What are the different parts of DC machine?
Parts of a DC Generator
- Stator. The main function of the stator is to provide magnetic fields where the coil spins.
- Rotor. A rotor in a DC machine includes slotted iron laminations with slots that are stacked to shape a cylindrical armature core.
- Armature Windings.
- Yoke.
- Poles.
- Pole Shoe.
- Commutator.
- Brushes.
What are the 4 main parts of a DC motor?
These components are: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes. Many of its parts are the same as parts of AC motor, but with a little change.
What are the three main parts of a DC motor?
It mainly consists of three main parts, i.e. Magnetic field system, Armature and Commutator and Brush gear. The other parts of a DC Generator are Magnetic frame and Yoke, Pole Core and Pole Shoes, Field or Exciting coils, Armature Core and Windings, Brushes, End housings, Bearings and Shafts.
What are the main parts of DC machines in construction?
It mainly consists of three main parts, i.e. magnetic field system, armature and commutator and brush gear. The other parts of a DC Generator are magnetic frame and yoke, pole core and pole shoes, field or exciting coils, armature core and windings, brushes, end housings, bearings and shafts.
What are the various parts of electrical machine?
It commonly consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field.
Which part of DC machine has windings?
armature
In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current.
How many parts does a DC motor have?
Every DC motor has six basic parts — axle, rotor (a.k.a., armature), stator, commutator, field magnet(s), and brushes.
What are the parts of DC motor starter?
The name comes from the number of terminals that connect to the motor, with 3 point starters having three terminals: the armature terminal, which is connected to the motor armature winding; the line terminal, which is connected to the positive supply pole; and the field terminal, which is connected to the field winding …
What are the different parts of a DC generator explain the function of each part?
Stator is the stationary part of this system that includes a core, stator winding, and the outer frame and houses the rotor (the rotating part) in its core. Among parts of dc generators, the stator is a key component and its main function is to supply magnetic fields around which the coils spin.
How does DC motor differ from DC generator in construction?
The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts mechanical energy into an electrical energy.
Which part of a DC machine is laminated Why?
Eddy current losses are directly proportional to area of armature or more precisely the path of motion. In laminated armature eddy current losses are reduced to very less or ‘0’ quantity. That is why armature of DC machines (either motor or generator) is laminated.
What is DC machine in electrical?
A DC Machine is an electro-mechanical energy conversion device. There are two types of DC machines; one is the DC generator, and another one is known as DC motor. A DC generator converts mechanical power (ωT) into DC electrical power (EI), whereas, a DC motor converts d.c electrical power into mechanical power.
What are the basic parts of a DC shunt motor?
This motor can be constructed with the basic parts like field windings (stator), a commutator and an armature (rotor). The working principle of a DC Shunt Motor is, whenever a DC motor is turned ON, then DC flows throughout stator as well as the rotor.
Why shunt wound DC motor is called a constant flux motor?
But we know that the armature current is proportional to the field flux (Ish ∝ Φ). Thus the Φ remains more otherwise less stable, due to this reason; a shunt wound DC motor can be named as a constant flux motor. Whenever the DC shunt motor’s armature winding rotates within the magnetic field which is generated by the field winding.
How does a shunt field work?
The shunt field can be separately excited from the armature windings and that is the reason it can be used for greater speed regulation and can also offer very simplified reverse control. Here, a large wire carrying the full armature current winds the field with few turns.
What are the essential parts of a DC machine?
The construction of the DC machine can be done using some of the essential parts like Yoke, Pole core & pole shoes, Pole coil & field coil, Armature core, Armature winding otherwise conductor, commutator, brushes & bearings. Some of the parts of the DC machine is discussed below. Another name of a yoke is the frame.
