More Information
Summary:The present invention provides a control method and apparatus for an electric tool, and further provides an electronic tool, which relates to the field of automatic control of electric tools. The method comprises: Obtaining parameters characterizing an output shaft load during a running process of an electric tool; calculating the average values of the parameters characterizing an output shaft load according to a composite average algorithm, wherein the composite average algorithm comprises a combination of at least two average algorithms; calculating slope values of the parameters characterizing the output shaft load according to the average values of the parameters characterizing the output shaft load; and interrupting torque output of the electric tool according to the slope values of the parameters characterizing the output shaft load.
