## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the purpose of the eccentric weight in this rotor?
**A**: The eccentric weight creates an off-center mass that generates centrifugal force during rotation, producing controlled vibration for applications like vibrating motors, feeders, or compactors in electrical equipment.

### Q: Why is tungsten alloy used for the weight component?
**A**: Tungsten alloy provides high density in a compact size, allowing for maximum centrifugal force generation with minimal weight size. This improves efficiency and vibration intensity while maintaining structural integrity.

### Q: What are the main applications for this rotor in electrical manufacturing?
**A**: This rotor is used in vibration motors for material handling equipment, compactors, feeders, sorting systems, and any electrical device requiring controlled mechanical vibration for operation or material movement.
