The field winding on a generator is the winding that is electrified to create an electromagnet; it is generally the winding found on the rotor (the rotating part of the generator).

What is the difference between a field winding and an armature winding in any machine?
simply saying u that field winding is a winding present at the stator of the motor and is used to produce the magnetic field and the armature winding is the winding present in the rotor and is used to rotate the shaft of the motor. there are some machines with permanent magnets, those permanent magnets are used as the major source of magnetic flux in the machine instead of the field winding .
What would the power loss be if the series field winding of dc motor connected directly across the 240 V dc supply?
Detailed Solution. For a constant back emf, flux is inversely proportional to the speed of the motor. If field winding is disconnected accidentally, the speed would dangerously increase in order to maintain the back emf of the motor
What is the function of field winding in DC generator?
The motor needs the current and magnetic flux to create motion The magnetic field is created by field winding where as armature carries the current resulting into the rotation of armature
What type of current flows in stator and rotor winding of a dc shunt generator?
The field winding in the stator is exposed to the full current generated by the rotor's winding.
Why is the shunt field resistance greater than the series field resistance?
In case of series winding total line current is flow through it.line current is very very high.so,to minimize the drop the winding made as low turns and low gauge.hence the resistance is low.in case of shunt winding high resistance winding is used otherwise short circuit the parallel winding.for that winding is made as heavy turns and heavy gauge.
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 series field winding have more resistance or a shunt field winding?
shunt field winding have more resistance than series field winding ************sai ganesh ************269*******
Can a shunt field winding be used as a series field winding in dc series motor?

What happens if field winding of a running dc shunt motor suddenly breaks open?
when the field winding of a running dc shunt motor suddenly breaks open the motor fails to run because in the motor the stationary winding is armature and rotatory is field winding
How winding creates a magnetic field?
Current flow in any conductor creates a magnetic field, winding just concentrates it.
What is the difference between a field winding and an armature winding in any machine?

Answering Which one is a separately excited generator - ac generator or dc generator?
Excitation is the phenomenon by which you control the excitation of field winding of a generator. In DC generator field winding is placed on stator and this field winding can be self excited or seperately excited depending upon the type on generator used. AC generators can also be self excited or seperately excited type but field winding is placed on rotor nad armature winding on stator.
What would the power loss be if the series field winding of dc motor connected directly across the 240 V dc supply?
Detailed Solution. For a constant back emf, flux is inversely proportional to the speed of the motor. If field winding is disconnected accidentally, the speed would dangerously increase in order to maintain the back emf of the motor
Why there is power dissipation in field winding whereas it is negligible in armature winding?
There are losses associated with both, but I don't think that's what you're getting at. The power applied to the field winding, typically on the rotor of a generator, is used to turn the field winding into an electromagnet; This electromagnet is forced to spin, which induces a current in the armature windings. This induced current is the power output from the generator. So a little power is lost/used in the field winding to convert the kinetic energy from the turbine into electric energy.
What is the function of field winding in DC generator?
The motor needs the current and magnetic flux to create motion The magnetic field is created by field winding where as armature carries the current resulting into the rotation of armature

What are field windings and armature windings in a dc motor and generator?
generators have two types of winding , * at armature also called armature winding( winding around shaft , we can say), which is the moving part. note that armature also consists of magnets along with windings. hence produces field arount it. * and at stator also called field winding, because when armature rotates its flux(field) is cutted by the stator windings and produces mutually induced e.m.f in it( in stator windings off course) causing current to flow. this current also produces some electric field around it which is in return cutted by the armature windings hince a little amount of e.m.f ( also called back e.m.f) produced in armature due to stator winding current. know this current in armature (due to back e.m.f produced by stator winding) produces additional field , hence causing more current in stator winding. this is the reason that why stator windings are called field winding( as they cause electric field of armature stronger and cause more current in output). note that out put is taken from the stator windings in generators.
