【Shaped Wire】Ultra-Fine Rectangular Enameled Copper Wire for Micro Linear Motors

Pioneering Ultra-Fine Rectangular Wire Technology

HUAYE continues to push the limits of precision magnet wire manufacturing.

Following the successful mass production of the world's first 0.065 * 0.065 mm self-bonding rectangular enameled copper wire, we have achieved another technological milestone with the development of an even finer 0.050 * 0.050 mm ultra-fine rectangular enameled copper wire, further expanding the possibilities for next-generation micro motor applications.

Through proprietary die design and precision manufacturing, the corner radius (R) is controlled below 0.010 mm, with our exclusive tooling achieving an exceptional R0.008 mm, ensuring outstanding dimensional accuracy and consistency.

Technical Advantages

Compared with conventional round enameled wire, HUAYE's ultra-fine rectangular wire provides a significantly higher conductor fill factor, delivering:

• Higher motor efficiency and power density
• Improved heat dissipation
• Enhanced operational stability
• Smaller, lighter motor designs
• Lower overall manufacturing costs
• Excellent dimensional consistency for precision winding

Applications

HUAYE's ultra-fine rectangular wire is widely used in micro linear motor coils for smartphones, smart wearable devices, and other compact consumer electronics, replacing conventional round enameled copper wire to achieve higher performance within increasingly limited installation space.
