What is the difference between armature and field 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.
What are field windings?
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. It is essential that the field windings of the generator be excited with DC current.
What is an armature winding?
Armature winding can be defined as, an electrical machine in which emf can be generated because of the air gap field flux. It must be noted that the air gap is produced because of the DC current flow in the winding. In general, this winding is housed on slots of the stator & the field winding on rotor slots.
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 difference between armature and rotor?
It is located inside the stator and its objective is to rotate so that in turn the motor shaft or generator rotates. So basically, the rotor consists of a field magnet which rotates while the rotor remains stationary and on the other hand the armature carries current and is stationary and part of the stator.
What is armature winding in DC machine?
DC Armature. The armature of an electric machine is the name historically given to the winding where a voltage is induced and power transfer between electrical and mechanical systems occurs. It is a term used in dc machines and ac synchronous machines. In a dc machine, the armature is the rotating circuit.
What is field and armature?
Usually, the terms “armature” and “field” are applied only to alternating current generators, synchronous motors, DC motors, and DC generators. Thus, the armature is the stator and the field is the rotor. DC machines. In DC machines, both motors and generators, the armature is the rotor, and the field is the stator.
What is the difference between a rotor and an armature?
A rotor is basically – as the word suggests – a rotating electrical component in the mechanism. So basically, the rotor consists of a field magnet which rotates while the rotor remains stationary and on the other hand the armature carries current and is stationary and part of the stator.
What is armature winding what are its different types?
Types of Armature Winding:
| Sr. No. | Types of Armature Winding |
|---|---|
| #1. | Single Phase and Poly Phase Armature Winding |
| #2. | Concentrated Winding and Distributed Winding |
| #3. | Lap, Wave and Concentric or Spiral Winding |
| #4. | Single Layer and Double Layer Winding |
What is armature in electric machine?
In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. The first is to carry current across the field, thus creating shaft torque in a rotating machine or force in a linear machine.
What is the purpose of field winding in DC machine?
Field Winding of DC Motor The field winding basically form an electromagnet, that produces field flux within which the rotor armature of the DC motor rotates, and results in the effective flux cutting.Jum. I 8, 1434 AH
What are the advantages of providing the field winding on rotor and armature winding on the stator?
What are the advantages of providing the field winding on rotor and armature winding on the stator? Explanation: If the armature winding is on the stator, only two slip rings are required which implies less losses, more efficiency and more economy. Also, stationary armature winding can be cooled more efficiently.
What is the difference between rotor and armature?
A rotor is the rotating part in AC motors whilst an armature is the rotating part part in DC motors. A rotor has no commutator bars but an armature has commutator bars which carry currient from the supplier to the windings.
What is Armature Winding Definition: It is a type of winding that is housed in the slots of core and is responsible for the production of flux . The produced flux opposes the developed main field flux known as an armature reaction. Pole Pitch of Armature Winding
What is distributed winding?
distributed winding is one in which the windings are. distributed along a number of slots. the major merit of. this is the heat dissipation is better.
What is a generator field current?
Definition of field current. : the current supplied to the field windings of a generator or motor to establish the magnetic field for its operation.
