As a specialized manufacturer based in Taiyuan, Shanxi, Shanxi Jurun Technology Co., Ltd. produces premium DT4 forged round bars engineered specifically for electric motor rotor applications. Our products deliver exceptional magnetic performance and structural integrity, directly impacting motor efficiency and longevity. With precise control over material properties and forging processes, we provide rotor materials that meet stringent industry requirements while optimizing manufacturing outcomes.
Core Technical Advantages:
- Material Excellence: DT4 electrical steel composition ensures optimal magnetic flux density with minimal core loss
- Superior Forging Process: Hot forging creates directional grain flow that enhances mechanical strength
- Consistent Quality: Rigorous process controls maintain uniform material properties throughout each bar
Performance Specifications:
| Property | Value Range | Benefit |
| Electrical Resistivity | 0.45-0.50 μΩ·m | Reduced eddy current losses |
| Magnetic Flux Density | 1.6-1.8 T | Higher motor torque output |
| Core Loss (50Hz) | ≤4.5 W/kg | Improved energy efficiency |
The forging process eliminates internal voids and porosity, creating rotors with balanced performance characteristics. Our bars maintain dimensional stability during high-speed machining operations, reducing scrap rates in production. Custom diameters and lengths are available to match specific rotor designs, minimizing material waste.
Manufacturing Advantages:
- Predictable machining behavior reduces tool wear
- Consistent magnetic properties across production batches
- Lower hysteresis losses increase motor efficiency
- Reduced vibration in final motor applications
