Abstract
To improve a surgical machine with an electric motor comprising a rotor and a plurality of motor windings, and with a motor controller for controlling and/or regulating the electric motor so that, in particular, the efficiency of the electric motor can be optimized essentially over the entire rotational speed range, it is proposed that the entire rotational speed range of the surgical machine be divided into at least one lower rotational speed range for low rotational speeds and at least one upper rotational speed range for higher rotational speeds than those in the at least one lower rotational speed range, that the motor controller be so designed that a first controlling and/or regulating method for controlling and/or regulating the electric motor is performable in the at least one lower rotational speed range, and that a second controlling and/or regulating method for controlling and/or regulating the electric motor is performable in the at least one upper rotational speed range.
