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.
Claims23
A power tool comprising:
- a motor;
- an impact mechanism coupled to the motor, the impact mechanism including
- 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;
- 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.
A method of operating a power tool, the method comprising:
- activating, via an electronic processor, a motor of the power tool;
- driving, via the motor, an impact mechanism of the power tool, the impact mechanism including a hammer, and an anvil configured to receive an impact from the hammer, and the impact mechanism housed within an impact case;
- detecting, with a sensor assembly, a position of one selected from a group consisting of the hammer and the anvil, the sensor assembly being housed within the impact case;
- generating, with the sensor assembly, an output signal indicative of the position of the one selected from the group consisting of the hammer and the anvil, the position detected by the sensor assembly;
- and
- controlling, via the electronic processor, the motor based on the output signal.
