High Temp 0.210x0.210mm Enameled Rectangular Copper Wire Class 220 For Robot Motor

Our 0.210*0.210mm enameled rectangular copper wire is specially developed for high-performance robot joint motors. Different from ordinary round enameled wire, this flat rectangular wire greatly improves motor slot fill factor up to over 90%, effectively boosting motor power density and running stability. We provide complete matching solutions with diversified insulation materials and temperature resistance grades to meet different high-precision motor working environment demands.

1. Super High Slot Fill Factor: Optimized rectangular size design, slot fill factor reaches more than 90%, maximizing motor internal space utilization, obvious improvement of motor overall efficiency.
2. Lower Resistance Loss:Compared with round enameled wires, this rectangular structure effectively reduces resistance loss and improves energy utilization.
3. Excellent Heat Dissipation:Arranged like bricks, the tight structure minimizes air gaps and accelerates heat conduction, solving heat accumulation problems efficiently.
4. Three-field Integrated Optimization:Comprehensively upgrade the performance of motor electric field, magnetic field and thermal field for all-round improvement.
5. Full Range Temperature Resistance Option: Available in Class 155℃ / Class 180℃ / Class 200℃ / Class 220℃, with Polyurethane, Polyesterimide and Polyamide-imide insulation for choices.,covering conventional working conditions and high-temperature harsh working scenarios of robot motors.
6. Complete Authoritative Certifications: Passed UL, RoHS, ISO, IATF automotive-grade certification, fully compliant with European and American import standards, no customs clearance risks.
