The heated parts of an electrical machine dissipate heat into their surroundings by which of the following modes of heat dissipation ?
Correct answer: D. All of the above
- A. Conduction
- B. Convection
- C. Radiation
- D. All of the above
Explanation
Heat can leave an electrical machine by conduction through solid parts, convection to the surrounding fluid and radiation from exposed surfaces. All three mechanisms normally contribute to the total heat dissipation.
