摘要： A method for determining the rotor angle of a synchronous machine. In one implementation, the method includes generating a multiplicity of pulse-width-modulated drive signals for the phases of an inverter feeding the synchronous machine depending on a voltage to be fed into the synchronous machine, changing the pulse width modulation frequency of at least one drive signal of the multiplicity of pulse-width-modulated drive signals, with the result that the duration of the switching states of the inverter in which an active voltage phasor is output is extended in order to generate a switching pattern for the phases of the inverter, driving the inverter with the generated switching pattern, determining one or more of neutral point potentials at the neutral point of the synchronous machine during driving of the inverter with the switching pattern, and calculating the rotor angle of the synchronous machine depending on the determined neutral point potentials.

摘要： 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.

The method comprises the following steps: specifying (410) a first signal (S_1) for generating a sinusoidal phase current for energising a winding of an electric machine (120); superposing (420) the first signal (S_1) with a test signal (S_Test_i) in order to generate a harmonic oscillation with a predetermined excitation amplitude and/or phase position relative to the phase current, which harmonic oscillation superposes the phase current; detecting (430) a response signal (S_Antw_i), resulting from the superposition of the phase current and the harmonic oscillation, by means of a sensor (130); determining (450) a calibrated signal (S_kal) for generating a harmonic oscillation with a predetermined excitation amplitude and a phase position relative to the phase current on the basis of a determined minimum of a response plane (A_Antw); operating (460) the controller (110) of the electric machine (120) on the basis of the determined minimum.
