The field winding assembly is a component of electric machines, such as motors and generators, that generates a magnetic field when electrical current flows through it. It typically consists of coils of wire wound around a core, often made of iron. In motors, this assembly can be found in the stator, while in generators, it may be located on either the rotor or stator, depending on the design. The assembly is crucial for the machine's operation, as it influences the strength and direction of the magnetic field.
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.

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
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.
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.

The stator is the stationary winding assembly that makes the magnetic field inside the alternator. It is this magnetic field that the armature rotates in generating the electricity.
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).

The stationary winding assembly in an alternator is called the stator. It consists of multiple coils of wire wound around a core, which generates alternating current (AC) when the rotor, a rotating magnetic field, passes by it. The stator is essential for the conversion of mechanical energy into electrical energy in the alternator.

Current flow in any conductor creates a magnetic field, winding just concentrates it.
In electrical machines such as motors and generators, the field winding is responsible for producing a magnetic field within the machine. This magnetic field interacts with the armature winding, which carries the electric current and generates mechanical power. The field winding typically has fewer turns of thicker wire compared to the armature winding, which has more turns of thinner wire to handle higher currents.
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.
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
