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.

Abstract: Simulated bog-down system and method for power tools. One power tool according to an example embodiment includes a power source and a motor selectively coupled to the power source. The motor includes a rotor and stator windings. The power tool includes an actuator configured to generate a drive request signal and a power switching network configured to selectively couple the power source to the stator windings of the motor. The power tool includes an electronic processor coupled to the power source, the actuator, and the power switching network. The electronic processor is configured to detect a load on the power tool and compare the load to a threshold. The electronic processor is configured to determine that the load is greater than the threshold, and to control the power switching network to simulate bog-down in response to determining that the load is greater than the threshold.

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 programmable power tool and method and systems of programming a power tool using wireless communication. An external device having a processor and a transceiver establishes a communication link with the power tool. The external device receives, with the transceiver, a first mode profile stored on the power tool. The first mode profile is defined by a profile type and a first value associated with a parameter for executing the profile type. The external device displays a control screen including the profile type and the parameter at the first value, and receives a user input. The external device generates, in response to the user input, a second mode profile by modifying the parameter to be at a second value. The external device transmits, with the transceiver, the second mode profile to the power tool.

Abstract: A method for expanding features of a gas engine replacement device that drives power equipment including controlling, by an electronic processor of the gas engine replacement device, a power switching network to selectively provide power from a battery pack to rotate a motor of the gas engine replacement device. A module interface of the gas engine replacement device receives an external electronics module. A type of the external electronics module received by the module interface is detected by the electronic processor of the gas engine replacement device. The gas engine replacement device is configured by the electronic processor based on the type of the received external electronics module. The electronic processor communicates with the external electronics module via the module interface.
