Vibration and noise control strategy in electrical machines
Abstract:
An electrical machine device is disclosed, the electrical machine device including an electrical machine and a converter electrically coupled to the electrical machine. A configuration of the electrical machine generates a first vibration component in the electrical machine and the converter generates a second vibration component in the electrical machine. The electrical machine and the converter are adapted to each other such that the first vibration component and the second vibration component at least partially interfere destructively. Further, respective methods and computer programs for controlling a converter or operating a converter are disclosed.
