Abstract: A rotary impact tool including a motor housing, an electric motor supported in the motor housing, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece. The drive assembly includes an anvil including an anvil lug, and a hammer that is both rotationally and axially movable relative to the anvil. The hammer includes a hammer lug for imparting the consecutive rotational impacts upon the anvil lug. The rotary impact tool further includes a first printed circuit board assembly including an anvil sensor, a first carrier supporting the first printed circuit board assembly, a second printed circuit board assembly including a hammer sensor, and a second carrier supporting the second printed circuit board assembly.

Abstract: A power tool includes a housing, a motor mounted within the housing and including a stator with an outer diameter and a rotor having a shaft configured to rotate about an axis relative to the stator. The power tool also includes a gear assembly operably coupled to the motor and including a ring gear fixed relative to the housing and planet gears meshed with the ring gear. A drive assembly is operably coupled to the gear assembly to receive torque from the shaft through the gear assembly. The power tool also includes a rear bearing rotatably supporting a rearward portion of the shaft and a forward bearing rotatably supporting a forward portion of the shaft. A distance measured between a front edge of the rear bearing and a rear edge of the forward bearing is less than the outer diameter of the stator.

The drive assembly includes an anvil including an anvil lug and a hammer that is both rotationally and axially movable relative to the anvil. The hammer includes a hammer lug for imparting the consecutive rotational impacts upon the anvil lug. The rotary impact tool further comprises a printed circuit board assembly including a sensor that is configured to detect rotation of the anvil. The printed circuit board assembly is spaced from the anvil to define an axial gap therebetween.
