Abstract
A nail gun includes a housing; an electric motor disposed in the housing; a battery pack configured to power the electric motor; a firing assembly configured to be capable of moving from an initial position to a firing position to drive a nail into a workpiece and moving from the firing position to the initial position within a nailing cycle; a parameter detection unit connected to at least the electric motor and configured to detect at least a working parameter of the electric motor; and a controller connected to at least the parameter detection unit. The controller is configured to, if the working parameter of the electric motor in a startup process is less than or equal to a parameter threshold, restrict a maximum duty cycle of a startup control signal to being less than or equal to a duty cycle threshold.
