초록 ▼

A method for controlling a rotating-field machine supplied from an inverter, the output voltage system of the inverter being variable with respect to amplitude, phase and frequency includes supplying amplitudes of stator flux components formed from measured stator current components and stator voltage components as actual value of a flux control loop, and changing the phase and frequency of the inverter output voltage system with a flux control as a function of a predetermined stator flux reference value by directly setting-in the switching state of the inverter and an apparatus for carrying out the method.

대표청구항 ▼

Apparatus for controlling a rotating-field machine, comprising: an inverter having an output voltage system being connected to the rotating-field machine and being variable with respect to amplitude, phase and frequency; an integrator connected to said inverter and a component converter connected to said integrator for forming amplitudes of stator flux components from measured stator current components and stator voltage components as actual values of a flux control loop; means for supplying a predetermined stator flux reference value; and a flux control in the form of a comparator having inputs connected to said component converter for receiving the amplitudes of the flux components and to said supplying means for receiving said stator flux reference value, and said flux control having an output connected to said inverter for delivering switching state variables for driving said inverter, said flux control changing the phase and frequency of the inverter output voltage system as a function of said stator flux reference value.
