Abstract

A power nutrunner having a housing (10,11) with a rotation motor, a power transmitting gearing (18), and an output spindle (12), wherein a rotation sensing means (26,27) is associated with the output spindle (12) and arranged to deliver equidistantly generated pulse signals to an evaluation unit to detect undesirable irregularities in the rotational movement of the output spindle (12) caused by deficiencies of the gearing (18).
