摘要： A method for operating an electrically commutated machine. In at least one method step, in particular in at least one method step of overmodulation operation of the electrically commutated machine, a precommutation angle of the electrically commutated machine is set depending on an efficiency of the electrically commutated machine.

摘要： A method for determining an interrupted motor phase of an electric motor having at least three windings by means of a control unit is disclosed, wherein voltages induced in the windings are determined on outer conductors of the electric motor by means of at least one measuring unit, wherein the measuring unit is connected to at least one outer conductor of the electric motor via at least one resistor, the induced voltages of the outer conductors of the electric motor are compared with one another, and an interrupted motor phase is registered if the induced voltage differs or if a frequency of the induced voltage differs. A control unit, a computer program and a machine-readable storage medium are also disclosed.
