A field winding is the insulated current-carrying coils on a field magnet that produce the magnetic field needed to excite a generator or motor. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding.

Whats the definition of winding?
Definition of winding (Entry 1 of 2) 1 : material (such as wire) wound or coiled about an object (such as an armature) also : a single turn of the wound material. 2a : the act of one that winds. b : the manner of winding something. 3 : a curved or sinuous course, line, or progress.
What is the meaning of winding road?
Drivers encountering a winding road sign must be prepared to slow down as the sign designates a section of curved road ahead. Winding road signs are used in situations where there are three or more curves in the road where each curve is separated by a tangent distance of less than 600 feet.
What is the difference between wind and wind?
What is an example of winding?
A path through the woods that has plenty of bends and curves in it is winding, and a river that curls and meanders down to the sea is also winding. The Beatles song “The Long and Winding Road” describes a twisting, indirect road.
What causes winding?
Winding occurs due to a temporary paralysis (spasm) of the diaphragm muscle. It is often caused by a direct blow to the abdomen and/or chest, a fall on the back, or a fall on the buttocks. Although it can be briefly traumatic, often leading the athlete to panic or hysteria, the condition is of no real significance.
What are the types of winding?
These windings are categorized into three type’s namely simplex, duplex and triplex type winding.
What is difference between coil and winding?
Coil: A coil is formed by connecting several turns in the series. Winding: A winding is formed by connecting several coils in series.
Why field winding is DC?
The field winding in shunt DC motors is made of many windings of thin wire, to both increase the magnetic field’s strength and limit the current through the coil. The current is reduced through the field coil and thus increases in the armature.
What type of word is winding?
Winding can be a verb, a noun or an adjective.
What is the sentence of winding?
2. A winding lane led down towards the river. 3. In the beautiful park, there is a path winding along the lake.
What is the meaning of long and winding?
1 : tediously long in speaking or writing. 2 : not easily subject to loss of breath. Other Words from long-winded Synonyms & Antonyms Learn More About long-winded.
What are the 4 types of wind?
Types of Wind – Planetary, Trade, Westerlies, Periodic & Local Winds.
What are two definitions of wind?
Definition of wind (Entry 1 of 5) 1a : a natural movement of air of any velocity especially : the earth’s air or the gas surrounding a planet in natural motion horizontally. b : an artificially produced movement of air.
What are the three types of winds?
There are three main types of planetary winds – the trade winds, the westerlies and the easterlies. These winds are named according to the direction from which they blow.
What are the objectives of winding?
Objectives of Winding: Firstly, to transfer yarn from spinning bobbin package to a convenient yarn package. Secondly, to improve the quality of yarn. Thirdly, it facilites to get suitable yarn package. After that, to get a quality fabric.
What is electric motor winding?
The motor winding refers to the type of winding of the electrical conductor for generating a magnetic field used to drive the rotors in an electric motor – e.g. a servo motor. The design determines the available torque, the electromagnetic force in the system, the electrical resistance, and therefore the application.
What is armature winding?
Armature winding can be defined as, an electrical machine in which emf can be generated because of the air gap field flux. It must be noted that the air gap is produced because of the DC current flow in the winding. In general, this winding is housed on slots of the stator & the field winding on rotor slots.
What is a 3-phase motor?
Three-phase motors are a type of AC motor that is a specific example of a polyphase motor. These motors can be either an induction motor (also called an asynchronous motor) or a synchronous motor. The motors consist of three main components – the stator, the rotor, and the enclosure.
Why do motor windings burn?
The complete insulation burn out on all phases is normally caused by high currents in the stator winding due to locked rotor. This can also occur due to excessive starts and reversions.
What is a stator winding?
Stator Windings. The stator core holds 3-phase windings which get supply from a 3-phase supply system. Stator windings include six terminals where two of every phase is connected to the terminal box in the machine.
What are the types of armature?
- Single phase and poly phase armature winding.
- Concentrated winding and distributed winding.
- Half coiled and whole coiled winding.
- Single layer and double layer winding.
- Lap, wave and concentric or spiral winding and.
- Full pitched coil winding and fractional pitched coil winding.
Which winding is used in transformer?
Helical Windings or Spiral Windings Helical windings are known as spiral windings which are used for low voltage & high capacity-based transformers, where the flow of current is higher & the turns of winding are smaller. The transformer output changes from 160 to 1000 kilovolt-ampere & 0.23 to 15 Kilovolt.
Where is wave winding used?
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.
What is armature and field?
The field of a synchronous generator is the winding to which the DC excitation current is applied. The armature is the winding to which the load is connected. In small generators, the field windings are often on the stator, and the armature windings are on the rotor.
