Abstract: A power tool includes a housing and a brushless motor. The brushless motor includes a rotor and a stator and is configured to rotate a motor shaft to rotate a motor shaft to produce an output. The output of the brushless motor is adjustable based on a plurality of selectable field weakening modes. The power tool includes a battery pack receptacle configured to receive a battery pack, a power circuit configured to receive power from the battery pack and supply power to the brushless motor, and an electronic processor electrically connected to the motor, the battery receptacle, and the power circuit. The electronic processor is configured to determine a tool parameter associated with the output of the power tool, and determine a motor parameter based on the determined tool parameter. The motor parameter is associated with one of the plurality of selectable field weakening modes.

Abstract: An impact power tool including a housing, a motor supported by the housing, a gear assembly driven by the motor, and an impact assembly driven by the gear assembly. The impact mechanism includes a camshaft, an anvil, and a hammer. The camshaft is coupled to the output of gear assembly and rotates about a rotation axis. The anvil is rotatably supported by the housing and can receive a tool bit. The hammer rotates and moves axially along the camshaft and is configured to selectively impact the anvil. When a reaction torque is greater than a threshold value is applied to the anvil, the hammer moves in a first direction away from the anvil and simultaneously compresses a compressible fluid. At a maximum distance from the anvil, the compressible fluid begins to exert a restoring force on the hammer and moves the hammer in a second direction towards the anvil.
