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 transducer assembly for use in a power tool including a housing, a motor, an output shaft that drives a workpiece about a central axis, and a transmission. The transducer assembly includes a transducer positioned between the motor and the transmission. The transducer including an inner hub being rotationally affixed to the housing, an outer rim affixed to a rotatable component of the transmission, a plurality of webs extending radially outward from the inner hub to the outer rim, and a sensor affixed to each of the webs for detecting strain of each of the webs in response to a reaction torque applied to the transmission from the output shaft. A width of each of the webs gradually tapers from at least one of the outer rim or the inner hub toward a midpoint of each of the webs in a direction perpendicular to the central axis.

Abstract: A power tool includes a tool housing defining a cavity and a pocket formed in a wall of the tool housing. A motor is positioned within the cavity, and a trigger mechanism is moveably coupled to the tool housing. A speed selector switch is positioned within the pocket, the speed selector switch including a push-button operable to receive a speed selection and a plurality of speed indicators. The speed selector switch is operable to output a speed signal based on the speed selection, and the speed indicators indicate the speed selection. The power tool further includes a controller operable to receive the speed signal from the speed selector switch, the speed signal indicative of a selected speed, receive an activation signal from the trigger switch, and operate the motor at the selected speed upon receiving the activation signal.

Abstract: A transducer assembly for use in a power tool includes a bracket affixed to a housing of the power tool and a protrusion having an arcuate outer periphery. The protrusion is offset from a central axis of the bracket and extends from the bracket in a direction parallel with the central axis. The transducer assembly also includes a transducer having an inner hub with an aperture through which a distal end of the protrusion is received. The arcuate outer periphery of the protrusion is in substantially line contact with a wall segment at least partially defining the aperture. The transducer also includes an outer rim affixed to a ring gear of the power tool, a flexible web interconnecting the inner hub to the rim, and a sensor affixed to the flexible web for detecting strain of the flexible web in response to a reaction torque applied to the ring gear.

Abstract: A rotary power tool comprises a motor, an output shaft that receives torque from the motor, a clutch positioned between the motor and the output shaft for selectively engaging the output shaft to the motor, and a transducer for detecting an amount of torque transferred through the clutch to the output shaft. The clutch is capable of being actuated from a first mode in which the output shaft is engaged to the motor, to a second mode in which the output shaft is disengaged from the motor, in response to feedback from the transducer of the detected amount of torque transferred through the clutch.
