Servo Motor Coils are precision-wound electromagnetic components used in servo motors to support accurate torque output, fast response, and stable motion control. These coils are widely used in industrial automation, robotics, CNC equipment, medical devices, packaging machinery, and other systems that require precise positioning and reliable motor performance.

WIRESUN manufactures custom servo motor coils according to customer drawings, samples, or electrical specifications, supporting different wire materials, winding structures, coil shapes, resistance values, inductance requirements, and insulation grades. With CNC precision winding equipment, controlled wire tension, and strict batch inspection, WIRESUN supports prototype development, sample validation, and mass production for OEM/ODM servo motor coil projects.

Our standard MOQ is 500 pcs for most coil types. For first-time customers or prototype evaluation, we accept small trial orders of 10-50 pcs. MOQ may vary by product complexity. Contact us for a specific quote.

Yes. Samples are available within 5-7 business days after engineering confirmation. A nominal sample fee applies, which is credited toward your first mass production order.

You can email drawings such as PDF, DWG, or STEP files, or fill out our inquiry form. If you do not have drawings, a written description or physical sample is also acceptable.

We can wind wire as fine as 0.01mm using Zongheng CNC precision winding machines with automated tension control.

Yes. Our special-shaped coil series handles non-circular and irregular geometries. Submit your drawings and our engineering team will assess feasibility.

Standard options include bare copper wire, enameled copper wire, and Litz wire. Custom alloy or coated wire options are available on request.

Yes. Provide your target inductance, frequency, and DC resistance requirements, and we will calculate and wind to specification.

WIRESUN is ISO 9001 certified. Products can ship with test reports and COA. Third-party inspection can be arranged upon request.

All coils are wound on CNC machines with precision control. Each production batch undergoes electrical testing, including inductance, DCR, and impedance checks.

Standard documentation includes packing list, commercial invoice, Certificate of Analysis, and electrical test report. RoHS/REACH documents are available upon request.

We ship worldwide. Regular destinations include Southeast Asia, Europe, the Americas, the Middle East, and Russia. Express and sea freight options are available.

Standard terms are 30% T/T deposit upon order confirmation and 70% balance before shipment. L/C is accepted for larger orders, and Western Union is available for sample fees.

Standard products usually take 15-20 business days. Complex custom coils generally take 20-30 business days. Final lead time is confirmed at quotation stage.
