Does electric wrench come with carbon brush or without carbon brush?
Brushless motor operation without mechanical wear, no electrical corrosion, switch machine instantaneous no spark, compared to the traditional brush motor, the whole machine life expectancy increased 3 times.
It must be good without brush!Brush motor friction, easy to heat, often need to replace carbon brush, resulting in low efficiency, high cost of replacement;
Vicese WU278 brushless motor is brushless motor, no need to replace the carbon brush, but also with a reversal stop patent technology, very durable!
