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.
