Stator Stamping for Rail Transportation Motor
- Precision Stamping Process: Utilizes integrated automatic steering manipulators with gantry-type lines for 90° turning stamping.
- High Dimensional Accuracy: Ensures consistent stator geometry for stable magnetic flux and balance.
- Enhanced Magnetic Efficiency: Silicon steel sheets reduce core losses and improve power conversion.
- Size Range: Available from 300 mm to 550 mm, adaptable for various rail motor designs.
- High Mechanical Strength: Built to withstand vibration, impact, and heavy-duty traction conditions.
