Abstract
A method and device for operating an electrically commutated machine having a rotor on which a first gear of a transmission can be situated, wherein a comparison value is determined as a function of an instantaneous angular position of a second gear of the transmission that is capable of being connected to the first gear for the transmission of torque, and a target value for an manipulated variable of the electrically commutated machine is determined as a function of the result of a comparison of the comparison value with an instantaneous value of an operating variable of the electrically commutated machine.

A method for operating an electrically commutated machine having a rotor on which a first gear of a transmission is situatable, the method comprising:
- determining a comparison value as a function of an instantaneous angular position of a second gear of the transmission that is connectable to the first gear for transmitting torque;
- and
- determining a target value for an manipulated variable of the electrically commutated machine as a function of the result of a comparison of the comparison value with an instantaneous value of an operating variable of the electrically commutated machine;
- wherein an actuator lever is connectable to the second gear for the transmission of the torque via a third gear, a belt drive, a chain drive, or a worm drive, an absolute position of the actuator lever being determined as a function of the result of the comparison.
A device for operating an electrically commutated machine, comprising:
- a control device configured to operate the electrically commutated machine, wherein the electrically commutated machine has a rotor on which there is situated a first gear of a transmission, a second gear of the transmission being connectable to the first gear for transmitting torque;
- wherein the control device is configured to determine a comparison value as a function of an instantaneous angular position and to determine a target value for an manipulated variable of the electrically commutated machine as a function of the result of a comparison of the comparison value with an instantaneous value of an operating variable of the electrically commutated machine;
- wherein an actuator lever is connectable to the second gear for transmitting the torque via a third gear, a belt drive, a chain drive, or a worm drive, and wherein the control device is configured to determine an absolute position of the actuator lever as a function of the result of the comparison.
