What is the construction of DC motor?
What is the 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 is the principle of operation of dc machine?
The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.
What is DC motor with diagram?
Difference Between Dynamo and DC Motor – definition
| Sr No. | Dynamo | DC Motor |
|---|---|---|
| 2. | Here normally permanent magnet is used or electromagnets made up of windings | Made of miniature size of permanent magnet |
| 3. | It can operate through Self Excitation or Separate Excitation | It is usually excited by permanent magnet present. |
What are the main parts of DC motor?
What are DC Motor Parts and how they work?
- Stator. A stator is one of the DC motor parts that is, as the name suggests, a static unit containing the field windings.
- Rotor.
- Yoke.
- Poles.
- Field Windings.
- Armature Windings.
- DC Motor Commutator.
- Brushes.
What is the main function of a DC motor?
A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through direct current, and convert this energy into mechanical rotation.
What are the two main parts of a 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 symbol of DC motor?
IEC Symbol Preview – DC Motors
| Horizontal Symbol | Vertical Symbol | Description |
|---|---|---|
| HMO1M15 | VMO1M15 | DC Motor – Stepping with Permanent Magnets |
| HMO1M7 | VMO1M7 | DC Motor – Series Excitation |
| HMO1M8 | VMO1M8 | DC Motor – Derived Excitation |
| HMO1M12 | VMO1M12 | DC Motor – Independent Excitation |
What are the main 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 applications of DC machine?
Generally, the DC machines are used in supplying excitation of an alternator and it is also used in many applications like welding process, variable-speed motor drives and electrolytic and electroplating process. Small DC machines are used as a control device such as speed sensing, positioning, and tracking.
What is DC motor example?
1 Introduction. Direct-current motors are extensively used in variable-speed drives and position-control systems where good dynamic response and steady-state performance are required. Examples are in robotic drives, printers, machine tools, process rolling mills, paper and textile industries, and many others.
What are the parts of DC motor?
What makes up the construction of a DC motor?
All these parts put together make up the total construction of a DC motor. If you would prefer a video explanation, here is a video on the construction of DC machines: The magnetic frame or the yoke of DC motor made up of cast iron or steel and forms an integral part of the stator or the static part of the motor.
Can a DC generator be used as a motor?
Both the DC machines i.e. DC generator and DC motor have the same construction. Therefore, either machine can be used as a motor or a generator. So the following discussion about the construction of DC motor is equally valid for the construction of the DC generator. Also, we can entitle it as the construction of DC machine.
What kind of magnetic field does a DC motor have?
The field winding is stationary and 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. The construction of DC motor or machine is shown in Figure.
Which is the static part of a DC motor?
A stator is the static part of the DC machine that houses the field windings and receives the supply. A rotor is the rotating part of the DC machine that brings about the mechanical rotations.
