Motor Winding Wire for Industrial Applications

The enameled wire for motors has two main tasks. It must conduct electricity in the longitudinal direction and insulate in the transverse direction. Signi specializes in the production of enameled wire for industrial motors. Its products are widely used in DC motors, AC motors, single-phase motors, three-phase motors, progressive motors, servo motors, explosion-proof motors, high-temperature-resistant motors and other special motors.

Signi enameled motor winding wire production capacity

• The raw material is 9.5mm high-quality metal wire, which is processed into the required wire diameter through a wire drawing die.
• The mold coating machine ensures that the paint film thickness is uniform and stable, and the voltage and insulation properties are consistent; it can apply up to three different electrical insulation coatings with a thickness of 60-450 μm; the paint film is high temperature resistant and will not crack at 350°C.
• Advanced infrared oven technology strictly controls time and temperature to ensure uniform curing of insulation materials and ensure performance and stability.
• The application of patented lubricating oil coating makes the automatic variable speed winding machine operate more smoothly and reduces friction.
• The high-speed precision winding machine can precisely control the winding tension, speed and angle; providing wire coil types and sizes from 5kg to 200kg.
• According to customer requirements, we provide test reports such as raw material pole material certificate, finished enameled wire paint film thickness, dielectric loss, breakdown test, elongation, elasticity test, etc.
• The maximum weight of wooden wire reels can reach 200kg; cylindrical, conical or other customized models are available; the wire reels are well packaged, moisture-proof and shock-proof.
