Abstract: A power tool including a housing, a motor, a controller, and a trigger mechanism. The housing includes a handle housing portion and a motor housing portion. The motor is supported within the motor housing portion. The controller is disposed in the housing and is configured to control operation of the motor. The trigger mechanism is coupled to the handle housing portion. The trigger mechanism includes a trigger contact body and a sensor configured to detect a force applied on the trigger contact body and transmit a signal to the controller to energize the motor.

Abstract: A system including a power tool and a battery pack. The system includes a power tool including a housing. The housing includes a battery pack interface that includes a first battery pack terminal and a first retaining element. The power tool also includes an electric motor and a controller. The electric motor includes an inner stator, an outer rotor, and a fan. A battery pack includes a base, a stem, a second retaining element, and a single battery cell connected to a second battery pack terminal. The battery pack produces at least a 170 watt output. The stem of the battery pack is configured to be inserted into the battery pack interface of the power tool. The second retaining element is configured to engage the first retaining element. The controller is and configured to control power supplied from the second battery pack terminal to the electric motor.

Abstract: A power tool includes a housing, a rechargeable battery pack coupled to the housing, and a motor supported by the housing. The motor includes a stator assembly having a stator frame with an opening extending therethrough and a plurality of coil windings configured to be selectively powered by the rechargeable battery pack. The coil windings are positioned adjacent the opening of the stator frame. The motor further includes a rotor assembly disposed within the stator assembly and configured to rotate as the coil windings are powered by the rechargeable battery pack. Moreover, the power tool includes an output drive assembly supported by the housing. The output drive assembly extends through the opening of the stator frame to be operably coupled to the rotor assembly.
