Working Principle of a DC Motor
When an electric current flows through the armature, it creates a magnetic field. The magnetic field interacts with the field magnets, causing a torque that rotates the rotor. The commutator and brushes ensure the continuous flow of current in the armature, which maintains the rotation.	Image Source

Types of DC Motors
There are several types of DC motors, including brushed motors, brushless motors, and stepper motors. Brushed motors use brushes and commutators to control the flow of current. Brushless motors use electronic controllers to control the current flow, eliminating the need for brushes.	Image Source

DC Motor Speed Control
The speed of a DC motor can be controlled by varying the input voltage or by adjusting the field current. Increasing the voltage increases the speed, while reducing the voltage decreases the speed. By changing the field current, the magnetic field strength can be adjusted, affecting the motor's speed.	Image Source
