摘要: An impact tool is provided which includes a drive source configured to rotate an output drive. A hammer is movable in a first direction to apply a rotational impact force on an anvil which rotates the output drive. A first hammer angle sensor set to a first signal channel and located proximate to a surface of the hammer. A plurality of regularly spaced targets are located on the surface of the hammer. Each of the plurality of regularly spaced targets are detectable by the first hammer sensor. And detection of one or more of the plurality of regularly spaced targets by the first hammer sensor indicates movement of the hammer.

摘要: A power tool and method of determining torque is provided. The method of determining torque uses the energy output by the drive mechanism and the angle of rotation of the output shaft to estimate torque. The energy is determined by subtracting efficiency losses (or gains) from a nominal energy of the drive mechanism in order to improve the torque estimation.
