What is the basic construction of DC motor?
What is the basic construction of DC motor?
A DC motor or machine consists of two windings namely field winding and armature winding. The field winding is stationary and the armature winding can rotate. The field winding produces a magnetic flux in the air gap between the armature and field windings and the armature is placed in this magnetic field.
What are the main parts of DC motor?
DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
What is the rotor part of the DC machine?
A rotor is the rotating part of the DC machine that brings about the mechanical rotations. All these parts put together make up the total construction of a DC motor.
What is armature and field?
The armature is the winding to which the load is connected. In small generators, the field windings are often on the stator, and the armature windings are on the rotor. A synchronous motor is virtually identical to a synchronous generator. Thus, the armature is the stator and the field is the rotor.
What are the parts of DC machines?
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 main parts and function of DC machine?
Basic Components of a DC Machine There are two main parts, the stator and the rotor. The stator contains parts such as brushes, magnets and housing for the whole motor. The rotor contains the windings, the communicator and the output shaft. The two parts work together when voltage is applied to create a moving motor.
What are the main parts of DC machines in construction give the functions of each?
There are two main parts, the stator and the rotor. The stator contains parts such as brushes, magnets and housing for the whole motor. The rotor contains the windings, the communicator and the output shaft. The two parts work together when voltage is applied to create a moving motor.
What are brushes in a DC motor?
In dc motors, the carbon brush makes sure the commutation process remains free from sparks. This contact is a sliding contact capable of transmitting electric current from static to the rotating part of a generator or electric motor. A single or several carbon blocks composes a brush.
What is the outer part of dc machine?
Yoke: The outer frame of a dc machine is called as yoke. It is made up of cast iron or steel. It not only provides mechanical strength to the whole assembly but also carries the magnetic flux produced by the field winding. Poles and pole shoes: Poles are joined to the yoke with the help of bolts or welding.
What are the 3 main parts of a DC generator?
A DC Generator is an electrical device which converts mechanical energy into electrical energy. It mainly consists of three main parts, i.e. magnetic field system, armature and commutator and brush gear.
