Publication number: 20230150098Abstract: A rotary impact tool includes a housing, an electric motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece. An anvil has a bore defining a hexagonal cross-sectional shape and having a nominal width of 7/16 inches. A hammer is rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil. A spring biases the hammer in an axial direction toward the anvil. A battery pack has a nominal voltage of at least 18 Volts and a nominal capacity of at least 5 Ah. The rotary impact tool has an overall weight including the battery pack that is less than or equal to 7.5 pounds. A second performance ratio of the rotary impact tool, defined as (?a x RPMno-load/Inertiahammer) x (1/216,000,000) is greater than 2.Type: ApplicationFiled: January 17, 2023Publication date: May 18, 2023Inventor: Jacob P.

Publication number: 20230015954Abstract: Position sensing related to a component within a power tool. The component within the power tool is, for example, a hammer of an impact mechanism and can include one or more sensible features that allow a controller of the power tool to precisely determine the position, speed, and acceleration of the component. One or more sensors can be used to determine the rotational position of the hammer and the axial position of the hammer. The rotational position of the hammer can then be used to calculate, for example, rotational speed and acceleration of the hammer. With precise determinations of the rotational and axial position of the hammer, the controller of the power tool is able to precisely time the impact between the hammer and the anvil to optimize the impact between the hammer and the anvil (e.g., to maximize energy transfer between the hammer and the anvil).Type: ApplicationFiled: September 28, 2022Publication date: January 19, 2023Inventors: Jacob P.
