it must be brushless! Brushed motors are prone to heat due to high friction, and carbon brushes often need to be replaced, resulting in low work efficiency and high replacement cost; Brushless motor runs without mechanical wear and corrosion, and there is no spark when it is turned on and off. Compared with traditional brush motor, the service life of the whole machine is improved by 3 times. Wexers brushless motor WU278 is a brushless motor, which does not need to replace the carbon brush. At the same time, it also has patented reverse self-stop technology, which is very durable!
