Optimization was achieved through 3D thermal analysis and inversion mechanism simulation.
Highly efficient electromagnet has been developed by using a computer simulation with 3D magnetic field analysis
so that AC and DC electromagnets have the same appearance. (FJ-B06, B09, and B12 types)
Developing DC electromagnet
Developing compact and highly efficient electromagnet by using permanent magnet and making use of coil energy
The DC electromagnet can be directly powered by 2.4 W through semiconductor output by minimizing the leaked magnetic flux, distributing
optimized magnetic flux, and satisfying demand for both less loss and smaller size.

3D thermal analysis simulation
The thermal element is explored through 3D thermal imaging analysis.
With the high efficiency heating and the stable bend of the bimetallic
strips, the product can be further miniaturized.
New inversion mechanism
The reversing mechanisms can be miniaturized and their stable
operation features can be achieved through the simulation
experiments of reversing mechanisms.
Developing AC electromagnet
A compact electromagnet has been developed by optimizing the sectional area of each iron core part and excluding magnetic flux saturation and
not having a wasteful shape
The iron-core-fixing rivets are optimally arranged in order to remove the impact on magnetic flux route and the rivets can reduce eddy current loss.
This optimal design makes it possible to develop an energy saving electromagnet
that has 4.5 VA of electromagnetic capacity.
