Which type of dc armature winding requires equalizer rings?
Certain "Lap" wound armatures.
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.
What is lap winding?
The lap winding is used in dc generators designed for high-current application
The two winding of a transformer are inductively linked?
lap winding is most suitable for
What is parallel path in dc machine?
This describes the way the machine's armature conductors are connected relative to each other and to the number of poles. The two basic ways of connecting these conductors are called 'lap' and 'wave', but it gets more complicated, because these, in turn, can be connected 'simplex', 'duplex', 'triplex', etc.For lap windings, if there are p poles, then for:simplex: pduplex: 2ptriplex: 3petc.For wave windings, the number of parallel paths are:simplex: 1 x 2duplex: 2 x 2triplex: 3x 2etc.So, for a triplex lap winding machine with six poles, the number of parallel paths will be: 3p =3 x 6 = 18 parallel paths.

Example of transformer lap winding diagram?
'Lap windings' apply to motors, not transformers.
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 the advantage and disadvantage of wave winding?
Advantage: Wave winding provides a higher voltage output compared to lap winding with the same number of turns in the armature. This winding type also allows for better cooling due to the interleaved nature of the winding. Disadvantage: Wave winding is more complex to construct and repair compared to lap winding. It also requires more insulation material between the turns, which can increase the overall size of the winding.
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.
What is lap length for welding in reinforced bar?
The lap length for welding a reinforced bar will depend on the size of the bar that is being welded. If the bars are different diameters when lapped, the lap length should be calculated using the lesser diameter.
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.
