Tips: Brushless cordless electric wrench vs. brushed cordless electric wrench
Battery powered electric wrenches bring great convenience to the vast number of maintenance workers. The cordless electric wrenches is equipped with brushed motor or brushless motor. So which one is better for brushed or brushless electric wrench good? Obviously, the brushless electric wrench greatly reduces the failure rate.
What are the differences between a brushless electric wrench and a brushed electric wrench? The brushless electric wrench relies on a digital circuit to control the commutation and deceleration and speed regulation of the electric wrench. The brushless electric wrench does not use the mechanical carbon brush no longer, which greater extend its service life. In theory, the life of the brushless electric wrench can reach 20 years, while the brushed electric wrench cannot reach. The brushless electric wrench no longer uses the gear reducer, which avoids the loss of efficiency in the gear transmission, so that the efficiency can reach 80-85%, and the noise is greatly reduced.
