  "textContent": "A drive control for a three-phase motor has an inverter with multiple switches for generating three-phase voltages on the windings of the three-phase motor, and a control device for controlling the switches of the inverter on the basis of pulse-width modulation. The control device is set up to control the switches in a switching period by using a switching pattern, wherein the switching pattern is composed of two active voltage space vectors and multiple null vectors, wherein the null vectors vary within the switching pattern.",
