Abstract: Power tool methods and systems are provided for aligning a power tool to implement an angled cut in a workpiece. The power tool includes a first distance sensor and a second distance sensor. The power tool measures a first distance to the workpiece with the first distance sensor and a second distance to the workpiece with the second distance sensor. The power tool calculates an angle between the power tool and the workpiece based on the first and second distances, and indicates the angle via an angle output indicator of the power tool. The power tool may measure an angle between the power tool and the workpiece using a proximate edge and a distal edge of the workpiece, and indicate whether the power tool maintains a correct angle as it traverses a cut through the workpiece from the proximate edge to the distal edge.

Abstract: A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the handle, and a drive unit positioned in the drive unit support portion. The drive unit includes an output shaft extending at least partially through the handle portion. The power tool also includes a ball screw mechanism having a nut supported at least partially within the inner housing and a screw coupled to the nut for relative axial displacement therewith in response to relative rotation between the screw and the nut. Torque from the output shaft is applied to one of the nut and the screw to cause the relative rotation. The handle portion exerts a reaction torque on the inner housing in response to the relative rotation between the nut and screw to prevent the inner housing from rotating relative to the outer housing.

Abstract: A power tool includes a motor having an output shaft, an extensible member driven by the motor, a working assembly movable in response to contact with a distal end of the extensible member, a first sensor configured to detect a home position of the extensible member, a second sensor configured to detect rotation of the motor output shaft, and a controller in electrical communication with the first and second sensors. The controller is configured to drive the motor output shaft in a first rotational direction a predetermined number of revolutions counted by the second sensor, thereby displacing the extensible member from the home position. The controller is also configured to drive the motor output shaft in an opposite, second rotational direction to thereby return the extensible member until the home position is detected by the first sensor.

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: A power tool that includes a housing, a brushless motor, a power switching circuit, and an electronic controller. The brushless motor is within the housing. The brushless motor includes a rotor and a stator. The rotor is coupled to a motor shaft arranged to rotate about a longitudinal axis. The motor shaft is arranged to produce a rotational output to a drive mechanism. The power switching circuit provides a supply of power from a battery pack to the brushless motor. The electronic controller is configured to determine a parameter associated with the battery pack, assign a classification to the battery pack based on the determined parameter, and control field weakening applied to the brushless motor based on the classification of the battery pack.

Abstract: A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the outer housing, and a drive unit positioned in the drive unit support portion, the drive unit including an output member. The power tool also includes a power screw mechanism with a nut fixed relative to the outer housing and a screw coupled for co-rotation with the output member and axially movable relative to the output member. The screw is in threaded engagement with the nut such that the screw moves axially in response to rotation of the screw relative to the nut. The power tool also includes a working assembly coupled to the inner housing for movement in response to axial movement of the screw.
