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 is the function of armature winding of a motor?
Armature is a rotating part of the machine, the coil which wound in the core of that rotating part.
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 happens if load of DC series motor is disconnected?
In D.C Shunt motor, the field winding is connected parallel with the armature winding.. If you remove the supply to armature winding, the motor will stop after some time.
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.
What is coil pitch?
The distance between the two sides of an individual coil of and AC armature winding id termed the coil pitch.
What is an armature made of?
The armature is the part of an electric generator or motor that contains the main current-carrying winding. It usually consists of a coil of copper wire that is wound around an iron or steel core. The coil and core are placed in a magnetic field, which is produced by one or more permanent magnets or electromagnets.
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 is the function of armature winding of a motor?
Armature is a rotating part of the machine, the coil which wound in the core of that rotating part.
What is the difference between armature reaction and armature reactance?
Armature reaction refers to the magnetic field distortion caused by the armature current in a machine, affecting its performance. Armature reactance, on the other hand, is a component of the total impedance in an electrical circuit due to the inductive nature of the armature winding, influencing the current flow. In essence, armature reaction deals with the magnetic field, while armature reactance deals with the electrical characteristics of the armature winding.
What are the parts of simple loop generator?
yoke,magnetic poles,armature,field winding,shaft,armature winding,commutator
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.
What is the purpose of a coil winding machine?
For winding coil.
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 happens if load of DC series motor is disconnected?
In D.C Shunt motor, the field winding is connected parallel with the armature winding.. If you remove the supply to armature winding, the motor will stop after some time.
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 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 .
