Abstract
A power tool including a housing, a brushless direct current (DC) motor, an impact mechanism including a hammer and an anvil, an output drive device, a position sensor, and a controller. The power tool also includes a target positioned on a shaft, a magnetic shield positioned on the shaft between the target and the anvil, and a position sensor. The position sensor includes an inductive sensor, a first transmitting circuit trace, and a first receiving circuit trace. The controller is configured to calculate a drive angle based on the determined position of the anvil, and control the brushless DC motor based on the drive angle of the anvil.
