Abstract: An impact power tool includes a housing, a motor, a controller, an impact mechanism configured to be driven by the motor, and an output spindle configured to receive rotational impacts from the impact mechanism to rotate the output spindle. The controller is configured to detect a first impact of the rotational impacts or to detect when the motor speed drops below a speed threshold value. The controller is configured to control the motor to have a first non-zero target rotational speed using closed loop control for a predetermined time period after the first impact is detected or when the motor speed dropping below the speed threshold value is detected. The controller is configured to control the motor to have a second non-zero target rotational speed using the closed loop control after the predetermined time period. The first non-zero target rotational speed is less than the second non-zero target rotational speed.

Abstract: An impact power tool includes a brushless motor, a power switch, an output spindle, and an impact mechanism configured to selectively apply rotational impacts to the output spindle when a torque on the output spindle exceeds a torque threshold. A controller is configured to control power delivery to the motor to selectively cause the motor to operate in a first mode for installing a fastener or in a second mode for removing a fastener. In the first mode, the controller is configured to control the motor with a first conduction band value and a first advance angle value during a first time period until a first parameter is reached, and to control the motor with a second conduction band value and a second advance angle value, at least one of which is greater than the first conduction band value and the first advance angle value, after the first time period.

Abstract: A power tool includes a housing, a brushless motor received in the housing, a power switch coupled to the housing and actuatable by a user, a controller configured to control power delivery to the motor in response to actuation of the power switch, and an output spindle configured to rotate when the motor is energized. The controller is configured to maintain an amount of current delivered to the motor to be less than or equal to a current limit by turning off or reducing power to the motor for a time period if the current exceeds the current limit and then restarting power delivery to the motor. The time period is greater than the duration of one full current cycle.

Abstract: The present disclosure is directed to a convertible battery pack having an improved switching circuit. The switching circuit includes a converter element having a plurality of contacts positioned in the converter element such that as the converter element slides within the battery pack the contacts move from a first position to engage a first set of contact pads to a second position to engage a second set of contact pads. The converter element includes a pair of springs for each of the plurality of contacts that force the contacts into engagement with the contact pads but also allow the contacts to adjust for imperfections in the contact pad surface or the manufacturing tolerances of the contact pads or a support board that holds the contact pads.
