摘要： A battery pack that is connectable to and supportable by a power tool (e.g., a hand-held power tool). The battery pack includes a top housing having a support member. The support member of the battery pack top housing is configured or operable to reinforce a support portion of the battery pack that is used to connect the battery pack to the power tool. By reinforcing the support portion of the battery pack, an interface between the battery pack and the power tool is able to withstand greater forces (e.g., from vibrations caused by the power tool).

摘要： A power tool includes a housing, a battery connection portion supported by the housing, a drive mechanism configured to operate a working element, and a brushless DC motor positioned within the housing and connected to the drive mechanism. The motor includes a rotor, stator surrounding the motor, and an output shaft fixed to the rotor such that movement of the rotor is transmitted to the output shaft. The motor also includes a fan coupled to the output shaft to rotate with the output shaft and the rotor, and a brass bushing fixed to the output shaft to rotate with the rotor and the output shaft relative to the stator. The bushing includes a balancing feature.

摘要： A power tool with a combined printed circuit board (PCB) that reduces internal wiring of the power tool and provides a large amount of air flow to internal components. In some instances, the combined PCB has a surfboard shape and includes a motor control unit and power switching elements (Field Effect Transistors or FETs). The combined surfboard PCB is located above the trigger, but below the motor and drive mechanism. In other instances, the combined PCB has a doughnut shape and is located coaxially with a motor shaft. The combined PCB may be positioned between a doughnut-shaped control PCB and the motor.

摘要： The present invention relates to a battery pack including a housing, a latch mechanism, a printed circuit board connected to electrical terminals, and an internal frame. The housing includes a first and second portion. The first portion includes openings that receive the latch mechanism and openings that receive the terminals. The battery pack also includes a latch cover that protects against water infiltrating between the openings and the latch mechanism, and a terminal cover that protects against water infiltrating between the first housing portion and the terminals. Water that enters the battery pack is directed to the bottom of the battery pack. The water is then drained through openings in the lower housing portion. The internal frame includes openings that secure batteries within the lower housing portion with the help of wedges that are positioned in between adjacent rows of batteries.

摘要： An electric motor for use with a power tool includes a rotor having a body and a plurality of magnets coupled to the body, a stator having a plurality of electromagnetic coils surrounding the rotor, and an output shaft coupled to the rotor for rotation with the rotor. The output shaft defines a longitudinal axis about which the rotor rotates. The motor also includes a balancing member coupled to the output shaft for rotation with the rotor. The balancing member substantially balances a mass of the rotor about the longitudinal axis to reduce vibrations of the electric motor during use.
