Why armature winding resistance is less than field winding resistance?
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.
Does a starting winding has more or less turns than a running winding?
Starting winding has more resistance and less induction than main winding, this means has smaller diameter and less turns.
What is the difference between turn coil and winding of a transformer?
coil is equals to no. of turns.AnswerIn electrical engineering, a transformer's 'winding' is the name given to what the layman would generally call a 'coil'. However, it is a little more complicated than that, as a transformer's 'winding' often consists of several 'coils' connected in series.Windings are made up of 'turns' -i.e. one complete circumference of a winding taken by a conductor.
Which winding has the higher resistance start or run in single phase motors?
start winding is thicker with less number of winding whereas run winding is less thicker than start winding but with more number of winding. As we know inductance depends upon numbers of turns of winding so run winding will have more inductance.
Why short pitch winding is used?
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 materialdecreases.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.
How do you test fire an ignition coil?
You test an ignition coil by checking the resistance with an ohm meter. The resistance values should be something like, Primary winding .3 to 1 ohms, Secondary winding 8,000 to 11,500 ohms.
Does series field winding have more resistance or a shunt field winding?

Where can someone find information about coil winding recycling?
Information about coil winding recycling can be found out from your local recycling plant. You can also look on Scrap Metal Junkie to find out where coil winding can be recycled.
What are the release dates for Coil Winding Machines - 1904?
Coil Winding Machines - 1904 was released on: USA: May 1904
Is a coil a simple machine screw?
No because a screw is has a top and a winding bottom and a coil does not have a top and has a winding bottom so no a coil is not a simple machine screw.
One induction motor winding is burned and still showing equal winding resistance and low insulation resistance value?
you probably have a winding to winding short. you need an a pluse tester or an ac ohmmeter each coil is slipped into a slot lined with fish paper (cambric) each wire in the coil is insulated with a thin layer of varnish with formed coils rather them mush coils it can be a one turn short mush coils give several turns it acts like a transformer with a short in the secondary
Which winding has the higher resistance start or run in single phase motors?
start winding is thicker with less number of winding whereas run winding is less thicker than start winding but with more number of winding. As we know inductance depends upon numbers of turns of winding so run winding will have more inductance.
