Characteristics of brushless motors

Brushless motors have higher efficiency compared to traditional brushed motors. Due to the fact that brushless motors do not require brushes and brushes to achieve rotor commutation, energy loss is reduced and motor efficiency is improved.
Brushless motors can operate at higher speeds due to the lack of friction between brushes and electric brushes. This gives motors an advantage in applications that require high-speed operation, such as drones, power tools, etc.

Compared to brushed motors, it has a higher power density. Due to the simpler structure of the motor, without brushes and brushes, it can be designed more compactly and provide higher power output.
The lifespan of brushless motors is usually longer than that of brushed motors. The motor has no brush or brush wear, reducing the need for maintenance and replacement, and extending the service life of the motor.
Overall, brushless motors have the characteristics of high speed, long lifespan, and low noise, which make them widely used in many fields.
