Which of the following losses is not dissipated by the stator core surface in a synchronous motor?
Correct answer: D. Windage losses
- A. Eddy current losses in the conductors
- B. Iron losses in the stator
- C. Copper losses in the slot portion of the conductors
- D. Windage losses
- E. None of the above
Explanation
Windage loss is caused by air friction from the rotating rotor and is not dissipated by the stator core surface. Stator iron, conductor eddy-current, and slot copper losses are associated with stationary stator parts.
