METHOD FOR OPERATING A THREE-PHASE MOTOR ON A DIRECT-VOLTAGE NETWORK, INVERTER FOR THE METHOD, SYSTEM HAVING AN INVERTER, AND METHOD FOR PROVIDING A THREE-PHASE MOTOR

摘要

The invention relates to a method for operating a three-phase motor on a direct-voltage network. The method comprises generating a three-phase system having three pulsed voltages (UR0, US0, UT0) having phase-shifted pulse patterns, wherein half-waves of a fundamental wave of a first to third linked output voltage (URS, UST, UTR) have at least one main pulse (110) and wherein a common fundamental frequency of the linked output voltages is greater than 60 Hz and less than or equal to 150 Hz.
