Abstract: A rotary power tool may include a main housing, a motor positioned within the main housing, a handle extending from the main housing, a trigger that is configured to activate the motor when depressed, and a control board disposed within the handle and including a microcontroller (MCU), a first Hall sensor, and a second Hall sensor. The trigger includes a trigger body, a holder fixed to the main housing, the trigger body being movable relative to the holder along a longitudinal axis, an arm fixed to the trigger body and having a magnet holder that receives a magnet, and a spring for biasing the trigger body away from the holder. The first Hall sensor and the second Hall sensor are configured to detect depression of the trigger and emit signals to the MCU for controlling operation of the motor.

Abstract: A trigger assembly, for use with a power tool having an electric motor, includes a trigger, a conductor coupled for movement with the trigger, and a printed circuit board. The printed circuit board has an inductive sensor thereon responsive to relative movement between the conductor and the inductive sensor caused by movement of the trigger. An output of the inductive sensor is used to activate the electric motor.

Abstract: A rotary power tool including a gear case, an output shaft extending from the gear case, and a drive mechanism configured to provide torque to the output shaft, causing the output shaft to rotate. The rotary power tool further includes a clutch mechanism between the output shaft and the drive mechanism. The clutch mechanism includes a compression spring and is configured to limit the amount of torque provided by the output shaft. The rotary power tool further includes a sensor positioned on a neck portion of the gear case subject to strain imparted by the compression spring, and an electronic control unit configured to receive an output signal from the strain gauge and determine a torque setting of the clutch mechanism based on the output signal.

Abstract: A rotary impact tool includes a housing, an electric motor supported in the housing, and an impact mechanism for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece. The impact mechanism includes an anvil and a hammer that is both rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil. The hammer is configured to rotate about an axis in a rotational direction when imparting the consecutive rotational impacts upon the anvil. The impact mechanism also includes a spring for biasing the hammer in an axial direction toward the anvil, and a means for biasing the anvil in the rotational direction about the axis.

Abstract: A method of controlling a rotary impact tool includes activating a motor to provide torque to a drive assembly, providing rotational impacts to a torque stick coupled to an anvil of the drive assembly in response to a reaction torque on the drive assembly exceeding a threshold value, and sensing a position of the anvil with a position sensor. The position sensor transmits a first signal indicative of the anvil rotating in a first direction and a second signal indicative of the anvil rotating in a second direction, where the second direction is a rebound angle of the anvil. The method further includes calculating a torque transferred from the torque stick to a workpiece by multiplying the rebound angle by a torsional stiffness value of the torque stick and deactivating the motor in response to the torque exerted on the workpiece being substantially equal to a torque limit.

Abstract: A trigger assembly for a power tool includes a housing, a moveable plunger extending from a surface of the housing, the movable plunger includes a first end disposed externally from the housing and a second end disposed internally within the housing. The trigger assembly further includes a trigger shoe coupled to the first end of the moveable plunger, and an arm including a first side that is moveably connected to the second end of the moveably plunger and a second side that is coupled to a magnet. The trigger assembly also includes a sensor configured to sense a magnetic field of the magnet. Movement of the trigger shoe rotates the magnet, and alters the magnetic field sensed by the sensor.
