Which of the following is not a part of DC motor?

Damper winding is not a part of DC Machines while all other are the parts of dc machines.

What is the name of the part 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.

Which of the following is not a part of DC generator?

Sliprings is not a part of direct current generator.

Which is not part of a DC motor a coil of wire B magnet C compass D brush e commutator?

In a DC motor, commutator is used to reverse the direction of the armature current in the brush zone so that the torque is exerted in same direction. Therefore, The compass is not a part of a DC motor.

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 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 is the emf equation of generator?

As the armature rotates, a voltage is generated in its coils. In the case of a generator, the emf of rotation is called the Generated emf or Armature emf and is denoted as Er = Eg. In the case of a motor, the emf of rotation is known as Back emf or Counter emf and represented as Er = Eb.

What is the use of brushes in DC motor?

A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator, and, as regards DC machines, ensuring a spark-free commutation.

What are the materials used for brushes in DC machine?

Metal Graphite Brushes are generally made from natural graphite and finely divided metal powders. Copper is the most common metallic constituent but silver, tin, lead and other metals are sometimes used. These brushes are often ideal for a wide variety of applications because of their low resistivity.
