Any even number of conductors
Any odd number of conductors
That even number which is exact multiple of poles + 2
That even number which is exact multiple of poles
Answer is Right!
Answer is Wrong!
The correct answer is: A. Any even number of conductors.
A lap winding is a type of winding used in electrical machines. It is composed of a series of conductors that are connected in parallel. The number of conductors in a lap winding must be an even number, so that the ends of the conductors can be connected to the commutator.
A lap winding is more efficient than a wave winding, because it has less copper loss. However, it is more difficult to manufacture, because the conductors must be individually insulated.
Here is a brief explanation of each option:
- Option A: Any even number of conductors. This is the correct answer, as explained above.
- Option B: Any odd number of conductors. This is incorrect, as the number of conductors in a lap winding must be an even number.
- Option C: That even number which is exact multiple of poles + 2. This is incorrect, as the number of conductors in a lap winding does not need to be a multiple of the number of poles.
- Option D: That even number which is exact multiple of poles. This is incorrect, as the number of conductors in a lap winding does not need to be a multiple of the number of poles.
