Abstract: Power tools described herein include a tool output, a motor driving the tool output, a battery pack interface, a power switching network coupled between the battery pack interface and the motor, and a controller coupled to the power switching network to control operation of the motor. The controller is configured to operate the motor at a no-load speed at startup and detect a load state of the power tool. The load state indicates whether the power tool is in a loaded state or an unloaded state. The controller is also configured to incrementally ramp up a speed of the motor from the no-load speed to a selected speed when the power tool is in the loaded state and incrementally ramp down the speed of the motor from the selected speed to the no-load speed when the power tool is in the unloaded state.

Abstract: A power tool comprising a power tool housing and a motor within the power tool housing. The motor including a rotor and a stator, the rotor coupled to a motor shaft to produce a rotational output. The power tool further includes a sensor within the power tool housing, the sensor configured to sense a free fall of the power tool, generate an output signal related to the sensed free fall. The power tool further includes a controller including a processor and a memory, the controller configured to receive the output signal from the sensor, detect the free fall of the power tool based on the output signal from the sensor, and brake the motor when the free fall of the power tool is detected.

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 powered fastener driver includes a housing, a cylinder within the housing, the cylinder containing a pressurized gas, a piston within the cylinder and movable from a top-dead-center position to a bottom-dead-center position, a driver blade movably coupled to the piston, a lifter, a drive unit configured to provide torque to the lifter, and a sensor. The driver blade has a plurality of teeth defining a predetermined number of edges. The sensor is configured to detect an edge of one or more of the plurality of teeth and a controller in communication with the drive unit and the sensor. The controller is configured to count a number of edges detected by the sensor, compare the number of detected edges to the predetermined number of edges, and stop the drive unit when the number of detected edges is less than the predetermined number of edges.
