Shanxi Jurun Technology Co., Ltd., located in the industrial hub of Taiyuan, Shanxi, China, specializes in manufacturing precision-engineered cold-drawn pure iron wire specifically for electric motor rotor cores. Our wire ensures optimal magnetic flux efficiency in motor assemblies, directly enhancing energy conversion and operational reliability. With vertically controlled production processes, we deliver material consistency critical for high-speed rotor applications. The advanced cold-drawing technique employed at our Taiyuan facility guarantees dimensional tolerances within ±0.01mm, making it ideal for automated assembly lines.
The core benefits of our pure iron wire include:
- Superior Magnetic Performance: 99.5%+ purity minimizes eddy current losses
- Dimensional Precision: Tight diameter control enables seamless lamination stacking
- Enhanced Durability: Cold-working increases tensile strength while maintaining flexibility
- Surface Integrity: Oxide-free surface prevents inter-lamination short circuits
Technical specifications vary based on application requirements:
| Parameter | Standard Range | Custom Options |
|---|---|---|
| Diameter | 0.5mm - 2.0mm | 0.2mm - 5.0mm |
| Roundness Tolerance | ≤0.015mm | ≤0.008mm |
| Resistivity | 0.1 μΩ·m | N/A |
Production advantages include batch traceability through laser marking and in-process diameter monitoring using optical measurement systems. For motor manufacturers, this translates to 15-20% reduction in rotor imbalance issues and extended service life under high-temperature operating conditions.
Leveraging our Shanxi-based manufacturing infrastructure, Jurun Technology maintains strict metallurgical control from raw material sourcing to final annealing. Our ISO-compliant facility (certification available upon request) ensures every coil meets rigorous international motor manufacturing standards. With over 300 successful rotor core integrations documented, we offer technical consultation to optimize wire selection for your specific motor design. Contact our Taiyuan engineering team today for customized solutions that enhance your motor efficiency.
