Closed windings
Open windings
Either of the above
None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: A. Closed windings
Closed windings are always double layer type. This is because the windings must be able to withstand the high magnetic flux density that is generated in the stator core. The double layer winding provides a more efficient way to distribute the flux density, and it also helps to reduce the leakage inductance of the stator winding.
Open windings are not always double layer type. They can be single layer or double layer, depending on the design of the machine. Single layer windings are less efficient than double layer windings, but they are simpler to manufacture.
Neither of the above is not the correct answer.
