Abstract: A powered fastener driver includes a housing, a cylinder within a cylinder support portion of the housing, a piston movable within the cylinder from a top-dead-center (TDC) position to a driven or bottom-dead-center (BDC) position, a driver blade attached to the piston for movement therewith, a lifter operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position, a drive unit operably coupled to the lifter, and a printed circuit board positioned within the housing. The printed circuit board includes a plurality of power switches and defines a length and a width. A vibration attenuating damper is positioned between the housing and the printed circuit board. The damper is positioned along the length of the printed circuit board and configured to support the printed circuit board within the housing.

Abstract: A power tool including a housing, a motor at least partially positioned within the housing, a driver blade extending along a driving axis, and a cam assembly including a cam that is configured to rotate about a rotational axis to move the driver blade. The cam includes a target that rotates with the cam. A sensor is configured to detect the target when the target is at a predetermined rotational position of the cam. A controller is connected to the motor and the sensor. The controller is configured to receive a signal from the sensor indicating that the target is at the predetermined rotational position of the cam, compare a motor parameter to a threshold value, and initiate a speed ramp down in response to the target being at the predetermined rotational position of the cam and the motor parameter being greater than or equal to the threshold value.

Abstract: A powered fastener driver including a housing, a cylinder, a piston movable within the cylinder from a TDC position to a BDC position, a driver blade attached to the piston for movement therewith along a driving axis from the TDC position toward the BDC position for driving a fastener into a workpiece, a lifter operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position, a drive unit operably coupled to the lifter, and a printed circuit board (PCB) positioned within the housing. The PCB receives electrical current from the battery pack and includes power switches for commutating the motor. The PCB defines a length and a width, and a vibration attenuating damper is positioned between the housing and the printed circuit board. The damper is positioned along the length of the PCB and is configured to support the PCB within the housing.

Abstract: A power tool includes a housing having a motor housing portion and a handle portion. A motor having a motor axis is positioned within the motor housing portion. The power tool further includes a first printed circuit board positioned within the motor housing portion. The first printed circuit board intersects the motor axis. The power tool also includes a second printed circuit board positioned within the motor housing. The second printed circuit board intersects the motor axis. The second printed circuit board includes a conductive high impedance trace that is configured to interrupt electric power to the motor in response to a current that exceeds a current limit.
