What is the difference between lap winding and wave winding?
The lap winding can be defined as a coil which can be lap back toward the succeeding coil. The wave winding can be defined as the loop of the winding can form the signal shape. The connection of the lap winding is, the armature coil end is connected to the nearby section on the commutators.
What is lap winding in dc machine?
Lap windings is a very simple and normally used winding in dc machines rotors. Simplex lap windings have two ends points and more than one number of turns and its endpoints are connected with neighboring commutators segments.
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 two types of winding in dc machine?
Types of Armature Winding of a DC Machine – Lap Winding and Wave Winding.
What are types of DC machine explain lap and wave winding?

What are types of dc machine explain lap and wave winding?
How many types of windings are there in a dc machine?
In machine winding we have two main types of windings these are (a) lap winding. (b) Wave winding as shown in figure (3-1). In each type three are two modes (Progressive and Retrogressive).
How many types of windings are in a DC motor?
three type’s
These windings are categorized into three type’s namely simplex, duplex and triplex type winding.
What is difference between concentrated and distributed winding?
The major difference between the concentrated and distributed winding is that, concentric oils are used in concentrated winding whereas coils are spread along the air gap periphery in distributed winding.
What are different types of windings?
Types of Motor Windings:
- #1. Stator Winding:
- #2. Rotor Winding:
- #3. Lap Winding:
- #4. Wave Winding:
The armature winding is mainly classified into two types, i.e., the lap winding and the wave winding. One of the major difference between them is that in a lap winding the end of each coil are connected to the adjacent segment whereas in the wave winding the end of armature coil connected to commutator segment at a distance apart.
What type of armature winding is used in DC machines?
In DC machines, the drum type armature windings are used. In the case of drum type winding, the armature conductors (in the form of coils) are placed in the slots around the surface of cylindrical or drum shaped armature core.
Why are wave windings used in small machines?
The wave windings are used in small machines, since in the case of small machines the current carrying capacity of armature conductors is not critical.
What is the commutator pitch for lap winding and wave winding?
If lap coils are traversed (refer figure for lap winding), the movement is forward and backward alternatively. If wave coils are traversed (refer figure for wave winding), the movement is forward only. The commutator pitch for lap winding is always 1.
