How a Brushed DC Motor Works?

A brushed DC motor is a type of electric motor that uses direct current (DC) electricity to produce rotational motion. The motor consists of several key components, including a stator, rotor, and commutator, which work together to convert electrical energy into mechanical energy.

How a Brushed DC Motor Works

1. The stator is the stationary part of the motor and consists of a magnetic field coil, or field winding, which creates a magnetic field.

2. The rotor is the rotating part of the motor and contains an armature winding, which is a coil of wire that carries the electric current.

3. When a DC current is applied to the armature winding, it produces a magnetic field that interacts with the magnetic field of the stator. This interaction causes the rotor to rotate.

4. The commutator is a switching mechanism that reverses the current flowing through the armature winding at regular intervals, which allows the rotor to continue rotating in the same direction.

5. As the rotor rotates, it turns the shaft of the motor, which can be used to drive mechanical loads such as fans, pumps, and conveyor belts.

Conclusion

Overall, the basic operation of a brushed DC motor is similar to that of an AC motor, but the use of direct current allows for more precise control of the motor's speed and direction. Additionally, the use of a commutator and brushes allows for the reversal of current in the armature winding, which is necessary for the continuous rotation of the rotor.
