Cordless drills with brushless motors have come out in the past ten years and have quickly developed on traditional brush models. Now, they occupy 30% to 50% of the cordless electric drill market.

The electric motor converts the supplied electrical energy into mechanical energy. Various types of motors are generally used. Among them, brushless DC motors (BLDC) have high efficiency and excellent controllability, and have been widely used in many applications. Compared with other types of motors, BLDC motors have power saving advantages.

How does a brushless motor work?Brushless motors are common in industrial applications worldwide. At the most basic level, there are brush and brushless motors, as well as DC and AC motors. You might think that a brushless motor does not contain brushes, but uses DC current.Compared with other types

What’s the advantage of a brushless motor?Cordless drills with brushless motors have come out in the past ten years and have quickly developed on traditional brush models. Now, they occupy 30% to 50% of the cordless electric drill market. "Consumer Reports" cordless drill market analyst Courtney Pen

How to repair brushless motor?Brushless motors are complex and complicated equipment. Therefore, they can stop working for a variety of reasons. Both AC motors and DC motors have similar problems. Whether it is due to lack of maintenance, wear and tear, or just due to aging, failures occur due to va
