Why lap winding is used for low voltage and high current?
Lap winding is suitable for high current and low voltage generators while wave windings is for high voltage and low current generators, it is because lap winding carries more current as it has more parallel paths than wave winding.
Which of the winding is used for high current low voltage?
Lap winding
Lap winding: This winding is mainly used for low voltage and high current applications.
Why lap winding are used in large multipolar dc generators?
In multipolar machines, for a given number of poles (P) and armature conductors (Z), a wave winding has a higher terminal voltage than a lap winding because it has more conductors in series. On the other hand, the lap winding carries more current than a wave winding because it has more parallel paths.
Which winding in dc generator is preferred for generating large current?
2)lap winding is the right answer.
Which type of connection make in lap winding?
Comparison Chart
| Basis For Comparison | Lap Winding |
|---|---|
| Connection | The end of the armature coil is connected to an adjacent segment on the commutators. |
| Parallel Path | The numbers of parallel path are equal to the total of number poles. |
| Other Name | Parallel Winding or Mulitiple Winding |
| EMF | Less |
Why wave winding is used for high voltage?
The conductors in each of the two parallel paths distributed around the armature in the entire circumference. For a given number of poles and armature conductors, it gives more emf than that of lap winding. Hence wave winding is used in high voltage and low current machines.
What is the efficiency of dc motor at maximum power?
Explanation: For getting maximum power, derivative of power with respect to current is equal to 0. This is practically impossible to achieve as, current required is much more than its normal rated value. Large heat will be produced in a machine and efficiency of motor will be less than 50 \%.
What are the different types of lap windings in DC machines?
Here we are going to discuss l ap windings and the two main types of lap windings in DC machines. These are known as Simplex Lap Windings and Duplex Lap Windings. What is a Lap Winding?
Why lap winding is preferred for high current rating generators?
Large number of parallel paths indicate high current capacity machine hence lap winding is preferred for high current rating generators. In this type of connection, winding always travels ahead avoiding overlapping. It travel like a progressive wave hence called wave winding.
Why must the back pitch of an electric motor be odd?
The back pitch and front pitch must be odd. Y R is even because it is the difference between two odd numbers. This winding is necessarily required for large current applications because it has more parallel paths. It is suitable for low voltage and high current generators. It gives less emf compared to wave winding.
How are conductors joined in lap winding?
In lap winding, the conductors are joined in such a way that their parallel paths and poles are equal in number. The end of each armature coil is connected to the adjacent segment on the commutator.
