Today we are going to discuss the problem is the heat dissipation fan in the brushless motor andbrush motorwhich noise is less.

Brushless motors are less noisy thanbrushless motors. Brushless motors operate by controlling electromagnetic fields electronically, eliminating the need to use traditional brushes and commutators, thereby reducing mechanical friction and vibration, and thus reducing the possibility of noise generation. Therefore, forcooling fans, brushless motors have the advantage of less noise than brushless motors.

During the operation of the brush motor, due to the friction between the carbon brush and the commutator, it will produce a large noise. This noise not only affects the user experience, but can be a problem in some environments where quiet is required.
