Abstract
An impact driver, in accordance with one embodiment, includes a rotatable shaft, and a rotating driver mechanism configured to rotate the shaft. A first mass is positioned to selectively strike the rotating driver mechanism for inducing a rotation of the shaft in a first direction. A first inductor is positioned to accelerate the first mass toward the rotating driver mechanism. A computer-implemented method, in accordance with one embodiment, includes repeatedly activating a first inductor for repeatedly accelerating a first mass toward a rotating driver mechanism to selectively strike the rotating driver mechanism for inducing a rotation of a shaft in a first direction. In response to receiving an indication that rotation of the shaft is detected, the repeated activation is terminated.
