What are the parts 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.

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 basic parts elements of a simple DC motor?

The basic parts of an electric motor are DC/AC power supply, stator, rotor, Yoke, Pole shoe, brushes and the slip ring, bearings, shaft, commutator and winding.

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 is the principle of DC motor?

Operating Principle

DC motors operate on Faraday’s principle of electromagnetism which states that a current-carrying conductor experiences a force when placed in a magnetic field.

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.

How a DC motor works step by step?

A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil. One or more windings of insulated wire are wrapped around the core of the motor to concentrate the magnetic field.

What are the advantages of DC motor?

Below are some advantages of DC motors that you should consider:

  • Good speed control. DC motors offer highly controllable speed. …
  • High torque. …
  • Seamless operation. …
  • Free from harmonics.

Why DC current is not used in homes?

DC is mainly not applied for these purposes due to some reasons. For example, heat production due to more power loss compared to AC, more significant dangers of causing a fire, more costs, and problems from converting high voltage and low current to low voltage and high current with the help of transformers.

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 difference between the two main types 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.
