资源简介：
A power tool is provided including a brushless direct-current (BLDC) electric motor having a stator and a rotor. The power tool includes power switches including high-side switches and low-side switches disposed on a direct-current (DC) bus line between a power supply and the electric motor， and a controller configured to electronically brake the motor by simultaneously closing the high-side switches or the low-side switches to electrically short the stator windings. The controller is configured to monitor a voltage of the DC bus line (608)， and if the voltage of the DC bus line is lower than a voltage threshold (610)， execute electronic braking by toggling between closing the high-side switches and closing the low-side switches over braking cycles (614)， and if the voltage of the DC bus line is greater than the voltage threshold (610)， execute braking by closing only the high-side switches or the low-side switches over the braking cycles (620).
