In the overhang of the stator of electric machines like motors and generators, the conductors or winding ends extending beyond the core (the overhang) should be properly treated to ensure efficient operation, safety, and durability. Here are key steps and considerations:
1. Insulation: Ensure that the conductors in the overhang are adequately insulated from each other and from the stator body to prevent electrical shorts. This involves using high-quality insulation materials designed for high electrical stress and thermal conditions.
2. Securing and Support: The conductors need to be securely supported and positioned to prevent movement that might be caused by electromagnetic forces during operation or mechanical vibrations. This often involves using wedges, ties, or resin encapsulation to hold the overhang firmly in place.
3. Cooling: Adequate cooling mechanisms should be in place to remove the heat generated in the overhang area. Depending on the design and size of the machine, this may involve air cooling (forced or natural), liquid cooling, or a combination of methods. Ensuring good airflow or coolant flow around the overhang is crucial for maintaining operational temperatures within safe limits.
4. Vibration Damping: Implementing measures to dampen vibrations can help in reducing stress and fatigue on the winding overhang. This can extend the service life of the windings and prevent mechanical failures.
5. Protection Against Environmental Factors: Consideration should be given to protecting the overhang from environmental factors such as moisture, dust
Answer: a
Explanation: The conductors in the overhang of the stator must be braced. Bracing is the process of raising the mechanical strength of the conductors.
