Abstract
A power tool includes a motor, an output shaft, a commutation detection device, and a controller. The commutation detection device is connected to the motor and used for obtaining commutation information of the motor. The controller is capable of outputting a control signal to control the motor to rotate. When the commutation information does not match a preset commutation condition, the control signal is adjusted based on the commutation information such that a rotational speed of the motor is maintained to be a target rotational speed.
