A brushed DC electric motor, also known as a brushed motor, is a type of electric motor that uses direct current (DC) to generate mechanical energy This type of motor is widely used in various applications due to its simplicity, efficiency, and versatility In this article, we will explore the inner workings of a brushed DC electric motor and delve into its benefits and applications.
### How Brushed DC Electric Motor Works
At the heart of a brushed DC electric motor is a rotating armature or rotor surrounded by a stationary magnetic field created by a set of coils known as the stator The rotor is connected to a commutator, which is a split ring made of copper segments Carbon brushes are used to transfer electrical current from the power source to the commutator segments, ensuring a continuous flow of electricity to the rotor.
When an electrical current is supplied to the motor, the rotor becomes magnetized due to the interaction with the magnetic field created by the stator This generates a torque that causes the rotor to rotate, thus producing mechanical motion As the rotor spins, the brushes make contact with different segments of the commutator, reversing the direction of the current flow to ensure a continuous rotation of the rotor.
