Which brushless motor is used for power tools?

Electric tools are a type of tool that converts electrical energy into mechanical energy and performs work on components through rotational motion. Common electric tools include electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, electric planers, etc. At present, in order to ensure smooth starting of lithium battery pack handheld power tools, most of the motors used still choose brushless motors instead of brushed motors.

So why choose brushless motors for electric tools?
Brushless motors are the core of electric tools. Due to the changes in load and speed during operation, and the need for good torque output at both high and low speeds, the vast majority of brushless motors choose Hall type control. The controller determines the rotor position of the motor through feedback encoding from Hall sensors, thereby controlling the continuous operation of the motor.

Brushless motors have eliminated the carbon brush reversing mechanism, which has the advantages of low cost, long service life, and high reliability in engineering applications. In addition, compared with brushed motors and brushless motors, brushless motors improve motor power utilization, reduce faults and maintenance costs in the later stage.
