METHOD AND CORRESPONDING APPARATUS FOR CONTROLLING ELECTRICAL IMPULSE SCREW DRIVER AS FUNCTION OF INSTANTANEOUS ROTATION FREQUENCY OF MOTOR THEREOF

摘要

The present invention relates to a method for controlling a discontinuous screw driver device including an electric motor connected to a terminal unit capable of rotating a rotor, wherein the motor is provided with power with a continuous power voltage pulse. According to the present invention, the method comprises a step of determining an instantaneous power voltage of the motor during each power voltage pulse, wherein the step at least comprises: a first step of measuring an instantaneous rotation frequency of the rotor in real time; a second step of determining a voltage component of the power voltage pulse which belongs to the instantaneous rotation frequency; and a third step of determining a voltage of the power voltage pulse by integrating a voltage value which depends on the instantaneous rotation frequency of the rotor.;COPYRIGHT KIPO 2018
