Abstract
An electric power tool, configured to perform tightening operations where torque is delivered in a series of pulses, includes an electrical motor adapted to drive a rotating shaft of the electric power tool, and an angle sensor for sensing a parameter related to an angular displacement of the electric power tool. The electric motor is adapted to be fed with a train of controlled current pulses. The electric power tool is adapted to control a current supplied in the current pulses based at least in part on an output signal from the angle sensor to not exceed a limit threshold value for the parameter related to an angular displacement of the electric power tool.
