What is Brushless DC Motor?
Brushless Electric Motor(BLDC Motor) is a type of motor that don't have brush, meaning there are no brush or commutator between its rotor and stator. The direction of current in the windings of a brushless motor is controlled by a controller, which provides direct current in various directions. It employs electronic commutation using built-in sensors and an electronic commutator primarily to eliminate brush wear and the noise generated by brush contact. Brushless electric motors are highly efficient DC motors.

What is Brushed DC Motor?
The working principle of a Brushed motor is quite simple, consisting of two main components: the stator and the rotor. The stator contains several coils that are supplied with current from a DC power source, creating a magnetic field. The rotor, on the other hand, consists of a set of magnetic poles. When the magnetic field interacts with the magnetic poles, electromagnetic forces are generated, causing the rotor to rotate. Additionally, the rotor is equipped with a set of brushes that make contact with electrodes on the stator. By switching the direction of the current through the brushes, the motor can achieve forward and reverse rotation.
Brushed DC Motor Advantages
Due to its simple structure, low manufacturing cost, and advantages such as easy control and high power density, brushed motors are widely used in various fields including household appliances, machinery, and automotive applications. They offer reliable performance and are capable of meeting the power requirements of various devices and systems.
