Maintaining High-Temperature (HT) motors used in cement plants involves the following steps:

1. Regular inspections: Inspect the motor for any signs of wear, damage, or loose parts. Pay close attention to the bearings, windings, and enclosure.
2. Lubrication: Ensure that the bearings are properly lubricated to reduce friction and heat buildup. Use a high-quality grease specifically designed for use in high-temperature applications.
3. Cleaning: Keep the motor clean by removing any debris or foreign material from the enclosure. Regular cleaning will help prevent overheating and extend the life of the motor.
4. Testing: Perform routine tests to verify the motor's efficiency, winding resistance, insulation resistance, and overall condition. These tests can help identify potential issues before they become major problems.
5. Repairs and Replacements: If necessary, make repairs or replace worn-out components as needed to keep the motor in good working order.

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
