MagComp Induction Heating Technology
MagComp has a technology for induction heating that improve efficiency, minimizing the need for cooling, minimize magnetic flux leakage and create a robust design for industrial use.
The key components in MagComp Induction heating technology is our own Magnetic flux conductor material and the use of a special coil technology.
Magneticlux conductor
MagComp has developed the SMC concept to Soft Magnetic Mouldable Composite, SM2C. SM2C is used by MagComp as flux conductor and flux concentrator in all induction heaters. The SM2C properties that induction heating benefits from are very low eddy current/hysteresis losses, high magnetic saturation, good thermal conductivity and high mechanical strength.
Modern induction heaters
Whether heating a flat surface or a cylindrical workpiece, the flux path outside the workpiece stores high amounts of magnetic energy that sends out hazardous electromagnetic fields, decreases the power factor and creates excess losses. This is a common problem related to many electromagnetic components and are usually solved with laminated iron to close the field lines. Due to the high frequency currents of induction heaters, laminated magnetic steel would be heated in the same way as the workpiece. Instead, electrically non-conductive SMC can be used to close the flux lines and thus reducing the stored magnetic energy.
MagComp has taken it further and is using its unique SM2C material to surround the induction coil and close the magnetic circuit. The SM2C is used for several reasons; to improve the efficiency of the heating system and power factor of the heating coil, also to reduce stray magnetic fields and to focus the heat (magnetic field) where it is desired in the workpiece.
Thermal management
One important factor to create a highly efficient and robust industrial induction heating system is thermal management. MagComp heaters are always built in a casing that also includes various thermal barriers as well as cooling solutions for the small portion of energy that must be taken away to keep the system operational over time. MagComp also has introduced thermal control points in the system that is monitored by the control system to ensure best performance.
Simulation
Precise simulations are very useful when designing heating inductors since different geometries, different materials etc. can easily be studied. Depending on the complexity of the model, either pure electromagnetic, steady-state properties are investigated, or the power dissipation can be used as the source to a coupled, transient, thermodynamic simulation.
Simulation of the complete system using various simulation tools, is also very useful for understanding the specific system components and to be able to optimize the system. MagComp have models to simulate the complete system and to calculate the specification and performance of each system component.
MagComp has developed tools for verifying simulation results and have extensive knowledge in the performance of the induction heating system. The correlation between simulations and the measured results is very good and therefore MagComp uses simulation for all customer specific system designs.
