摘要：A method for the noise modulation of a three-phase synchronous electricmotor driven using a vector regulation by means of a motor control unit. Actual values
for the rotated current components iand imay be obtained in an open-loop controlsystem, where icorresponds to the magnetisation current and icorresponds to thetorque-forming current of the synchronous motor. The actual values may be comparedwith predetermined reference target values, and the differences between the actualValues and the reference target values may be converted into control variables toregulate the actual values (i, i) to the reference target values. The magnetisation current-forming: current component (i) may be adapted using an acoustic controller to a desiredacoustic state depending on an acoustic state that was measured by a measuring deviceand was transmitted to the motor control unit.
