Rotor Stamping for Rail Transportation Motor
- Precision Stamping Process: Utilizes integrated automatic steering manipulators for 90-degree turning operations.
- High Dimensional Accuracy: Guarantees rotor consistency and balance for high-speed rail applications.
- Improved Magnetic Efficiency: Silicon steel sheets enhance energy conversion and reduce core loss.
- Size Range Flexibility: Covers rotor diameters from 210 mm to 400 mm to fit multiple traction motor models.
- High Mechanical Strength: Withstands high centrifugal forces and vibration during prolonged rail operation.
