Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Lap and Wave Winding. The winding wounded at the armature is called armature winding. The armature winding is used to the conversion of power for generator mechanical power is transformed in electrical power and for the motor electrical energy is transformed in mechanical power. There are 2 common types of armature windings first one is lap windings and the second one is wave winding.
The basic difference between these two windings is that in lap winding end of every coil is attached to the neighboring point and in wave winding the endpoint of winding is connected with the point at some distance. In today’s post, we will have a detailed look at both lap and wave winding with a detailed comparison of them to find their differences. So let’s get started with Difference Between Lap and Wave Winding.
Difference Between Lap and Wave Winding
Lap Winding
- The connection of two winding is such that the end terminal of the first winding is linked to the initial point of neighboring winding is called lap winding.
- This winding provides the same current paths as poles exist in the machine.
- The main types of lap winding are simplex, and duplex.
- It has several brushes equal to parallel current paths.
- The simplex winding has a parallel path same to poles.
- Lap windings of multiplex type are used for high-current applications.
- Lap winding is employed for large current and less voltage applications.
- It is more expensive than wave winding since more conductor is used
Simplex Lap Winding
- This winding has several parallel paths equal to the number of poles.
Duplex Lap Winding
- In these windings, number of the parallel paths is 2 times the poles of machines.
What is Wave Winding
- In these windings, the coil is not linked to neighboring winding like lap winding.
- Its configuration is such that winding it passes from every north and south pole of the machine.
- This winding called series due to the sequence structure
- There is just a need for 2 brushes in this winding
- It has only two parallel paths
- Using Z/2 formula number of the conductor can be determined
- Its common types are progressive and regressive wave winding
- These windings need dummy winding to fulfill the requirements of the conductor used in this winding
What is meant by wave winding?
- The armature windings have winding in a 2 layers configuration and follow to each other on the armature surface in a wave-like design with coils connected in series combination and have two paths for current flow.
What are the advantages of wave winding?
- It provides spark-free commutation since has 2 parallel paths independent of machine poles.
What is the use of lap winding?
- For lap winding, the number of parallel paths is the same as the poles and brushes number. This winding is used for low-voltage and high-current projects.
What is lap winding best suited for?
- It is the two-layer winding type where each coil is connected with a series to neighboring winding. It is used for high-current and low-voltage machines.
Why is wave winding used for high voltage?
- For a certain number of poles and armature conductors, it has high EMF as compared to lap winding. So wave winding is used for high voltage and low current devices. It is best for small generators circuit that has ratings in the range of 500-600V.
What is the pitch of a lap winding?
- The resultant pith is equal to the difference between back and front pitches. For wave winding resultant pitch is equal to the sum of the back pitch and front pitch.
Why is a 2 in wave winding?
- The number of parallel paths is two for wave winding so it has two brushes.
Is lap winding used for high current?
- Lap winding is best to use for high-current and low-voltage generator circuits and wave winding is best for high-voltage and low-current generators. Since lap winding has more current and has a high parallel path as compared to wave winding.
What is duplex lap winding?
- The winding where the number of parallel paths between brushes is double than number of poles is called duplex lap winding.
