Abstract
An electric motor for portable machine tools, comprising an output shaft for operating, means for sensing the speed of said output shaft;
means for sensing the magnitude and the phase of the input voltage of the electric motor itself; means for sensing the electric current absorbed by the load, microprocessor means programmed for processing the detected values sensed by said means for sensing; means for generating an acceleration ramp at the starting; means for generating a deceleration ramp at the stopping, as well as means for generating the cruise speed of the tool, voltage controlled by said microprocessor in response to said detected values processed by itself, and means for controlling the forward running, reverse running and the run storing.
