セルコ Product Lineup

In the era of EV (electric vehicles), coil technology aims to maximize the packing density while keeping costs down. Instead of using rectangular wire, we compress and shape round wire to fill the teeth of the motor core, and by using aluminum for the wire, we eliminate the performance gap with copper wire at high packing densities, ensuring compactness, lightweight, and high performance. This new approach will significantly advance motor technology in the future. Our coils demonstrate performance that changes conventional wisdom through compression, shaping, and bending technologies. We achieve miniaturization and lightweight products, the formation of highly efficient coreless motors, and mass production of extremely precise coils. We contribute to the differentiation of your products. 【Three Technologies for Differentiation】 ■ Compression and Shaping Technology: Enables coils to be inserted into the motor core without gaps. ■ Coil Bending Technology: Allows for the formation of highly efficient coreless motors. ■ Coil Winding Technology: Capable of minimizing variations in resistance and inductance to the extreme. We are providing case study materials. *For more details, please refer to the PDF document or feel free to contact us.

• Inductor Coil

Our company provides high-density coils for EV vehicles and precision machinery, utilizing manufacturing methods such as bending, compressing, molding, and others that were previously unimagined in the industry. When it comes to packing density (the ratio of wire within the coil), you might think of flat wire, but our high-density coils exceed the packing density of flat wire. 【Features】 ■ Achieves a packing density of 89% to 93% by compressing high-density coils into round wire ■ Allows for flexible design by bending high-density coils ■ Molds high-density coils to pack them without any gaps ■ Integrates and seals high-density coils to achieve high-precision dimensions *For more details, please download the PDF or feel free to contact us.

• Inductor Coil

We handle "high-density compression molded coils," which are made by compressing round wire coils and packing as much wire as possible into a designated core. When used as an SR motor, it eliminates the need for magnets, resulting in a motor that is inexpensive, small, high-performing, and has excellent heat dissipation. 【Features】 ■ Round wire is cheaper than flat wire and can be compression molded without damaging the insulation. ■ It is possible to pack as much wire as possible into the gaps of the core (high packing density), achieving space-saving and high performance. ■ Because it is molded, we can provide uniform coils in various shapes, stabilizing the magnetic force. *For more details, please download the PDF or feel free to contact us.
