## What is wave winding in DC motor?

A wave winding (also known as a series winding) is a type of armature winding. Along with a lap winding, wave windings form one of the two types of armature windings in DC machines. In a wave winding, we connect the end of one coil to the start of another coil of the same polarity.

## What is simplex type lap and wave winding?

Lap Winding : Lap winding can be of three types simplex, duplex, and triplex. In simplex lap winding, there are as many parallel paths as there are a number of field poles. The multiplex (duplex or triplex) lap windings are used where heavy currents at low voltage are necessary.

How do you do a lap winding?

The duplex lap winding is mainly used for heavy current applications. Such type of winding is obtained by placing the two similar winding on the same armature and connecting the even number commutator bars to one winding and the odd number to the second winding.

### What is the difference between lap and wave winding?

The main difference between these two is, in the lap winding, One of the major difference between them is that in a lap winding, the last part of every coil is associated with the nearby sector while in the wave winding the last part of armature coil is associated with the commutator sector at a distance apart.

### What are the uses of lap and wave windings?

The lap winding is used in low voltage, high current machines, whereas the wave winding is used in high voltage, low current machines.

What are the difference between lap and wave winding?

## What is the 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.

## Where we use lap winding and wave winding?

What are the advantages of lap winding?

The advantages of lap windings include: This winding is necessarily required for large current applications because it has more parallel paths. It is suitable for low voltage and high current generators.

### What’s the difference between wave winding and lap winding?

The connection of the wave winding is, the armature coil end is connected to commutator sections at some distance apart. The numbers of the parallel path are equal to the total of number poles. The number of parallel paths is equal to two. The no. of brushes in lap winding is Equivalent to the no. of parallel paths.

### What are the different types of DC winding?

There can be two types of winding in a DC machine, one is called the lap winding and another is called the wave winding. Lap winding is the winding in which successive coils overlap each other. It is named “Lap” winding because it doubles or laps back with its succeeding coils.

What’s the difference between a duplex and lap 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.

## Can you use wave winding in a 4 pole DC machine?

Since average pitch should be a whole number, this winding is not possible with any number of coil sides. For example with 28 conductors in a 4-pole machine, since or being fractional number, the wave winding is not possible but for 26 or 30 conductors, this winding can be employed since or 6 and .
