- **Caution**: 
- **Caution**: 

### Q: What materials are used in stator construction?
**A**: Stators are typically constructed from electrical steel laminations for the core, copper wire for windings, insulation materials, and structural steel or aluminum for the housing/frame.

### Q: What is the function of a stator in an electric motor?
**A**: The stator is the stationary part of an electric motor that generates a rotating magnetic field when energized, which interacts with the rotor to produce mechanical rotation.

### Q: What are the main components of a stator assembly?
**A**: The main components include the stator core (made of laminated electrical steel), stator windings (copper wire coils), insulation system, and stator frame/housing for structural support.
