Abstract: Systems and methods for implementing an electronic clutch in a powered fastener driver. One fastener driver includes a motor, a trigger, a position sensor, a speed sensor, and a controller. The position sensor is configured to sense a position of the lifting assembly. The speed sensor is configured to sense a speed of the motor. The controller is configured to provide power to the motor. The controller is configured to receive speed signals from the speed sensor indicative of the speed of the motor, and determine whether the speed of the motor has dropped by a speed drop threshold within a first period of time. The controller is configured to activate an electronic clutch to electronically brake the motor for a second period of time. In response to the second period of time having passed, the controller is configured to provide power to the motor.

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.

Abstract: A power tool includes a motor, a speed sensor configured to sense a speed of the motor, and a controller connected to the motor and the speed sensor. The controller is configured to provide power to the motor, determine a first command based on the speed of the motor, determine, while in a first operating mode, whether the first command is greater than or equal to a first limit, determine, while in the first operating mode, a PWM duty cycle ratio based on the first limit, determine, while in a second operating mode, whether a parameter command is greater than or equal to a parameter limit, while in the second operating mode and when the parameter command is greater than or equal to the parameter limit, the PWM duty cycle ratio based on the parameter limit, and drive the motor based on the PWM duty cycle ratio.

Abstract: A power tool includes a housing enclosing a motor and a sensor. The sensor is configured to control operation of the motor. The power tool includes an output device driven by the motor, a mount coupled to the sensor, and an actuator removably coupled to the mount. The actuator is slidable along the mount to couple the actuator to the mount.
