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.

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.

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
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 winding is connected to the source?
In a transformer, the winding connected to the source is called the primary winding. This winding receives the input voltage and current from the power supply. The primary winding creates a magnetic field that induces a voltage in the secondary winding, allowing electrical energy to be transferred between the two.
Why armature winding resistance is less than field winding resistance?

What is function of a stator in alternator?
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.
What is field winding?
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).
Can a shunt field winding be used as a series field winding in dc series motor?

What is The stationary winding assembly in an alternator called?
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.
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?
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.
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
