In lap winding, the number of brushes is always_____________?
Correct answer: B. same as the number of poles
- A. double the number of poles
- B. same as the number of poles
- C. half the number of poles
- D. two
Explanation
In a simplex lap winding, the number of parallel paths is equal to the number of poles, so one brush is normally provided for each pole. This gives the required current collection and equalizes the parallel armature paths.
