摘要： A power tool is provided that, in one version, includes a front housing that supports an output drive, and a back cap located opposite the front housing. The back cap receives at least one fastener of the plurality of fasteners. A motor housing supports a motor and is located between the front housing and the back cap. The motor includes a rotor that is configured to rotate about a motor axis to drive rotation of the output drive. The fastener is disposed through the back cap, and secures to the front housing coupling the front housing, the motor housing, and the back cap together.

摘要： A hand-held power tool is provided that includes a housing assembly, an output spindle, and a motor endbell. The housing assembly supports an electric motor having a rotor configured to rotate when the electric motor is supplied with power. The output spindle protrudes from an output end of the housing assembly, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The motor endbell is located on the housing assembly adjacent the electric motor and opposite the output spindle. An illustrative controller is operable to determine phases of a fastening operation in which the hand-held power tool is operating. The phases of the fastening operation of the hand-held power tool include two phases including: (1) a continuous run phase and (2) an impacting phase.

摘要： A hand-held power tool is provided that includes a motive source, a user interface, and one or more sensors. The motive source includes a printed circuit board (PCB) configured to support electrical components of the motive source. The user interface is movable between a plurality of mode positions to select one of a plurality of operational modes of the motive source. And one or more sensors are mounted on the PCB and are configured to detect the plurality of mode positions of the user interface.

摘要： A hand-held power tool is provided that includes a housing, a motive source, a front endbell, an output shaft, a front housing, and a gear set assembly. The output shaft protrudes from an output end at the front endbell of the housing. The output shaft is also functionally coupled to the motive source such that the output shaft rotates in response to activation of the motive source when the motive source is supplied with power. The gear set assembly is located in an interior space of the front housing, and is configured to transfer rotation from the motive source to an output spindle. The gear set assembly also includes a ring gear that surrounds a portion of the output shaft and abuts the front endbell of the housing. A set of piloting features is provided that is configured to prevent movement of the ring gear relative to the motive source and the front housing, or the front housing relative to the housing.

摘要： In at least one illustrative embodiment, a power tool may comprise an electric motor comprising a rotor configured to rotate about an axis, a stator assembly including at least three windings arranged around the rotor, and at least three lugs affixed to the stator assembly, where each of the lugs is electrically coupled to one or more of the windings. The lugs may all be arranged to one side of a plane that passes through the axis. The power tool may further comprise at least three electrical wires, where each of the electrical wires is removably coupled to one of the lugs, and a control circuit configured to supply electrical power to the windings, via the electrical wires and the lugs, to drive rotation of the rotor about the axis.
