Slot Wedge for Generator Units QFSN-600-2

Slot wedges are crucial for tightly securing the stator coils in the stator slots for large generator units such as QFSN-600-2 and QFSN2-660-2.

Functions of Slot Wedges

• Coil fixation: Their main function is to prevent coil displacement or detachment during operation.
• Adjusting motor air gap: They can maintain or adjust the size of the motor air gap.
• Maintaining rotor stability: Their shape and precision have a direct impact on rotor stability.
• Improving insulation: They can act as an additional insulation layer, protecting coils from potential electrical breakdowns.
• Preventing foreign object entry: Their tight installation can prevent dust and moisture from entering the stator slots.
• Reducing noise and vibration: Proper installation helps reduce noise and vibration during motor operation.

Application of Slot Wedges

• Inside the stator slots: They are primarily installed in the generator's stator slots to secure the stator coils.
• Inside the rotor slots: In the generator's rotor slots, they are used to fix the rotor coils.
• Ventilation ducts: They can also form ventilation ducts to help cool the motor.
