日東電機 List of Products and Services

Using our unique winding method at Nitto Electric Co., Ltd., we produce high-density, space-saving rectangular wire coils with our in-house winding machines! We can accommodate customer needs from small to large-scale production. In traditional rectangular wire (ribbon wire), there were various inconveniences such as "we can't do fine adjustments to wire dimensions like thickness and width in-house!" and "the unit price is high!" Our company has successfully rolled round wire into rectangular wire using our unique technology. By performing these rolling processes within the same operation as winding, we significantly contribute to the mass production of aligned wound coils and the improvement of packing density, enhancing cost performance. 【Features】 ★ The rolling process is completed within the same operation as winding. ★ Cost reduction is possible due to the thinness of the magnets. ★ Compact motor sizes are achieved due to high packing density. ★ We can accommodate prototype to mass production with lot sizes tailored to your requests. ★ Compatible with copper wire, wire diameters from 0.045 to 0.25.

Air-core coils, unlike winding coils that are wound around a bobbin or similar frame, maintain their coil shape solely with copper wire, with the wire materials bonded together. Therefore, they are often used in electronic devices that require space efficiency, compact size, and high performance. On the other hand, the material costs for the wire are generally high, and the winding machines also need to be specialized, making air-core coils more expensive compared to bobbin-wound winding coils.
