What are the functions of field winding?

Field winding is used in alternators and synchronous motors. The purpose of the field winding is to create a rotating magnetic field inside the equipment. In alternator the rotation will be initiated from outside and for the synchronous motor it will be from inside.

What is the purpose of field winding in starter motor?

The purpose of starter field coils is to conduct an electric current that causes a magnetic flux around the starter armature. The armature also has a magnetic field around it, and the interaction between the two forces causes the movable armature to turn.

How do armatures work?

In electrical engineering, an armature is the component of an electric motor which carries alternating Current. When the machine or motor is used as a motor, this EMF opposes the armature Current, and the armature converts electrical power to mechanical power in the form of Torque and transfers it via the shaft.

What is the function of armature winding and field winding?

The armature winding is the winding where the voltage can be induced. Similarly, the field winding is the winding where the main field flux can be generated whenever the current flows through the winding.

What is the role of field winding Mcq?

Explanation: The field winding should be designed for a voltage from 15-20\% less than the exciter voltage. This is because to allow for the drop in voltage between field and exciter and to allow for variations in the reluctance of the magnetic field.

What is field winding and stator winding?

In most modern installations, a synchronous generator is used as the exciter. For this purpose, the field windings of the exciter are placed on its stator and the phase windings on its rotor. A rectifier mounted on the rotating shaft is used to convert the alternating current to direct current.

What is field winding in generator?

field winding in Electrical Engineering A field winding is the insulated current-carrying coils on a field magnet that produce the magnetic field needed to excite a generator or motor. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding.

What is difference between field winding and armature winding?

Armature Winding is the winding, in which voltage is induced. Field Winding is the winding in which the main field flux is produced when the current through the winding is passed.
