Abstract
A control method of an impact power tool includes: control a motor to rotate; continuously obtain a rotation speed signal based on a detecting result of a rotation speed detecting device and obtain a current signal based on a detecting result of a current detecting device; obtain a rotating time of each of rotation angles of the motor based on a variation of pulse waves of rotation speed signal and obtain the motor current based on the current signal; determine a number of impact that the impact mechanism produces based on a variation of the rotating time and a variation of the motor current; control the motor to stop rotating when the number of impact reaches a predetermined number. In this way, an output torque outputted by the impact power tool could be accurately controlled.
