摘要：The invention concerns an electric drive device for medical applications,
especially for driving drills, cutting instruments and screw drivers. Such endo-instrumentshave predetermined working rotation areas and comprise maximally permissible torqueload limits according to the materials thereof. The drive device is equipped with astepping motor in order to avoid exceeding the torque load limits. The stepping motordisconnects when the maximum torque limit of the stepping motor is fixed below thetorque load limit of the instrument. In order to precisely set the torque load limit, acalibration is carried out within the limits of a no-load operation during which theefficiency of the driving shaft up to the instrument is detected, and with it, the value ofthe current is determined for a zero torque.
