1. A power tool comprising:
- a motor;
an impact mechanism coupled to the motor, the impact mechanism includinga hammer driven by the motor andan anvil positioned at a nose of the power tool, and configured to receive an impact from the hammer, wherein the anvil includes an engagement structure to engage with the hammer;
an impact case housing the anvil and the hammer;
a sensor assembly positioned in the impact case, the sensor assembly includes an output position sensor configured to generate an output signal indicative of one selected from a group consisting of a position of the hammer and a position of the anvil; and
an electronic processor coupled to the output position sensor and to the motor, the electronic processor configured to;
control the motor based on the output signal from the output position sensor,wherein the output position sensor includes an inductive sensor, andwherein the inductive sensor detects a rotational position of the engagement structure.

Abstract
A power tool including a motor and an impact mechanism. The impact mechanism is coupled to the motor and includes a hammer driven by the motor, and an anvil positioned at a nose of the power tool, and configured to receive an impact from the hammer. The power tool also includes a sensor assembly positioned at the nose of the power tool, and an electronic processor. The sensor assembly includes an output position sensor configured to generate an output signal indicative of a position of the hammer or the anvil. The electronic processor is coupled to the output position sensor and to the motor, and is configured to operate the motor based on the output signal from the output position sensor.
