Abstract
The invention relates to a method for operating an electric machine. A harmonic manipulated variable with respect to a harmonic of a predetermined frequency occurring during the energization of the electric machine is determined. The electric machine is energized using the determined harmonic manipulated variable by means of a pulse width modulation method. For each period of the pulse width modulation method, the harmonic manipulated variable is determined for both a switch-on operation and a switch-off operation.
