To maintain the end frame's efficiency, follow these steps:
Regularly inspect the end frame for signs of wear or deformation, and promptly address any issues.
Ensure all vents and cooling fins are clean and unobstructed to facilitate effective heat dissipation.
Periodically check the slip ring's internal components—the brushes, rings, and bearings—and replace them when required.
If the application is in a harsh environment, make sure the end frame's protective coatings or treatments (e.g., anti-corrosion) are intact and maintained.
