpiece, generating localized heat efficiently.
⚡ Key advantages include efficiency, precise control over heating time and power, localized heating only on conductive/magnetic parts, and being fast, clean, and safe.
🔬 Applications span industrial uses (hardening, melting, NDT) to domestic (cooking) and medical fields.
Factors for Improving Induction Heating Performance
⚙️ To improve efficiency and control, designers must investigate inductor design (shape, number of turns, position) and consider field shapers to localize heating further.
🌡️ Key simulation factors include adjusting the frequency, testing different materials (including temperature-dependent properties like conductivity), and managing input power while cooling the coil.
💨 The impact of workpiece speed (translation or rotation) on heating needs investigation, especially regarding generated eddy currents.
Simulation Workflow and Capabilities using E²M Works Solution
💻 The E²M Works solution is co-developed inside Autodesk Inventor and SolidWorks, allowing for simulation without exporting geometry, transforming CAD into a virtual prototype platform.
🔍 Available simulation solvers include Magnetostatic, Electrostatic, AC Magnetic (Frequency Domain), and Transient (Time Domain), supporting analyses from DC up to a few MHz.
🔥 The platform supports coupled simulation, automatically using electromagnetic losses (ohmic, eddy current, core loss) as the load for transient thermal analysis to compute heat over time.
Case Study: Induction Hardening of a Gear
⚙️ The case study focused on hardening a steel gear (Module 2, 9 teeth) using frequencies between 20 and 40 kHz, where skin depth ranges from to .
💡 Comparing three coil designs (open cylindrical, cylindrical, multi-turn) showed trade-offs, with one configuration yielding a more uniform and symmetric heat distribution.
📈 Increasing the frequency significantly increases generated power and induced losses, but also raises the peak temperature—for instance, moving from () to () in the gear tooth.
Key Points & Insights
➡️ Designers can optimize designs by varying parameters like coil geometry, frequency, and current within a single integrated platform (CAD/CAE).
➡️ Using temperature-dependent material properties (e.g., conductivity vs. temperature) in the simulation provides a more realistic prediction of the final temperature profile compared to constant material properties.
➡️ The software allows for parametric simulation, enabling the automated testing of results versus various combinations of geometrical and electrical parameters (e.g., current, frequency, dimensions).
➡️ The presented simulation results showed very good agreement when validated against both third-party tools and available experimental data.
