Abstract: Power tools described herein include an electric motor, a driver blade, a trigger switch, a safety switch, and an electronic controller. The electronic controller is connected to the electric motor, the trigger switch, and the safety switch. The electronic controller is configured to initiate a retraction cycle by controlling the electric motor to move the driver blade from a first position to a second position, determine a position of the driver blade during the retraction cycle, initiate, in response to the position of the driver blade exceeding a first threshold, a braking cycle at the electric motor, and abort, in response to detecting a first activation of the trigger switch and a second activation of the safety switch, the braking cycle.

Abstract: A power tool that includes a housing, a brushless motor, a power switching circuit, and an electronic controller. The brushless motor is within the housing. The brushless motor includes a rotor and a stator. The rotor is coupled to a motor shaft arranged to rotate about a longitudinal axis. The motor shaft is arranged to produce a rotational output to a drive mechanism. The power switching circuit provides a supply of power from a battery pack to the brushless motor. The electronic controller is configured to determine a parameter associated with the battery pack, assign a classification to the battery pack based on the determined parameter, and control field weakening applied to the brushless motor based on the classification of the battery pack.

Abstract: A power tool including a housing, a motor at least partially positioned within the housing, a driver blade extending along a driving axis, and a cam assembly including a cam that is configured to rotate about a rotational axis to move the driver blade. The cam includes a target that rotates with the cam. A sensor is configured to detect the target when the target is at a predetermined rotational position of the cam. A controller is connected to the motor and the sensor. The controller is configured to receive a signal from the sensor indicating that the target is at the predetermined rotational position of the cam, compare a motor parameter to a threshold value, and initiate a speed ramp down in response to the target being at the predetermined rotational position of the cam and the motor parameter being greater than or equal to the threshold value.
