What are advantages of lap winding and wave winding?
Wave winding is used for high voltage and low power machine. It is generally used for machines having power rating less than 50 kW. The basic thumb rule is that, lap winding is used where the machine requires low voltage but more current whereas wave winding is suited where current is low but voltage is high.
What is a lap winding?
Definition of lap winding : a drum winding for generator and motor armatures in which each coil or set of windings overlaps the next so that there are as many armature paths as there are field-magnet poles.
What are the advantages of lap winding?
Disadvantages of Lap Winding of conductors for giving the same emf, which results in high winding cost. It has less efficient utilization of space in the armature slots.
What is a wave winding used for?
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 no of the parallel path is equal to the total of no of poles | The no of parallel paths is equal to two. |
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.
Which winding is used for High Voltage?
4.6
| Lap Winding | Wave Winding |
|---|---|
| The emf of lap winding is less | The emf of wave winding is more. |
| The efficiency of the lap winding is less | The efficiency of the wave winding is high. |
| The lap winding is used for high current, low voltage machines | The applications of wave winding include low current and high voltage machines. |
What are different types of windings?
The lap winding applications mainly involve in high current and low voltage machines. These windings are categorized into three type’s namely simplex, duplex and triplex type winding.
Why wave winding is suitable for dc generator?
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. This winding is suitable for small generators circuit with a voltage rating of 500-600V. Current flowing through each conductor.
What are the types of winding?
The motor winding types are two types which include the following.
- Stator Winding.
- Rotor winding.
What is simplex type lap and wave winding?
Simplex Lap Winding: In simplex lap winding, the terminating end of one coil is joined to the commutator segment and the starting end of the next coil is placed under the same pole. Also, the number of parallel paths is similar to the number of poles of the windings.
Why wave winding Has high voltage?
Why lap winding is used in DC machine?
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. |
What is the difference between lap windings and wave windings?
Key Differences Between Lap and Wave Winding. The simplex and duplex are the types of lap windings. In simplex winding, the number of parallel paths is equal to the pole, in duplex winding the pole is twice to that of a parallel path, whereas the progressive and the retrogressive are the types of the wave windings.
What is wavewave connected winding?
Wave connected winding is required for high voltage but low current rating machines. Since emf generated in DC machine = (ØZPn / a) where P,n and ‘a’ are number of poles, speed in rps and number of parallel path. But in lap winding, number of parallel path ‘a’ = P; therefore, the emf generated in lap winding = ØZn.
What is the difference between wave winding and armature winding?
The number of brushes is equal to the number of parallel paths. The wave winding is mainly used in high voltage, low current machines. If after passing one round, the armature winding falls into a slot to the left of its initial point, then the winding is said to be retrogressive.
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.
