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.

An electrical machine device, comprising:
- an electrical machine;
- a first vibration component generated in the electrical machine;
- a converter that converts electrical power, the converter being electrically coupled to the electrical machine;
- and
- a second vibration component generated in the electrical machine;
- wherein the configuration of 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.
A method of operating a converter, the converter being coupleable to an electrical machine which generates a first vibration component, the method comprising:
- generating a second vibration component such that the second vibration component at least partially destructively interferes with the first vibration component generated in the electrical machine.
