Lap winding and wave winding?
Both lap winding and wave winding are found in the use of DC generators. The main difference is as follows: lap winding is high current, low voltage, and wave winding is low current, high voltage.
The two winding of a transformer are inductively linked?
lap winding is most suitable for
Which type of dc armature winding requires equalizer rings?
Certain "Lap" wound armatures.
What is equalizer bar ring in lap winding?
The function of equalizer rings is to avoid un equal distribution of current at the brushes,there by helping to get sparkless commutation- by rizwan ahmad
What is LV winding of a transformer?
For a step-down transformer, its secondary winding will be the LV winding. For a step-up transformer, its primary winding will be its LV winding.

Example of transformer lap winding diagram?
'Lap windings' apply to motors, not transformers.
What is frog leg winding and its application?
a composite winding consisting of one lap winding and one wave winding, placed in the same slots and connected to the same commutator
Why use lap winding for highy current and low voltage?
because we know that for lap winding P=A. so no of poles=no of parallal paths. so as the no of parallal paths increases ,the current will be also increases.....so total voltage will be decreases....for this we refer lap winding for high current and low voltage.
What is the disadvantage of lap winding?
It is always strong quite weak
what is Lap winding and wave winding?
The ends of lap windings are connected to adjacent segments of the machine's commutator, whereas wave windingsare connected between segments that are some distance apart. This results in lap windings having 2p parallel paths, where p represents the number of pole pairs; whereas a wave winding has just two parallel paths.
What are types of windings in low voltag windings?
to achieve high voltage Wave type winding is used...... For high current Lap winding is used.
Which type of dc armature winding requires equalizer rings?
Certain "Lap" wound armatures.
In motor winding what is the difference between a lap winding and a wave winding?
When electricians and electrical engineers/repairmen are called upon to assess troubles in generators and motors, they often rewind different types of these machines. There are two families of armature (closed-circuit) windings: lap winding and wave winding, described by the commutator pitch used for winding. In mechanical terms, armature windings consist of coils connected to a commutator in Read more....direct-current machines; or coils are connected together in alternating-current machines to form groups or series.Lap winding, also called parallel or multiple winding, is the process of winding elements or coils lapping back when wound on armature cores. Lap circuits are connected in parallel between brushes. The front and back pitches are odd with opposite signs. Winding pitch equals the algebraic sum of the front and back pitches. The end of a coil is connected to the commutator and the start of the next coil under the same two poles. Single-lap windings always have the same number of current paths as field poles while double-lap windings have twice as many current paths as field poles. Triple-lap windings have three times the number of current paths as field poles.The zig-zag or wavy path of winding through slots of armatures defines single (two-circuit) wave windings and multiplex (series-parallel) windings. Half of the armature coils is connected in series and the other half is connected in parallel between brushes, no matter the number of poles. Winding pitch is equal to the sum of the front and back pitches, which both must be odd with the same sign. The end of a coil is joined to the armature and the beginning of another under the next two poles. A single-wave winding has two current paths between brush sets. The double-wave winding has four current paths between brush sets; and the triple-wave winding has six current paths.Wave winding is used mostly in small and medium sized machines (500-600 volts) for keeping the number of coils as small as possible. Applications requiring high voltages at low currents use wave windings while lap windings are used for lower voltage, higher current applications. Wave windings, for a given number of poles and armature conductors, give more emf (electric and magnetic fields) than lap windings.Examples of suitable symmetrical armature windings for DC-machines with different poles are: for two-pole machines, two-circuit lap winding is preferred over wave winding; for four-pole machines, two-circuit wave winding or four-circuit lap winding is suggested. Six-pole machines should use two-circuit wave or six-circuit lap winding since four-circuit wave winding is asymmetrical.
Dc machine having wave winding is wounded as lap winding what will be the effect on emf generated?
Emf generated=(flux*no.of parallel poles*no.of conductors*speed)/(60*no.of parallel paths) therefore, for lap wound.... no.of parallel path=no.of poles and wave wound ..... no of parallel path=2
