In any electric motor, operation is based on simple electromagnetism.
A current-carrying conductor generates a magnetic field; when this is then placed in an external magnetic field, it will experience a force proportional to the current in the conductor, and to the strength of the external magnetic field.
Dc motor basic parts
Every DC motor has six basic parts-axle, rotor , stator, commutator, field magnet(s), and brushes.
In most common DC motors , the external magnetic field is produced by high-strength permanent magnets ,
Stator-stationary part of the motor
rotor -consists of windings
Detailing of Parts
The two important parts of a Dc motor is the Rotor & Stator.
In simple words Rotor is the rotating part of motor & Stator is the stationary part of the motor.
The Rotor actually as two sides in middle there is a AXLE, means that it is like a wheel which helps the Rotor to rotate.
The Rotor is covered with the windings.
These parts are actually placed in another part that’s called the Metal FRAME.
The most basic part needed for working of any kind of motor is the FIELD MAGNETS.
Basic words related to a DC Motor
TORQUE- Any kind of Force on the system(conductor).
STARTER -Device that creates a Force internally that tends due an internal combination to cause Rotation of the engine(motor.)
LOAD- External force acting on the mechanism.

Types of Motors
There are various types of motors having the same basic principle:
1. Synchronous Motors
2. Induction Motors
4. Universal motors

The following are the important points that should be noted while considering a DC MOTOR:
