| titleOfInvention | Method for determining the rotor angle of a synchronous machine and drive for carrying out the method |
| abstract | Method for determining the rotor angle of a synchronous machine, in particular using only a single two-component or three-component current measuring channel, and drive for carrying out the method, in particular wherein the synchronous machine has a stator inductance that is dependent on the rotor position, wherein an inverter supplies the stator of the synchronous machine with a pulse-width-modulated three-phase voltage which can be identified by a voltage space vector for each half of a pulse width modulation period, wherein the motor current is measured and is used to form an associated motor current space vector and, at least on the basis thereof, the voltage space vector is determined at least for a particular pulse width modulation period, wherein the voltage space vector is composed of a component associated with a fundamental component and of a component associated with a carrier signal at a higher frequency than the fundamental component, wherein the carrier signal is in the form of a periodic signal, the period duration of which is an integer multiple of the pulse width modulation period, in particular is at least two or three times the pulse width modulation period, wherein the carrier signal is a binary signal, wherein the carrier signal has a pattern without average values, in particular when averaging over the period duration of the carrier signal, wherein the carrier signal can be clearly identified by virtue of a voltage value being associated with each half of a pulse width modulation period, wherein the fundamental component of the voltage space vector is constant during the period duration of the carrier signal, wherein the current component associated with the fundamental component and the current component associated with the carrier signal are determined from the measured current values. |
