Question

For generating large currents on D.C. generators which winding is generally preferred?
1) Progressive wave winding 2) Lap winding
3) Retrogressive wave winding 4) Current depends on design

Answer 1

2)lap winding is the right answer.

Answer 2

Lap winding is generally preferred for generating large currents on DC generators. (Option 2)

• In lap windings, the successive coils are positioned in such a way that they overlap each other.
• Since they lap back with each succeeding coil, they are called lap winding.
• These winding are designed in such a way that they have many parallel paths due to the overlapping.
• These parallel paths make them suitable for generating large DC currents.
• Therefore, lap winding is also known as parallel winding.
