In case of a 4 pole D.C. generator provided with a two layer lap winding with sixteen coils, the pole pitch will be
A. 4
B. 8
C. 16
D. 32
Answer: Option B
Solution (By Examveda Team)
Here's an explanation to help you understand the question:First, let's define pole pitch. It is the distance between the center of two adjacent poles in a DC generator.
To calculate the pole pitch, we need to know the total number of slots or coil sides around the armature and the number of poles.
We are given:
* Number of poles (P) = 4
* Number of coils = 16
* Two layer winding means each coil has two coil sides.
Since it's a two-layer winding, the total number of coil sides is twice the number of coils: 16 coils * 2 coil sides/coil = 32 coil sides.
In a lap winding, the number of coil sides equals the number of armature conductors or slots. So, we have 32 slots.
The formula for pole pitch is:
Pole Pitch = (Total Number of Slots) / (Number of Poles)
So, Pole Pitch = 32 / 4 = 8
Therefore, the correct answer is Option B: 8.
This Question Belongs to Electrical Engineering >> D.C. Generators
Its duble layer winding so no of slots would be 16. Ans=4
2 conductor=1 coil
For single layer
1 slots keep 1 conductor means 1/2 coil
For double layer
1 slots keep 2 conductor means 1 coil
16 slots keep 32 conductor means 16 coil
Pole pitch =slots/pole
Hence 16/4= 4 answer is correct
Ans should be 4. In single layer wnding, Coil=Slots=16
Lap winding A=P=4
Pole pitch=Slots/poles=16/4= 4ans
POLE PITCH= NO: OF CONDUCTORS/ NO: OF POLES
= 32 / 4
POLE PITCH = 8 ANSWER
NO: OF CONDUCTORS = NO: OF COIL * LAYER
= 16 * 2 = 32
And 4 .in case of double layer wind no of coil=no of slot.
Pitch fac=slot per pole
=16/4=4
Pp = 2*no of conductor/pole
