Abstract: A power tool includes a button useful to select a direction of rotation of the power tool. The button can be used to select between forward, reverse, and neutral. The power tool includes a housing which is coupled with an abutment structure which engages with the button. A sawtooth engagement is formed between the abutment structure and the button. The sawtooth engagement can be asymmetric in shape to provide different force vectors depending on whether the button is pushed in a first or a second direction. The sum of the resistive forces can be the same whether the button is pushed in the first or second direction, owing to the asymmetric forces caused by the sawtooth engagement which make up for differences in other internal resistive forces.

Abstract: 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.

Abstract: An illustrative embodiment of the present disclosure provides hand-held power tool which includes a housing, a motor, and an output spindle. The housing supports a motor having a rotor configured to rotate when the motor is supplied with power. The output spindle protrudes from an output end of the housing, and is functionally coupled to the rotor such that the output spindle rotates in response to a rotation of the rotor. The housing also supports at least one electrical accessory that is connectable to an external power connector located on the housing.

Abstract: In at least one illustrative embodiment, an impact tool may comprise an impact mechanism including a hammer and an anvil. The hammer may be configured to rotate about an axis and to translate along the axis to impact the anvil to cause rotation of the anvil about the axis. The impact tool may further comprise a motor, a drive train, an inertial sensor, and an electronic controller. The drive train may be configured to transfer rotation from the motor to the hammer of the impact mechanism. The inertial sensor may be configured to sense an acceleration of the drive train along the axis. Further, the electronic controller may be operably coupled to the motor and to the inertial sensor and configured to decrease a rotational speed of the motor in response to determining that the acceleration of the drive train has exceeded a threshold acceleration.

Abstract: 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.
