# Electronic clutch for power tools

## Abstract

Systems and methods for electronically limiting torque in a power tool. One power tool includes a motor, a trigger, and a controller connected to the trigger and the motor. The controller is configured to provide, in response to actuation of the trigger, power to the motor, determine a speed of the motor, activate the electronic clutch, in response to determining that the speed of the motor has dropped by the speed drop threshold within the first period of time, to electronically brake the motor for a second period of time, and provide, in response to the second period of time having passed, power to the motor.
