method for reducing engine noise, adjusting device for reducing engine noise, and propulsion system

摘要

The invention relates to a method for reducing noise from a motor (1) powered by a converter (2). In order to reduce noise generation, the magnetic flux (f) in the motor (1) must be altered such that the product of the fundamental magnetic flux oscillation (f) and a harmonic magnetic flux oscillation (f) are reduced. . additionally or alternatively, the voltage (us) on the motor (1) and / or the pulse frequency (fp) and / or the intermediate circuit voltage (uzk) must also be changed.
