    Abstract: A power tool system includes a hydraulic power tool. The hydraulic power tool includes a hydraulic drive, a sensor, and a first electronic processor. The sensor is configured to detect an operational parameter of the hydraulic drive during an operation by the hydraulic drive. The first electronic processor is configured to store a plurality of data points based on the operational parameter detected during the operation and send the plurality of data points to an external device. The external device includes a display screen and a second electronic processor configured to receive the plurality of data points from the hydraulic power tool, control the display screen to display an expected data point for the operational parameter for the operation, and control the display screen to display an actual data curve based on the plurality of data points, the actual data curve overlaid on the expected data point.

    Abstract: A power tool including a three-phase DC motor, a power switching network, a power source, and an electronic processor. A first phase of the motor is connected between a first high side electronic switch and a first low side electronic switch, and between a second high side electronic switch and a second low side electronic switch. The first high side electronic switch is parallel to the second high side electronic switch, and the first low side electronic switch is parallel to the second low side electronic switch. The electronic processor receives an indication to stop the motor, and deactivates the first high side electronic switch and the first low side electronic switch, and activates the second high side electronic switch and the second low side electronic switch such that the back-electromagnetic force generated by the motor is connected in a second polarity relative to the power source.

    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.

    Abstract: A power tool and method of detecting impacts of a power tool that includes a motor driving a hammer to impact an anvil. A motor control unit is configured to determine a motor characteristic indicative of a speed of the motor. When the motor characteristic indicates that the speed of the motor is below a speed threshold, the motor control unit employs an acceleration-based technique to detect a first impact based on a change in motor acceleration and generate a first impact indication in response to detecting the first impact. When the motor characteristic indicates that the speed is above the speed threshold, the motor control unit employs a time-based technique to detect a second impact based on an elapsed time and generates a second impact indication in response to detecting the second impact.
