FIELD: medicine.SUBSTANCE: actuator control device for the surgical motor system contains a motor control unit (MS) to control the motor (M) in an open and/or closed loop. This motor drives the surgical instrument (W). The actuator control device includes a parameter description device (PV) that is installed in front of the motor control unit (MS) and determines the current medical application based on the determined state or history of the surgical motor system state, in particular the motor (M), selects a control mode suitable for the said medical application, and provides the motor control unit (MS) with such parameters of an open or closed loop, so that the control profile in the open or closed loop of motor (M) corresponds to the selected control mode. The surgical motor system comprises an electric motor (M) to drive the surgical instrument (W) that can be removably connected directly or indirectly to the said motor, in particular by inserting a tool or tip adapter, and the aforementioned control device. The method for control of the motor (M) of the surgical motor system in an open and/or closed loop comprises the following steps: surgical motor system motor (M) state and/or history of state determination； determination of the current medical application of the surgical instrument (W) based on a particular condition or background of the condition； control mode selection based on the specific medical application； and adjustment of the open or closed loop parameters, so that the motor control profile (M) in the open or closed loop corresponds to the selected control mode.EFFECT: invention allows the motor to operate smoothly and without jerking, in particular, also at particularly low speeds, and allows a very rapid adjustment of rotation speed.11 cl, 3 dwgГруппа изобретений относится к медицинской технике, а именно к хирургической двигательной системе, устройству управления приводом для упомянутой хирургической системы и способу управления электродвигателем уп
