Which is not part of a DC motor?
The correct answer to the question will be compass i.e compass is not a part of a DC motor. Various parts of a DC motor are coil of wire, armature, field magnets, brushes and commutator. … The brushes connected to the coil provides the current through a split ring called commutator.
What is the name of the part of 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.
Which of the following is not a part of DC generator?
Sliprings is not a part of direct current generator.
What are the 4 types of DC motor?
There are 4 main types of DC motors:
- Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux. …
- Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. …
- Shunt DC Motors. …
- Compound DC Motors.
What is in a DC motor?
A DC motor consists of an stator, an armature, a rotor and a commutator with brushes. Opposite polarity between the two magnetic fields inside the motor cause it to turn. DC motors are the simplest type of motor and are used in household appliances, such as electric razors, and in electric windows in cars.
What is DC motor with diagram?
Difference Between Dynamo and DC Motor – definitionSr No.DynamoDC Motor2.Here normally permanent magnet is used or electromagnets made up of windingsMade of miniature size of permanent magnet3.It can operate through Self Excitation or Separate ExcitationIt is usually excited by permanent magnet present.1а
What are the applications of DC motor?
Applications. DC motors are suitable for many applications – including conveyors, turntables and others for which adjustable speed and constant or low-speed torque are required. They also work well in dynamic braking and reversing applications, which are common in many industrial machines.
Where is DC motor used?
Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives for steel rolling mills.
What does DC stand for?
District of Columbia

What are the parts of a DC generator?
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 is the name of DC generator?
There are three methods of excitation, and thus three main types of DC generators: Permanent Magnet DC Generators – Field coils excited by permanent magnets. Separately Excited DC Generators – Field coils excited by some external source. Self Excited DC Generators – Field coils excited by the generator itself.
What is the most common type of dc motor?
Mainly there are two types of DC Motors. One is Separately Excited DC Motor and other is Self-excited DC Motor. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor.
Which DC motor is best?
Series wound DC motors are best for applications that require high startup torque, without the need for speed regulation. Like a shunt motor, as a load is applied to a DC series motor, the motor speed decreases, which reduces the back EMF and increases the net voltage.
