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
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.
Why are the compensating winding used in dc motor?
compensating winding is used for equal load sharing of two generators running in parallel. while interpole winding is used to minimise the effect of armature reaction by supporting the main field.
What is the function of winding in motor?
because its winding follows the wave sign
What is the function of armature winding?
The winding function of an electric motor is a description of how the number of conductors in the windings around the motor changes with position.
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 dc motor has its field winding in parallel with its armature windings?
Shunt Motor
What is DC shunt motor?
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
What is shunt current and a armature current?
The terms 'shunt' and 'armature' apply to a particular type of d.c. motor, in which the field windings are connected in parallel with the armature windings. 'Shunt' is an archaic term for 'parallel', so the term 'shunt', in this context, means that the field winding is connected in parallel with the armature winding. The terms 'shunt current' and 'armature current', then describe the currents flowing in the shunt winding and armature winding, respectively.
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 armature winding is star connected for synchronous motor?
Because your momma said so

What is the purpose of the fields of a dc shunt motor?
DC Shunt motor: dc shunt motor is a motor with dc supply given to the inductor connected in parallel with the armature of a motor. The inductor connected in parallel with the armature of a motor called field winding of a motor.In dc shunt motor: When current flows through a conductor ( here it is armature in case of dc shunt motor ), magnetic field is produced which is circular and when this conductor is placed perpendicular in the magnetic field ( which is produced by the current or say dc supply that given to the inductor or say field winding of the dc shunt motor ), the main magnetic lines get bent due to the interaction of the two fields. These lines of force experience tension and try to become straight. So, a force is produced on the conductor ( armature ), due to which the conductor ( armature ) will rotates. The direction of force can be found by Fleming's right hand rule.Main Answer: Thus, it should be understood that field winding in dc shunt motor stands to get interaction of the two field in such a way that force is produced on the armature so that the armature get to rotate.Some Facts: Actually the current in armature is due to the mutual induction by field winding to the armature. That means only field winding get dc supply through which current and so magnetic field is produced in armature that try to oppose due which it is produced, that means it oppose the main magnetic field of field winding.
What is armature amps?
Armature amps refer to the current flowing through the armature winding of an electric motor or generator. It is used to power the electromagnetic coils that generate the magnetic field needed for the motor or generator to operate efficiently. Monitoring armature amps is crucial for maintaining the proper functioning and performance of the motor or generator.
