Abstract
A power tool includes a motor having an output shaft that defines an axis, a drive train connected to the output shaft and operable to drive a tool output and a housing at least partially surrounding the motor and the drive train. The power tool further includes a reference disk fixed to the housing, a collar including internal teeth that engage at least a portion of the drive train and a torque transducer having a hub, a web and a rim. The torque transducer is positioned between the collar and the reference disk such that the rim is connected to the collar and the hub is connected to the reference disk. The web defines a first thickness measured parallel to the axis and the rim defines a second thickness measured in a radial direction with respect to the axis, such that the second thickness is greater than the first thickness.
