Abstract
A power tool with an impact mechanism and that is controlled based on a drive angle from impacting. The power tool includes a housing, a brushless direct current (DC) motor within the housing, an impact mechanism, and an output drive device. The brushless DC motor includes a rotor coupled to a motor shaft to produce a rotational output. The impact mechanism includes a hammer coupled to the motor shaft, and an anvil that receives impacts from the hammer and drives an output device. The power tool further includes a position sensor that senses a position of the rotor and a controller coupled to the position sensor. The controller detects an impact of the impact mechanism, calculates a drive angle of the anvil caused by the impact based on output from the position sensor, and controls the brushless DC motor based on the drive angle.
