    Abstract: A power tool and a method of operating a power tool including a motor, a clutch collar including a plurality of settings, a wireless transceiver operable to form a wireless connection with a remote device, and a processor coupled to the clutch collar and the wireless transceiver. The processor receives, via the wireless transceiver, a mapping including a plurality of torque levels corresponding to the plurality of settings. The processor detects that the clutch collar is set to a setting of the plurality of settings. The processor is further determines the torque level for the setting from the mapping and detects, during the operation of the power tool, that a torque of the power tool exceeds the torque level. The processor is also configured to generate an indication that the torque exceeds the torque level. The indication may include flashing a light, ratcheting the motor, and stopping the motor.

    Abstract: A power tool including a housing, a controller within the housing, and a brushless motor within the housing and controlled by the controller. The brushless motor including a stator assembly including a stator core having stator laminations with an annular portion and inwardly extending stator teeth. The stator assembly defines a stator envelope in an axial direction extending between axial ends of stator end caps of the stator assembly. The brushless motor further includes a rotor assembly including a rotor core having rotor laminations and defining a central aperture that extends in the axial direction and that receives a shaft, and a position sensor board assembly including position sensors and configured to provide position information of the rotor core to the controller. The rotor assembly and the position sensor board assembly are provided at least partially within the stator envelope.

    Abstract: An electrical device including a first battery pack receptacle, a second battery pack receptacle, and circuitry including an electronic processor. The first battery pack receptacle is configured to receive a first battery pack. The second battery pack receptacle is configured to receive a second battery pack. The second battery pack is electrically connected in a series-type configuration with the first battery pack. The circuitry is configured to alter a first signal output from the electronic processor to at least one selected from a group consisting of the first battery pack and the second battery pack, and alter a second signal received by the electronic processor from at least one selected from the group consisting of the first battery pack and the second battery pack.

    Abstract: A brushless direct current motor for a power tool. The motor includes a stator assembly including a stator core having stator laminations with an annular portion and inwardly extending stator teeth. The motor also includes a rotor assembly including a rotor core having rotor laminations and defining a central aperture that receives an output shaft. The rotor assembly also includes a rotor end cap on a first side of the rotor core having a bearing holder and defining a channel, wherein the channel is open on a side of the rotor end cap facing the rotor core. The motor further includes a bearing provided in the bearing holder that couples the rotor end cap to the output shaft and a position sensor board assembly provided in the channel of the rotor end cap and configured to provide position information of the rotor core to a motor controller.

    Abstract: An expanding tool comprising: an actuator comprising a cylindrical housing that defines an actuator housing cavity; a primary ram disposed within the actuator housing cavity, the primary ram defining an internal primary ram cavity; a secondary ram disposed within the internal primary ram cavity; a cam roller carrier coupled to a distal end of the secondary ram; a drive collar positioned within a distal end of the actuator housing cavity; a roller clutch disposed within an internal cavity defined by an inner surface of the drive collar; a shuttle cam positioned between the roller clutch and a distal end of the primary ram; an expander cone coupled to the primary ram; and an expander head operably coupled to the drive collar. When triggered, the actuator first rotates the expander head and then the actuator expands the expander head.
