What are lap and wave winding?
Wave Winding. The lap winding can be defined as a coil which can be lap back toward the succeeding coil. The wave winding can be defined as the loop of the winding can form the signal shape. The connection of the lap winding is, the armature coil end is connected to the nearby section on the commutators.
What is a wave winding?
Definition of wave winding : an armature winding in which the coils are laid in two layers and follow each other on the surface of the armature in the form of waves with the coils being so connected in series that there are only two paths for the flow of current whatever the number of poles in the machine.
What is the use of lap winding?
Lap Winding is a form of two-layer winding for electric machines in which each coil is connected in series with the one adjacent to it. lap winding is used for high current and low voltage machines.
What is lap winding formula?
A winding in which the number of the parallel paths between the brushes is twice the number of poles is called duplex lap winding. P = number of poles. YB = Back pitch. YF = Front pitch. YC = Commutator pitch.
Why lap winding is used in DC generator?
Lap winding: In lap winding, the number of parallel paths (A) is the same as the number of brushes and poles. This winding is mainly used for low voltage and high current applications….4.6.
| Lap Winding | Wave Winding |
|---|---|
| The efficiency of the lap winding is less | The efficiency of the wave winding is high. |
Which is the most used winding?
copper
The most commonly used material for winding is copper.
What is the name of winding?
Winding is a common name for an electromagnetic coil. Winding may also refer to: People with the name Winding: Alberte Winding (born 1963), Danish singer and actress.
What is the difference between simplex and duplex lap winding?
A winding in which the number of parallel path between the brushes is equal to the number of poles is called simplex lap winding. A winding in which the number of parallel path between the brushes is twice the number of poles is called duplex lap winding.
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.
