In AC electrical machines, to produce a rotating magnetic field, distributed winding is used at stator pheripheri. These windings are of two types, single-layer and double-layer. In a double-layer diamond winding, the slot is divided into an upper and a lower part, and there is one coil side in each half slot. The coil side at the bottom of the slot belongs to the bottom layer of the slot, and the coil side adjacent to the air gap belongs to the upper layer.
A double-layer diamond winding is constructed like the single-layer winding. There are two zone rings, the outer illustrating the bottom layer and the inner the upper layer. The distribution of zones does not have to be identical in the upper and bottom layers. The zone distribution can be shifted by a multiple of the slot pitch. A single zone shift equals a single slot pitch. By comparing the width of the coil with the coil span of the winding, we can see that the coil is now one slot pitch narrower; the coil is said to be short pitched. Because of short pitching, the coil end has become shorter, and the copper consumption is thus reduced. On the other hand, the flux linking the coil decreases somewhat because of short pitching, and therefore the number of coil turns at the same voltage has to be higher than for a full-pitch winding. The short pitching of the coil end is of more significance than the increased number of coil turns, and as a result the consumption of coil material
decreases.
Short pitching also influences the harmonics content of the flux density of the air gap. A correctly short-pitched winding produces a more sinusoidal current linkage distribution than a full-pitch winding. In a salient-pole synchronous generator, where the flux density distribution is basically governed by the shape of pole shoes, a short-pitch winding produces a more sinusoidal pole voltage than a full-pitch winding.
What else can I help you with?
When a transformer winding suffers a short circuit the adjoining turns of the same winding experiences what force?
Both radial and axial forces.
What will happen if two generators are running in parallel but having different winding pitch?
pitch windings are used to suppressed the harmonics. while operating two gen sets in parallel having different pitch windings will certainly cause problems in reducing the harmonics . for example a generator with pitch winding 2/3 suppressed the triple harmonics but may enhance the 5th and 7th harmonics similarly a generator with pitch winding 5/6 suppressed the 5th and 7th harmonics but may enhances the triple ones . so the act would counter act each other.
What types of material can a winding machine be used on?
A winding machine is used to wind the string, wire, cable, thread, rope, etc onto a spool or bobbin. They are of various types from simple winding machines to complex programmable winding machines like CNC winding machines. Mostly winding machines are used in textile, and paper industries, to quickly wrap a large amount of string or paper onto a spool. These winding machines are used by small to large businesses according to the winding needs.
Can a shunt field winding be used as a series field winding in dc series motor?
aster
Winding up for a pitch can properly be called what?
Winding up for a pitch can properly be called the "pitching motion" or "windup." This refers to the sequence of movements a pitcher uses to prepare for delivering the ball, which includes gathering momentum and positioning the body for an effective throw. The windup is crucial for generating speed and control in the pitch.
Is winding a short I or long I?
There are two "i" in the word "winding". The first is long. The second is short.
What meter is used to bench check a motor for short or open winding?
Ohmmeter
Why induction motor is also called short circuit transformer?
Like transformer induction motor has stator winding(Primary winding) and rotor winding(Secondary winding) separated by an airgap.Rotor winding(generally Al bars) are short circuited at the end to produce torque for the rotation.Hence the name short circuited transformer.
What is a Winding-To-Ground Short Circuit?
No
What is a Winding Short Circuit?
When 2 turns of an inductor or transformer short together.
Winding up for a pitch as in baseball can properly be called?
circumduction
What will happen to the transformer if the rated voltage is applied to the winding during short circuit test?
the winding would burn....
Is winding a past or present participle?
Winding can be a present participle when it is used as a verb form (e.g., He is winding the clock). It can also be used as an adjective, such as in "a winding road," which describes the road as having twists and turns.
Is winding up for the pitch kinetic or potenchal energy?
Winding up for a pitch involves storing potential energy in the pitcher's muscles and body position. As the pitcher releases the ball, the potential energy is converted into kinetic energy, resulting in the fast motion of the pitch.
When a transformer winding suffers a short circuit the adjoining turns of the same winding experiences what force?
Both radial and axial forces.
Why you do insulation resistance test?
in order to avoid unwanted short circuit break downs.... short circuit can burn the transformer and motor winding.... Megger is the device used to check the insulation .
