Abstract: A power tool includes a housing, a motor, a switching network electrically coupled to the motor, and a printed circuit board positioned at an angle within the housing. The power tool further includes a user input configured to receive a sensitivity level for loss of control detection, a sensor configured to measure an acceleration of the housing with respect to at least two axes, and an electronic processor coupled to the switching network. The electronic processor is configured to receive one or more signals related to the acceleration of the housing of the power tool from the acceleration sensor, determine that the one or more signals exceed an acceleration threshold corresponding to the sensitivity level for loss of control detection, and control the switching network to brake the brushless DC motor in response to the one or more signals exceeding the acceleration threshold.

Abstract: A compactor includes a plate, a frame coupled to the plate, and an exciter assembly coupled to the plate and including an exciter shaft, an exciter pulley on the exciter shaft, and an eccentric weight on the exciter shaft. The compactor also includes a motor coupled to the frame and having an output shaft and a drive pulley on the output shaft, a belt wrapped around the exciter pulley and the drive pulley at a minimum tension value for transferring torque from the drive pulley to the exciter pulley, causing it to rotate, and a sensing circuit configured to detect if the tension in the belt is below the minimum tension value.

Abstract: A powered log splitter includes a support structure configured to support a log, a ram that is operable to engage and split the log, a hydraulic drive unit to actuate the ram, and a stand-alone motor unit to power the hydraulic drive unit. The stand-alone motor unit includes a housing, an electric motor located within the housing, and a battery pack removably coupled to the housing. The battery pack is configured to supply electrical current to the electric motor
