6. DC Motor or Direct Current Motor.
What is DC Motor..?
 This is a device that converts DC
electrical energy to a mechanical
energy.

7. Types of DC Motor:

8. Construction of DC Motor
Stator: The static part that houses the field windings and
receives the supply and,
Rotor: The rotating part that brings about the mechanical
rotations.

9. Other than that there are several subsidiary parts
namely the

 2.Poles of DC motor
 3.Field winding of DC motor
 4.Armature winding of DC motor
 5.Commutator of DC motor
 6.Brushes of DC motor

11. TORQUE
The vector multiplication of position vector and
force on that point is called Torque.

12. SPEED
The rotational speed or angular velocity, is typically
measured in radians/second {rad/s}, revolutions/second
{rps}, or revolutions/minute {rpm}.

13. Power
 When you pedal a bicycle, you apply forces to a rotating
body and do work on it. Similar things happen in real-life
situations, such as a rotating motor shaft driving a power
tool or a car engine propelling the vehicle. We can
express this work in terms of torque and an angular
displacement...
 Power in rotational motion can be written as:
